How Bad is My Oil Leak?

oil leaks

So your car leaks a little bit of oil.  How big of a deal is that?  If you drive into the nearest apartment complex you will see oil stains in just about every parking spot.  If everyone’s car leaks oil, it must not be a big deal … right?  Maybe, but are you willing to bet a new motor for your vehicle on that?

In reality, it depends on a few different factors:

  • Leak size and location
  • Time or miles driven per day
  • Engine oil capacity

First, it depends on the size and location of the oil leak. Some leaks will drip while the engine is running, while others will leak whether the car is running or just sitting parked.  It also depends on how much you drive.  For some leaks this will mean more oil lost, but for all leaks, the more you drive, the sooner you will have the oil supply in your engine replenished to the proper level during an oil change.  Lastly, it depends on how much oil your car engine holds.  If you have a 100 series Land Cruiser with the giant straight 6 motor that holds almost 9 quarts of oil, a small drip will not affect the oil level much.  On the other hand, if you have a Saturn sedan with a 4 cylinder motor, a few days of dripping may significantly affect oil level.

The goal in the end is to maintain a safe oil level in your vehicle’s engine.  A proper oil level will ensure the oil pump can draw oil up from the oil pan, and push it through the oil filter so it can be distributed to the important moving parts in the engine.  A proper oil level will also ensure proper lubrication of the crank shaft, connection rods, pistons and piston rings.  Lastly, especially in performance motors or heavy duty trucks, engine oil can reach high temperatures during heavy loading and a proper oil level can ensure the oil does not get over heated and break down.

Given that the severity of your oil leak depends on so many factors that cannot be determined by looking at the size of the puddle left, or number of drips you see, it is important to regularly check your engine oil level on your dip stick.  This is the best way to make sure your engine is safe to operate.  Also, if you check your engine oil level at a regular interval, it can help you determine the severity of your oil leak, or if you know you don’t have any leaks, how much oil your engine is burning while its running.  Some oil consumption is normal, depending on the make and model of your car, but you still should never let your oil level drop below the minimum level.

A good interval to start checking your oil at is once per week.  Set a specific time of day or location to help you remember.  If you check your oil for 4 consecutive weeks without seeing a significant change, you can consider checking it every other week, or once per month.  At a minimum, check your oil once per month and before any long trips.

Oil LeaksIf you notice your oil level steadily dropping during your regular checks look for oil stains on the ground after it has been parked for more than an hour.  Also, you can look at the bottom of the engine to see if there are any oil spots or drips.  Trace the oil leak up to the highest point to determine the source.  If you notice a significant drop (more than ¼ of the dip stick) in a week’s time, check carefully for new leaks or other problems.

 

If you’ve identified a leak, add BlueDevil Oil Stop Leak to your engine oil.  One bottle treats up to 6 quarts of engine oil and will seal the oil leak as you drive.  BlueDevil Oil Stop Leak repairs and reconditions the rubber seals in your engine as you drive to seal the leaks saving you oil and keeping your engine safe.

  1. I have a 98 Honda Accord LX it has over 200,000 miles on it I’m due for an oil change but the last two weeks I’ve been having to put at least one quart of oil in my car a day I know I need to get my oil changed it might be the seal that’s a lot of oil in it

        1. Brenda-

          Yes, BlueDevil Oil Stop Leak is compatible with your Mercedes Diesel. You should add 1 ounce of BlueDevil per every 1 quart of oil. Once BlueDevil is added you can expect to start seeing results after about 100 miles of driving.

          Thank you!

  2. I have a 2004 Volkswagon Beetle Turbo X 1.8L, my oil has been leaking for about a month now. I have had to buy 2 quarts of oil every two days to keep it running. I drive it everyday and at least 300 miles a week so the oil goes quickly. It seems to drip the most overnight while it sits. I don’t know what it is leaking from and I’ve looked under the car and it is just constant dripping. Will getting my oil changed and putting in BlueDevil Oil Stop Leak help this issue?

    1. Mi’Kayla-

      Your VW is on the border of having a leak that is a bit too extreme. However, we do recommend giving the BlueDevil Oil Stop Leak a try based on your description. You should notice results after about 100 miles of driving.

      Thank You!

  3. I have a 1999 Lexus Gs300 with 192K miles. I’ve noticed sporadic oil leaks in the driveway over the past 2.5 months. I was told by a mechanic that a majority of the leak is from the Cam seals. Would this product provide any significant relief?

    1. Ariel-

      Yes, the BlueDevil Oil Stop Leak will work to seal your cam seals. After adding the product you should notice results after about 100 miles of driving.

  4. I’ve got a 2004 BMW X5… It’s leaking oil. I can tell.. it on my driveway…it’s about the size of a half dollar. What should I do.

  5. Hi , I have a 84 ford escort xr3 with a 1600 cvh motor, it only drips oil when the motor is runnig, but nothing when its standing still. think its the crankseals. will stopleak help?

      1. I have a 2002 Yukon and its leaking oil. I have to add a quart once a week and I drive maybe 2-300 miles a week. Can I put the stop leak in at any time or should I wait.

  6. Hello I have a really bad oil leak when the car is running or not running it leaks really bad. Im having to put 3-4 quarts in it a week, Will this work for me? Is it just a thicker oil or does it make a seal where the leak is?

    1. Brittany-

      Based on your description, it sounds like you may have a leak that is larger than what BlueDevil is intended to fix. We recommend the vehicle is taken to a mechanic to be repaired.

  8. Hi, I have a 2013 Chevy Cruze RS that I just purchased a few weeks ago. A couple days ago, after driving I noticed there was a little bit of white smoke coming out from the hood of the car. Concerned I checked and found that my oil cap had come undone. I put it back and wiped all the oil that I saw had spilled off of everything. I didn’t drive it for a couple days, and today I drove it for maybe 15 miles and once being home and being turned off again, white smoke still began to appear. I checked again and the cap to the oil was on. This time however, is sounds like there is something drilling from inside. Will putting this in there help the dripping and Is the smoke from oil being burned from when it was spilled and I couldn’t reach to wipe off or something else? Thank you

    1. Katie,

      Thanks for your question about your Chevy Cruze. It does sound more like you simply had a mess from your oil cap being off rather than an actually oil leak. When your oil cap was off you probably got more than just a leak but oil spitting and splattering out of the oil cap hole so you might have more of a mess than you bargained for. There also is a plastic cover over your engine that is probably hiding a lot of the mess. You can try removing that cover and do some more cleaning but at the end of the day you may just have to wait until the oil burns off.

      You should also consider checking your engine oil level just to make sure you didn’t loose too much oil while your oil cap was off.

  9. I just bought a ’03 Land Rover & noticed oil dripping all over the bottom of engine. Haven’t had time to source the leak yet since I just caught the leak 5-6 days ago but I topped it off & had to add 1/2 qt today. If possible I want to repair the leak when I can but in the meantime I suppose this would help wouldn’t it? Also, does it specifically work just by expanding & lubing dried old gaskets/seals or does it partially block any small holes? Reason I ask is, I read a “mechanics” thread where he personally didn’t use sealers because he thought that being a sealer, it may block a small passageway to a vital part overtime from buildup Thanks, Seth

    1. Seth-

      We recommend adding 1 bottle of the BlueDevil Oil Stop Leak. The BlueDevil works by reconditioning & slightly expanding the gasket/seal; the product does not harden or thicken at all. There is no risk at causing any type of harm or restricting flow.

      Once the product is added you can expect to notice results after about 100 miles of driving.

      Thank You!

  10. Hi,
    My 99 Camry has a lot of miles on it, and recently I took it to have an oil change. The guys told me to take it to a shop as it has a severe oil leak. The problem I have is, there has never been any oil in my drive way or at my work. The car is indeed low on oil from time to time, but it doesn’t smoke or seem to be burning oil, so I have no idea what I should do. Any advice at this point would be greatly appreciated. Thank you in advance!!!

    1. Jason,

      Thanks for your question about your Camry. If you’re losing oil but don’t have any drips it must be burning. It could be burning externally via a high leak onto the exhaust manifolds. Usually, this would be a valve cover leak, but you would most likely smell the burning oil in the cabin of your vehicle after driving for more than a few minutes. It could also be burning internally either from worn valve seals or worn piston rings. An internal oil leak like the last 2 described usually means your motor is worn out and your only option is to continue to add oil until you can rebuild the motor.

      It’s also possible you have an oil leak but it only leaks while driving like a camshaft seal leak. If that is the case it would drip while you’re driving but once you’re parked it only drips from residual oil not leaving a puddle or enough drops for you to see. If that is the case you should still be able to see an oily mess in your engine bay or on your engine block to help you locate the leak.

      Thanks again for your question!

  11. Hi, i have an 04 honda civic, ive owned it for about two months and have noticed a small oil drip in my driveway, in these two months i have put about 2500-3000km on the vehicle and have only had to put less then half a quart of oil in it, but it still makes me worry. From what i can tell the oil is coming from somewhere on the oil pan. Just wondering if this stuff would be any good to try for the problem im having. thanks

  12. 06 trailblazer 4.2 small oil leak appx. size of a quarter. just had oil and filter change less than 1000 miles ago 7 qt. capacity with oil filter. is one 8 oz. bottle of Blue Devil stop leak enough or should I get 2 bottles and add say another 2-3 ounces over the 1 full bottle. also will the appx. 1/3 of qt. over capacity hurt engine ?

    1. Joe-

      You will only need to add one 8 ounce bottle of the BlueDevil Oil Stop Leak to treat your Trailblazer. Once the product is added you can expect to start seeing results after about 100 miles of driving. The 8 ounce bottle will not effect your oil levels.

      Thank you!

  14. I have a 2005 jeep grand Cherokee and im not sure where the oil is going to i did notice that it was leaking oil before and i had change the oil pan gasket and did a oil change as well. but after a 2 weeks i notice my oil light came on saying i need oil again and im not sure where is it going because i don’t see it leaking or anything, i also checked the filter and it is on there tight. is there something else i could check??

    1. Esmeralda,

      If you cannot see any oil leaks, drips or puddles it can be difficult to track down the location of an oil leak. if you’re sure there are no external oil leaks then its most likely that your oil is leaking internally past your piston rings or valve seals. if this is the case you would notice blue or black smoke coming from your exhaust and your spark plugs fouling or turning all black. That would seem a little unusual unless your Jeep has very high mileage so we would recommend watching for a few more days and looking for external leaks or drips.

      Thanks again for your question!

  15. I have a 1996 vw cabrio.. my oil light recently came on, I added the oil, started my car and I heard a strange bubbly noise? so I turned off my car got out and looked, and all the new oil I poured into it poured straight out to the ground? why? I was pouring it in the correct spot.

    1. Tesla,

      Thanks for your question about your VW Cabrio. It sounds like you’ve got a pretty major oil leak somewhere. If the oil didn’t drain out until you started your car, then the leak must be somewhere above your oil pan. A leak that big would be enough to drop your oil level quickly so we would recommend identify and fixing the leak before your drive your car again. Unfortunately, this leak also sounds too big for our stop leak products to seal.

      Thanks again for your question!

  16. 1995 firebird 3.4L. Approx every 150 miles it has lost 1qt of oil. It leaks from somewhere only when running and when parked any oil leaked into the cover between engine and tranny drips out. car was sent to mechanic who diagnose a rear main seal leak. that seal was replaced and the mechanic called and said it is still leaking and suggested a different place is leaking. Told me that the way the engine is tucked it will require removing the engine to find the leak, so whether the seal around distributor shaft head, valve cover, oil sending unit, etc are leaking, what can this product do for it especially when I am told some of the seals are not rubber and are either cloth or plastic? I tried a different stop leak already to no avail…

    1. Mick-

      Thank you for asking about your Firebird. Based on your description, we would recommend using the BlueDevil Oil Stop Leak. The product would help seal leaks coming from the rubber seals or rubber gaskets in the system. You should start to see results after about 100-200 miles of driving.
      The product would only be for the rubbers in the system. If the seals are made of cloth, plastic, cork or rope, the product would not have any effect on those materials and would not be able to seal the leaks. The product doesn’t harden or thicken in any way, so it would not have any adverse effects on the engine, even if the seals are not rubber. Feel free to contact our technical support line at 888-863-0426 with any other questions.

  17. I have an oil leak that just started happening. Overnight when not running an oils rain the size of a dinner plate appears. My level seems fine. Should I be concerned

    1. Jasaiz,

      Thanks for your question about your oil leak. If you had an oil leak that big appear in 1 day, we would recommend having the problem checked out by a mechanic soon. Even if your oil level is correct today, a leak that bad can cause a low oil level very quickly. You can try using BlueDevil Oil Stop Leak (available here: http://store.gobdp.com/oil-stop-leak-49499/) but your leak may already be too big.

      Thanks again for your question!

  18. Hello my car is leaki.g oil and i was told by my brother its my oil pan gasket or the bolt that lets your oil out when changing your oil is leaking slowly will the blue devil stop leak work in my case ?

  19. I forgot. To mention. That it only leaks when parked and its not a big puddle of oil but i have to add oil after a few days

    1. Andrea,

      Thanks for your question about your oil leak. If the leak is coming from your oil pan gasket BlueDevil Oil Stop leak (available here: http://store.gobdp.com/oil-stop-leak-49499/) will restore the gasket and seal your leak. If the leak is indeed coming from your drain bolt, BlueDevil Oil Stop leak will not be able to stop the leak. If that is the case, we would recommend replacing your drain plug washer next time you have your oil changed.

      Thanks again for your question!

  20. I have a 2006 ford explorer v6 automatic. today, this morning my truck was driving just fine ,gears were changing good the rpms were good, I had to make a sudden stop because a car in front of me suddenly stopped also. about time I was going to accelerate I the rpm wasn’t on 0 so when I pushed the gas the truck didn’t move until maybe 3 seconds later. I stopped to pick my kids up and I noticed a huge leak so I got some on my finger and noticed it was red oil, got home and noticed the oil leaking from the front of the truck close to the radiator and lots of oil. I took it to the store down the street and it did fine going in reverse but when I put it in drive it took a few seconds to move and jerked when it did.

    1. Crystal,

      Thanks for your question. It sounds like you’ve got a transmission fluid leak coming from the line from your transmission to your radiator. Your truck runs its transmission fluid through a small portion or your radiator to help keep the fluid cool. There should be two smaller lines running into your radiator from your transmission, usually at the bottom. Check to see if one of those lines is crack, burst or broken. You should be able to replace that line, refill your transmission with fluid, and get back to normal relatively easily.

      Thanks again for your question!

  21. Hi – I have a 2010 207 Peugeot. She has been well looked after, serviced professionally on time as required etc. immediately after my last service, my car started to leak oil. Small spotting. I took it back and was advised this was normal. However, the leak has gotten steadily worse and now puddles badly when stationary. Can you comment please?

    1. Lynn,

      Usually, oil leaks that get bad that quickly are on shafts seals so we’d recommend inspecting your crank and cam shaft seals. Make sure to check your oil level regularly until you get the leaks fixed. For this type of leak, we’d recommend using BlueDevil Oil Stop Leak (available here: http://store.gobdp.com/oil-stop-leak-49499/)

  23. I have a 1998 Honda Civic LX with 170k on it and I just noticed an oil leak. I believe its coming from the craft shaft pulley seal. it’s drips every hour or so. Do you think if i buy the stop leak product it would stop my leak?

  24. I have a 97 ford escort. It leaks oil so I checked it and added 2 quarts. It is now leaking worse and smoking from under the hood. Would stop leak help?

  25. Hi,

    So I recently, as in about 2 weeks ago, put the blue devil oil stoppage fluid in my car and I have seen an improvement from the size of the leaks but yet I still notice penny to dime size leaks near the front right side of the car. I drive a 2008 Dodge Avenger with only roughly 78,000 miles on it. I don’t drive it that often and was wondering whatd be the next best step? Thanks

    1. Jonathan-

      Approximately how many miles have been put on the Avenger since BlueDevil Oil Stop Leak was added? It will usually take 100 – 200 miles before you see full results from BlueDevil after it is added to your oil. You had mentioned that you do not drive a whole lot so that may be why you haven’t seen the leak completely stop yet. The fact that the leak has started to slow down is a good sign.

      Thank you!

      Thank you for asking about your Dodge Intrepid. The BlueDevil Oil Stop Leak is intended for leaks that are seeping or lightly dripping. Typically, you should start to see results after about 100-200 miles of driving. As long as you are not losing oil too quickly, you would be a good candidate for the product.

  30. I have a 2000 Honda Accord, I put 5quarts of oil in my car on Saturday and it is about all gone now and it leaks out everytime I drive and it smokes as well. Could I use BLUE DEVIL to see if it will stop the leaking of the oil?

    1. Jasmine-

      Thank you for asking about your Honda Accord. Unfortunately, you may be losing oil a little too quickly for the BlueDevil Oil Stop Leak to be effective. Typically, you would start to see results after about 100-200 miles of driving. If you are losing your entire oil capacity in a couple of days time, you would be losing the product just as quickly, and wouldn’t really be able to keep it in the system long enough in order to get the benefit of using it. A hard part repair may be your best option.

      Thank you!

  33. Hi, I just purchased a 1997 Jeep Grand Cherokee. It does have a lot of miles on it. I noticed today small oil leaks. One located at the rear of the vehicle and one small one at the front where I believe the oil drip pan is located. Tried taking a look under the hood as well as underneath the jeep to locate the leak. It has me a little nervous because the very first car I bought head gasket went from having no oil. Also I smell burning from the hood when I park from driving it, but no smoke. I checked the oil levels and it looks to be between SAFE and ADD. I plan to get an oil change this week to be on the safe side. Any suggestions on what it may be? Thank you!

  34. Hi, I own a 2002 Honda Accord V6. My car has been leaving oil stains on my driveway for over 6 months. It is still leaking because when I put a cardboard under my car, there will be fresh oil stains. It is a very slow leak because I have never had any need to add engine oil. I changed the oil over a month ago and the dipstick still shows the oil at full. I don’t drive the car often. Maybe once a week. Does your product seem like something that can help me?

      Thank you for asking about your Honda Accord. Based on your description, you would be a great candidate for the BlueDevil Oil Stop Leak, http://store.gobdp.com/oil-stop-leak-49499/. You should expect to see results after about 100-200 miles of driving. It does not have to be a continuous drive. You are fine to drive the vehicle like you normally would, it will just be around the 100 mile mark before you start to notice improvement.

  35. Hi, I have a 2000 Honda accord and I am having to add two quarts of oil a week. I took it to a lube shop and they said it was leaking from the valve cover. So i replaced all the gaskets and it is still leaking. Will your product work with the amount of oil i have to put in on a weekly bases?

    1. Michelle-

      Thank you for asking about your Honda Accord. Typically, you would start to see results after about 100-200 miles of driving. If you are losing oil so quickly that you would be losing the product before you were able to get to 100-200 miles of driving, unfortunately, the leak you are experiencing may be a little larger than what the product is intended for. A hard part repair may be your best option.
