Best Oil Stop Leak

#driveyourlife

Any moving equipment needs some way to be lubricated and oil is often the best choice.  Lubrication is so important in machinery because it is often supporting extremely heavy loads while moving or rotating a very high speeds.  In order to accomplish this, lubricants need to be used in order to lower friction to keep temperatures and wear down.  Without any lubrication, most pieces of equipment would not be able to move for very long before overheating or grinding to a halt.

The engine in your vehicle is no different.  Without the proper lubrication, the bearings and piston will quickly overheat causing certain components to melt, deform, and ultimately stop moving without the hope of ever starting again.  The oil in the engine of your car is the key to keeping things cool and slippery so that the surfaces that are in contact with each other don’t create too much heat, don’t wear each other out, and in some cases don’t even touch.  The oil in your engine is stored in the oil pan and pumped to where it needs to go by your oil pump.  After it has been pumped through your engine lubricating the cams, valves, bearings and anything else, it drains back to the oil pan where it collects so the oil pump can send it back through the engine.

The difficult part of this process is keeping the oil where it needs to be, and that’s why oil leak sealant can be so important.  Anywhere a shaft exits your engine, such as your crankshaft or camshaft, is a possible leak point.  Also, any gasket in your engine where two components are joined together like the valve cover gasket or oil pan gasket is a possible leak point.  Lastly any hose or attachment that carries oil has the possibility of leaking oil out during operation of your engine.

What is the cause of oil leaks?

dipstickLeaks are bad for a few reasons.  First, they make a mess.  An oil leak can spread all over external components on your engine such as the hot exhaust where it can burn, or on electronic components that it will damage.  Second, big enough oil leaks can change the pressures and the way oil flows in your engine which may lead to poor lubrication and other problems.  Lastly, an oil leak will cause the level in your oil pan to slowly lower until your oil pump has no more oil to pump.  This also can lead to poor lubrication and all the problems we listed above.

Many of the places oil will leak from in your engine are difficult to get to.  That means replacement of the seals and gaskets can be a time consuming and expensive process leaving you stranded without a car and with a hefty repair bill.  That is why the first oil stop leak products were invented.  Imagine a simple formula you can pour into your engine that will stop your leaks!  A product like that could save time and money and would be worth every penny!

The first engine oil stop leaks worked mainly by clogging up the hole where the oil was leaking from.  Some of the first patented oil stop leaks were no more than castor oil and ground nut shells.  The ground shells would mix with the oil and flow to the leak point where they would literally clog the hole to stop the leak.  Stop leaks like this caused problems because the ground nut shells, or later sawdust, or aluminum shavings would clog other things, or create more wear in the motor.  These types of stop leaks work in theory but, in the long run, do more harm than good.  Some later oil leak repair products would use chemicals like petroleum distillates that did not have particulates to clog the leak but would instead swell the seal or gasket causing it to seal properly and stop the leak.  The problem with these chemicals is that they do swell the gasket for a short time, but they also will cause all the seal or gasket to deteriorate quickly so you will soon have a worse leak than you started with.

What kind of oil stop leak should I use?

The best kind of oil stop leak is one that does not have particulates to clog your engine or petroleum distillates to deteriorate the existing seals.  BlueDevil Oil Stop Leak is the best oil stop leak on the market because it is specifically designed to absorb into all of the seals in your engine expanding and revitalizing them back to their original size, shape and flexibility without later destroying them.

          Damian-

          Do you happen to know where the leak is coming from? Oil blowing out of the exhaust pipe could indicate a head gasket leak, which unfortunately, The BlueDevil Oil Stop Leak would not be recommended. Please contact our technical support line at 888-863-0426 so that we can get a better understanding of the vehicle’s condition and be able to make any appropriate recommendations.

        Blnd-

        The BlueDevil Oil Stop Leak can stay in the oil for the life of the oil. It does not need to be changed out immediately after results are achieved. You can leave the product in the system until your next scheduled oil change.

      Will it fix the blue smoke coming out of exhaust because of bad rings

      • BlueDevil Pro on June 10, 2019 at 9:31 am

        Austin-

        If the blue smoke coming from the exhaust was attributed to bad o-rings, yes, BlueDevil Oil Stop Leak would be able to treat that kind of a leak. Blue smoke coming from the exhaust pipe can also be related to a head gasket leak, which unfortunately, we do not manufacture a product for that kind of a leak.

        Hope this helps!

        • BlueDevil Pro on May 1, 2023 at 8:56 am

          Boston-

          The BlueDevil Oil Stop Leak does not harden or thicken in anyway, so it would not “fill in a hole” or “plug up a gap.” It works by revitalizing/reconditioning rubber seals/gaskets. Unfortunately, it does not sound as though it would work for your application.

          Thank you!

          Lance-

          You should only need to use the product once. Once the BlueDevil Oil Stop Leaks seals, it would be a permanent seal. It is not the kind of thing you would have to add with every oil change.

        “Will your product work stopping a ring seal leak?”

        Are you sure this will slow or stop ring leakage ? My golf cart Yamaha engine is getting a lot of blow by and I am not too sure that a ring job can help very much since the engine had a lot of baked on grease and has probably been hot. That is why I am considering your product , since a golf cart is run only intermittently at the best it would take a long time to get 100+ miles on it, so can I really expect favorable results from your product in my situation ? Thanks Richard Shanks

Once the product is added you can expect to start seeing results after about 100 miles of driving. It does not have to be a continuous drive. You are fine to drive the golf cart like you normally would, it would just be around the 100 mile mark before you would start to notice improvement.

      BlueDevil Oil Stop Leak is 100% safe for engines. The product does not harden or thicken at any point and therefore will not restrict flow or harm any component of the engine. BlueDevil Oil Stop Leak works by slightly expanding and reconditioning the rubber seals & gaskets in the system. Once the product is added you can expect to start seeing results after about 100 miles of driving.

      If you are losing oil that quickly then you probably have a leak that is larger than what BlueDevil Oil Stop Leak is intended to fix. The product would be lost too quickly if the system is losing its entire oil capacity within 100 miles.

      The BlueDevil Oil Stop Leak is the universal application and will work for oil pan leaks, rear main leaks, valve seal leaks, etc. Whereas the Rear Main Sealer is specifically formulated for the rear main seal.

    Once Blue Devil oil stop leak is added into your oil lubricating system and the engine has ran for 1 – 2 hours or for 100 – 200 miles, is it required to change the oil if the vehicle isn’t due a scheduled oil change?

      BlueDevil Oil Stop Leak can stay in the system for the life of the oil. It is not necessary to change the oil, once the product has been able to seal, until your next scheduled oil change. The product does not harden or thicken in any way, so it will not have any adverse affects on the engine.

    I just bought an 05 caravan and noticed a smell of burnt oil after driving and here and there I smell it while driving but no leak detected on the driveway – after discovering the prior owners mechanic check in the owners manual, they noted it had a small oil pan leak. If I were to use your product – would I need to use less than a bottle as it’s only a tiny leak? and I don’t change the oil myself – would jiffy lube or other add this product for me during a change?

    • BlueDevil Pro on July 19, 2016 at 12:22 pm

      Jackson-

      Thank you for asking about your Dodge Caravan. One 8 oz. bottle would treat 4-6 quarts of oil. It is not necessary to change your oil prior to using the product. The product can stay in the oil system for the life of the oil, so it does not have to be changed out immediately after results are achieved. You should expect to see results after about 100-200 miles of driving.

      Thank you!

      Thank you for asking about your Audi A4. The BlueDevil Oil Stop Leak would not have any negative affect on the turbo. The product does not harden or thicken in any way, so it would not have any adverse affect on the system.

    I have a 2006 Subaru outback which are notorious for oil leaks from the heads. The radiator has no sign of oil in the water, just oil burning on the exhaust manifold from the drips. about 1 quart per 1000 miles. Will it work on head gasket oil leaks ?

  32. Lando on September 8, 2016 at 4:03 pm

    If used in a motorcycle with a wet clutch, where the engine oil is also used to lubricate the clutch, will BlueDevil Oil Stop Leak have any adverse effects on the friction of the clutch plates?
    I use full synthetic oil for a race bike and have to avoid oil with any “energy additives”, like molybdenum, that reduce friction because the clutch could start to slip. Does your product contain any additives that would reduce friction?

    • BlueDevil Pro on September 9, 2016 at 9:39 am

      Lando-

      Yes, you may safely use BlueDevil Oil Stop Leak in motorcycles that use a wet clutch.  You should add 1 ounce of BlueDevil per every 1 quart of capacity.  Expect to start seeing results after about 100 miles of driving. The product does not harden or thicken in any way, so it would not have any adverse affects on the system.

          The BlueDevil Oil Stop Leak is intended for leaks that are seeping or lightly dripping from any of the rubber gaskets/seals in the system. Based on your description, you may be losing oil a little too quickly for the product. Unfortunately, a hard part repair may be your best option.

    No oil leak on the pavement but it smokes a lot and it leaves a black residue on the exhaust pipe.

    Recently purchased a 99 Impreza outback sport with a difficult to diagnose oil leak. It appears to be coming from either the oil pan or possibly the rear main seal or plastic oil separator “plate” at the rear of the engine. Would the product be able to deal with these issues (i would imagine the oil separator is questionable as I believe it is a denser plastic) and do you offer some form of protection to customers should the product cause an issue of some kind to the motor? thank you.

      Thank you for asking about your Subaru Impreza. Based on your description, we recommend using the BlueDevil Oil Stop Leak http://store.gobdp.com/oil-stop-leak-49499/. The BlueDevil Oil Stop Leak is a universal application and would treat leaking oil pan gaskets, valve cover seal, rear main seal, etc. where as the Rear Main Sealer is specifically formulated for the rear main seal.

      It is not one of those things where more of the product would be better. You really do only want to go with the recommended amount. Using too much of the product could over dilute the system and limit the results you would get.

    Hello, I have a 2004 Ford Taurus SE 3.0 Vin U with an oil leak on the front by the oil dip stick. The oil drips on the exhaust and makes bad fumes in the car. I have also had a sign of the starts of a head gasket leak with traces of oil in the coolant. I’m wondering if the Oil Stop Leak and the Head Gasket Repair products you have overlap or if they can be used at the same time? Is there an order of priority when attacking this? Is there danger in using both products?

    I recently bought a 2003 Honda Civic with 58,000 miles. It was sitting for some time and has several gasket leaks.
    There may also be a transmission leak.
    Is your product safe to use with Synthetic oil?
    Is this product safe to use for transmission leaks, or do you have another product specific for transmissions?
    Your reply would be greatly appreciated.
