What is Blue Devil Oil Stop Leak?

Leaks in a vehicle’s engine are a fact of life. Age and driving exposes the engine to pressure and heat, which can cause the o-rings, gaskets and other seals within this integral car part to harden, dry up or drink.

Over time, this can cause cracks, holes and other gaps to develop in the engine, which can lead to oil leaks. Stop leak additives are non-solvent chemical formulas that are comprised of a mixture of modifiers that cause friction, as well as other refined petroleum ingredients.

These compounds are intended to minimize the amount of oil that passes through those worn seals and holes.

Essentially, stop leak additives revive the seals in the engine, allowing them to return to their normal shape, size and flexibility, thereby reducing or preventing oil leaks.

Revive Those Seals!

There are a lot of engine stop leak additives on the market, but unfortunately, many of them aren’t properly formulated.

This means that they either: 1) won’t do anything to the seals, so they won’t slow or prevent oil leaks, or 2) they could possibly do more damage to the seals and the engine, on a whole, causing an even bigger problem.


A Cost-Effective Solution…

Blue Devil Oil Stop Leak is one of the best engine oil stop leak additives currently on the market.

Created by the Blue Devil company, which has been around for years and has developed an excellent reputation for delivering exceptional products, making it one of the most trusted car additive manufacturers around.

This oil stop leak formula is made with only the highest quality ingredients. It’s designed to soak into all of the seals within the engine, expanding them and reviving them back to the size and shape that they were when the engine was first made.

It won’t clog your engine up!

This product is free of harmful solvents, such as petroleum distillates, that have a reputation for destroying seals after they initially expand them.

Unlike other stop leak products, Blue Devil won’t clog your engine or cause any other damage.

It’s also designed to be used with a wide range of diesel and gasoline engines and can treat either 4 or 6 quarts of motor oil. In fact, Blue Devil is so confident that their stop oil leak additive will work that they will fully refund your money if it doesn’t.


Directions for Use

Using the Stop Leak is pretty simple and straightforward. The directions for use are as follows:

  • Pour the entire contents of the 8 ounce bottle directly into the oil sump or crank case of the leaking component of your engine.
  • Once the solvent has been added, start up the engine and drive your vehicle.

For most leaks, the additive should seal up the leak within 1 to 2 hours. However, if your engine has an extreme leak, it could take up to 2 days of drive time for the leak to fully stop.

Here’s a short clip to help:

Blue Devil Oil Stop Leak can be used on the following components:

  • Gear cases
