Dura-Seal Engine Oil Stop-Leak® works by re-impregnating seals with silicone, they absorb what they've lost over the years and expand back to their original size, stopping the leak! Our Oil Stop-Leak formulas contain no "thickening agents" or "silicates" like Bars, Blue Devil, STP or Lucas so their are compatible with all engine oils and cannot cause clogging or damage. Dura-Seal® Oil Stop-Leak works with synthetic, diesel rottela and conventional oils and can be used in motorcycles. Easy to use, simply add to existing oil and leave-in till next oil change. One treatment typically last up to 5 years...

Dura-Seal® Hi-Strength Oil Stop-Leak is different than all store-brands! These other brands try to stop the oil leak by simply making the engine oil thicker. That's ridiculous! That doesn't fix the leak it just slows it down, at best.

Our Dura-Seal® Hi-Strength Oil Stop-Leak is manufactured to be smarter than that. Our Dura-Seal® Oil Stop-Leak doesn't thicken your oil, so theres no risk of increasing the engine oil compression and burning out the valve guides. Instead, our oil stop-leak actually causes all the oil seals in your engine to expand back to their original size. Our method, doesn't effect your oil in any way. So you can use it in any type of engine, (gas or diesel) and any type of engine oil including; regular, synthetic, and even rotella!

There is no negative effect on your engine by using our Dura-Seal® Hi-Strength Oil Stop-Leak. It cannot harm your engine. It cannot gum-up your system, as it simply does not contain thickening or binding agents of any kind. Let's face it, you get what you pay for. Dura-Seal® Hi-Strength Oil Stop-Leak is an extremely advanced formulation, it's unlike any oil stop leak you've ever bought in the past and there is nothing like it available at any auto-parts store.

Still have questions? Need more help..? Call Us: Mon-Fri. 9am to 5pm. EST 706-400-0897
Dura-Seal® provides you with a Free Replacement Warranty on all Oil Stop-leaks in case you need more sealer to then typical to achieve a full-seal, (*certain conditions like S/H may apply, see Terms). 98% of customers achieve a "full-seal" on the first application.
