Lucas Engine Oil Stop Leak is an all new formulation of Lucas additives and very specific base stocks designed to stop seal leaks in engines!

Lucas Oil Stabilizer is a 100% petroleum product formulated to eliminate dry starts and reduce friction, heat and wear in any type of engine. It allows motor oils a higher degree of lubricity which reduces oil consumption and operating temperatures.

A low viscosity, synthetic formulation designed to amplify both the life and performance of your vehicle!

Light enough for an import - Tough enough for a semi. Use in new equipment which requires synthetic oils or any equipment that needs enhanced performance.

Craig Michelson uses Lucas Heavy Duty Oil Stabilizer for 1942 M-7 Priest Sherman Tank

My name is Craig Michelson and I am the curator and vehicle maintenance coordinator for American Heritage Park in South El Monte, California. We have over 140 vehicles from World War I to present. The museum has in its inventory a 1942 M-7 Priest which is basically a Sherman tank with the top cut off and a 105mm gun installed. This particular vehicle has a nine cylinder, 975 cubic inch aircraft style radial engine.

Before starting radial engines the motor has to be hand turned to make sure the bottom cylinders do not fill with oil and cause a hydrostatic lock.

About a month ago we used Lucas Oil Stabilizer in our last oil change. This morning the mechanics turned the engine with the hand crank and noticed it started with less effort. After it started there was less smoke coming out of the engine during the warm-up. This is proof to me that your product does what it claims to do.
