Heavy Duty Oil Stabilizer

A pure petroleum multi-use oil supplement. Controls noise, heat and wear in manual transmissions and differentials. Number one in the heavy duty and high performance industries.

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. Use Lucas Oil Stabilizer in gear oil to stop leaks, reduce operating temperatures and increase the life of the gear oil. Since it is pure petroleum, it can safely blend with all other automotive lubricants, even synthetics, ATF and mineral oil. It keeps old engines alive and new engines new.

In Ford Powerstrokes we suggest one quart of Pure Synthetic Oil Stabilizer per oil change.

Lou Lealer uses Lucas Heavy Duty Oil Stabilizer for 1989 Toyota supra non-turbo


I am the proud owner of a 1989 Toyota supra non-turbo. In December of 2001, I left Erie, PA on a trip to the Florida Keys. At this time I did not have Lucas Oil Stabilizer in the vehicle. I averaged 20 miles to the gallon on a round trip. Again in February, I took a trip to West Palm Beach, this time with your Lucas Oil Stabilizer in the crankcase. Not only did I gain 12 to 15 pounds of added oil pressure, (six to eight psi at idle) I gained 8 to 10 mpg as well as a definite change in the gain in performance from the engine and a smoothness in the idle of the engine.

On the first trip I consumed two quarts of oil 20/50 wt. On the second trip the consumption went down to one quart of oil over three thousand miles in fourteen days. I have become a firm believer in your product and have related my success to several of my friends who now use your product as well.

Thank you for formulating this product and know that you have several new believers in your excellent product. I am now trying your Power S teering Stop Leak and Transmission additives.

I'll keep you posted.
