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.

Robert Welk uses Lucas Heavy Duty Oil Stabilizer for 1991 Chevrolet Caprice

Dear folks at Lucas Oil:

About four months ago I came across Lucas Heavy Duty Oil Stabilizer in one of our local Advance Auto Parts stores. I changed the oil in my 1991 Chevrolet caprice wagon with close to 140,000 miles at the time and put in a quart of the product. I don't fail to do the same every oil change now.

The product has already shown me an increase in fuel mileage per gallon, made the engine run smoother and also helped rid a rear main seal oil leak. Tuesday night of this week the thermostat stuck and the engine heat went out of sight on the gauge and the red "idiot light" came on for the first time in the seven years that I've owned the car. I thought I'd lost the engine. Not. thanks to the superior lubricating and protective properties of the Heavy Duty Oil Stabilizer the engine suffered NO damage, and once I got the hermostat housing cooled down, the thermostat unstuck and coolant back into the cooling system from the reservoir, the car drove the remaining four miles home without incident.

The next day the car drove just like always, smooth performance and normal engine temperature. I believe that without the product in my engine I'd be replacing the motor now. My wife's car also has the product in the crankcase and both cars will continue to have it installed EACH oil change.

Thank you,

Robert Welk
