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.

David Doerfler uses Lucas Heavy Duty Oil Stabilizer for Race car, Boat, Trucks


> Big Mike at the local Napa store introduced me to Lucas Oil Stabilizer a couple of months ago and since then I have purchased many of your products for my race truck, personal truck, boat, and wife's car. I ave experimented with most of the different additives on the market over the years but have never been impressed until now. My wife's car a 95 Ford Contour with 120,000 miles runs good but has a death rattle when you initially start it. I changed the oil and added one quart of Lucas Oil Stabilizer, the death rattle is gone and the motor runs smoother than it has in years.

> I drive a 2000 Silverado pickup with 35,000 miles on it, and check the gas mileage each time I fill up. I always get 14 to 14.5 miles per gallon. I added Lucas Fuel Treatment & Injector Cleaner and got 16.9 mpg on the first tank and then added it to the next tank and got 17 mpg. I did not add any to the 3rd tank and my mileage dropped down to 14.6 mpg. Even after purchasing the Fuel Additive I actually save over $3.00 each time I fill up.

> There is nothing wrong with the power steering in my pickup but I added 8 oz. of Lucas Power Steering Stop Leak just to see what it would do. I started the truck and backed out of the driveway and immediately noticed that the steering was smoother and easier to turn. My next test will be on the Ford Contour's transmission using Lucas Transmission Fix, it slips a little when it shifts. Future test will be on the chain saw using Lucas Chain Lubricant and Semi-Synthetic 2-Cycle High Temp Racing Oil. I do have a couple of questions that I hope you will answer.

* On your product specification sheet for the Lucas Fuel Treatment it states that the 5.25 oz. bottle treats approximately 20 gallons (I think it states 25 gallons on the bottle). Also the same sheet states that the 32 oz. bottle treats 100 gallons. So using these numbers 1 oz. treats somewhere between 4.76 gallons and 3.1 gallons. What is the optimum ratio to mix this at?

* My race truck has a posi-track rear end, if I add Lucas Oil Stabilizer to it will it hurt it? Which fluid would you suggest for the rear end? I run a turbo 350 automatic in it should I add Lucas Transmission Fix and if so how much? >

Thank You for making such great products, I tell all my friends and family to use your products. If you have any more literature than what I have found on your website please send it to me, I would be very interested in reading it. > > >
