This product gives me the fastest ring seal of anything else I have used.

Steve M., Cridersville, OH

I have built vintage and old tractor engines for over 60 years. I have broke engines in on everything from 10w straight weight to s3 diesel oil. This product [Lucas High Zinc Engine Break-In Oil] has so far on dyno break in of flat head Fords give me the fastest ring seal of anything else I have used. I'm not a snake oil fan so if a product passes my tests my customers will hear about it.

Your Stabilizer Is The Best Stuff Ever!

Rodney

Your oil stabilizer is the best stuff ever. It makes the engine run smoother. I have it in my lawnmower with an E3 spark plug and it very smooth running and doesn't vibrate like crazy like it did before with the old oil that i had in it.

I used Lucas Oil Stabilizer for some time in a few vehicles. The vehicle I have now I purchased it as a work vehicle from a salvage yard with 99,000 miles along with the Lucas Fuel cleaner the engine purs like a kitten. I also use the Lucas Power Steering additive and again no problems with the power steering pump the vehicle now has 140,000 miles. I am sold on this product.

I truly believe in your products especially the Oil Stabilizer.

I just want to say I truly believe in your products especially the Oil Stabilizer. I have a 2000 Ford Explorer Sport and it now has 302,264 [miles]. I use a bottle of it at each oil change and I believe it is the reason why it is still running and in good order! Thank you.

95 Honda Accord Rolls Over 300,000 with Lucas Heavy Duty Stabilizer

Chris N., MA

My 1995 Accord just rolled 300,000 miles last week thanks to Lucas Oil Stabilizer which has been part of regular oil changes for years. The engine still runs strong and doesn't burn any oil. I attribute the minimal engine wear to the protection qualities that Lucas Oil products provide. Adding Lucas Oil Stabilizer is a great way to invest in your vehicle's longevity. I highly recommend Lucas to everyone who cares about their car or truck.

After 30 Miles The Rough Idling Subsided

Henry G., Lawrenceville, GA

At 65 years old not much surprises me. I have NEVER used additive in an auto. I have a 2012 Hyundia Genesis with 209,000 miles. It was idling rough. I'm thinking I need a $300.00 cleaning at the dealership. I decided for once in my life I would try an additive. I went to Walmart and of course they had 50 different kinds. I pick LUCAS because they are very reputable company. OK let get to the meat of this story. I put 6 oz of LUCAS UPPER CYLINDER lubricant in my tank. My hand on a bible after 30 miles the rough idling subsided. I would not believe this if it had not happened to me. Jaw dropping moment.

Really has made a difference in the performance of the engine

Gordon W., South Burlington, VT

I have been using your upper cylinder lubricant in my 2014 Camaro since it was new. Really has made a difference in the performance of the engine. Not to mention that it helps keep the intake, injectors and the valves clean. One of the best things you can do for your engine. Lucas products are the best out there and a great value too.
