i currently own a 2007 ford E 350 cargo van, i am an expediter and i travel all over the country. i am the only owner of the vehicle. i currently use your lucas heavy duty oil stabalizer and your fuel treatment, but i am writing today about your oil stabalizer. I have been putting your heavy duty oil stabalizer in my engine EVERY oil change since the 50,000 mark. and i am telling you, i am GLAD i did. my truck currently has 573,000 miles on the engine, you read that right, thats OVER HALF A MILLION MILES! it is also a gasoline engine NOT a deisel, the engine also has NEVER been rebuilt, it has all the original parts, and i owe it all to your AMAZING products at lucas oil, your product DOES what it says it will do, it EXTENDS the life of my engine, and thats exactly what it has done.

I first used the oil stabilizer on a cummins diesel with nearly 700,00 miles and low oil pressure at idle, hoping it would delay an overhaul. It had 960,000 when I sold it and did not need an overhaul. I then used itat every oil change in a Ford 5.4L v8 gas engine with 40k when I bought it. Sirs, it now has 230,000 and barely a quart low at the 5,000 mile oil change. I will now start using the synthetic stabilizer in the 2.0 Ford gas engine in the 2001 Focus I just bought

I have a 1984 Toyota 4x4 with around 184,000 miles that is used for work and play. During every oil change, I substiitute one quart of Castrol with a quart of Lucas Heavy Duty Oil Stabilizer. My wife was driving it home one evening and the oil light came on due to the timing cover seal blowing. She drove it another 4 to 5 miles home and the truck never missed a beat even though there was only 1/2 quart of oil left in the oil pan. I firmly believe using Lucas saved the engine. Great products! Thanks! Dan

I have used your gasoline treatment and your engine oil stabilizer with remarkable results. I now have 264000 miles on my truck and it still doesn't use a drop of oil between oil changes. I also use the gasoline treatment and I'm totally impressed with it.

Just bought a 2005 dodge 3500 with a cummins 5.9...had it 3 days, and already have lucas in the oil, and fuel...will soon have it in both diff's...i am a firm believer in lucas products....thanks for great products! mick armstrong

Just wanted to write and say thank you for making products that actually do what they say they will. I bought an old (1996 Dodge Ram) with 160,000 miles on it. The first week I had it, the oil pressure would drop to zero at idle and the light would come on. I thought I was in for some big money right away. A friend of mine that is a mechanic said to change the oil and use two quarts of lucas heavy oil stabilizer. I thought it was worth a try since he is a very trustworthy source. Guess what, The guage sets on 20 psi at a stoplight with AC running and on 40 psi when driving at normal speeds.

Thought you might like to know that my brother's 2004 Dodge with the Cummins Diesel has approximately 1,100,000 miles on the engine. We are not sure about the exact mileage because the odometer stopped when the engine went to 999,999 and it's still there. We have used Lucas oil treatment faithfully throughout the life of the engine. Further we put over 500,000 on the manual transmission using your transmission additive.

I am writing to express my appreciation for your product. I own a 1999 GMC Yukon. Ever since about 180,000 miles I have been using a quart if your oil stabilizer vith 4 quarts of Valvoline at each and every oil change. It now has 420,000 miles and shows no sign of giving up. Original motor and I only have to add any oil between change if I get past 3,000 miles. I belive your oil stabilizer is a big part of the reason this vehicle is still going strong! Thanks! And my hats off to the Lucas NHRA racing team.

HI I HAVE BEEN USING LUCAS OIL STABILIZER IN MY 94 SUBURBAN 1500 FOR A NUMBER OF YEARS IT HAS OVER 217000 MILES ON IT STILL RUNS STRONG. USE IT EVERY TIME I CHANGE MY OIL
