I have an 85 Celica and the fourth piston would always knock and I would use Mobile 1 Full Synthetic everytime I would do an oil change and I never thought to use lucas well someone told that would shut up the knocking in the fourth piston well I gave it a try used 3 QTS of mobile 1 full synthetic and dropped one quart of the oil stabilizer and the knocking stopped before I even dumped the whole bottle in I am a now a Firm Believer in Lucas I also used the Powersteering stop leak and it has not leaked a drop of power steering in over a month. I now also use the fuel treatment with every fill up and I went from 21 mpg to 30 mpg and my engine has never run so well.

AS A OVER THE ROAD TRUCK DRIVER I HAVE USED THE HEAVY DUTY OIL STABILIZER IN MY TRUCK AND WAS SO HAPPY WITH RESULT'S THAT WHEN I ORDERED MY FRIST NEW 2005 CADILLAC DEVILLE LUCAS SYNTHECTIC HAD JUST CAME AVAILABLE AND I USED AT IT'S FRIST OIL CHANGE AT 3000 MI. WITH SYNTHECTIC OIL CHANGE AND KNOW WITH OVER 55,000 ON THE CLOCK IT JUST AS SMOTH AS IT WAS WHEN NEW. JUST TAKE THE OIL CAP OFF AND LOOK INSIDE CLEAN AS THE DAY IT WAS MADE. IT'S POWERED BY LUCAS.

I've been driving my 1987 Chevrolt Camaro Berlinetta for 4 years now. I bought it at 150,000 miles, they told me my cam bearings might be shot. After using Lucas Oil Stabilizer at every oil change, and the Upper Cylinder Lubricant once a month, I get 50 miles per gallon highway and my car is going strong at 260,000 miles. Lucas is a key component in my equation for better gas mileage, and my enigine wouldn't be doing half as well without it.

My car had a terrible engine knock. I shuttered to think how much it would cost to get it fixed. At my local auto store your stabalizer was showcased at the checkout counter. Skeptical at first, the promise written on the bottle made me ask does this really work. Well, I changed the oil and added your stabilzer first. The difference was remarkable. My car runs like new. Thank you for such a wonderful product.

I put some Lucas synthetic additive in during my normal synthetic oil-change for the the engine and differential and got 30.8 miles to the gallon!! The rear axle is silent now, too! The engine idles quietly. I'm impressed with how smooth the power is now. Thank you Lucas Oil for enhancing my conventional synthetic oils!!

Hello, my name is Tim Slatkavitz and I am not the type to write to a company abouth their product but I felt compelled to. During the first week of June I was on the Hot Rod Power Tour which started in Cleveland Ohio. On the drive to Cleveland from Massachusetts my car developed an oil pressure problem. Once in Cleveland I had to replace a lifter and I changed the oil but still had oil pressure issues. A friend told me to use Lucas oil addative, I have never believed in them, but I have to say Lucas worked. The car made it all the way from Cleveland to Little Rock then back to Massachusetts. I will now be adding Lucas to the rest of my vehicles. Thanks for a great product.

I used it and can tell the difference i get about 10 miles more to the mpg horespower thank you so much and i use the oil stabalizer works really really good even more power thanks that helps withgas thanks again for your product

I had stopped using your product after replacing a clutch at 192k miles on my Nissan Maxima. I honestly didn't think there would be any difference! It started to burn oil at a high rate and I had to start adding half a quart every 500 miles. At the next oil change, I switched back to Lucas and have not had to add any oil between regular intervals since then.

I have always used Lucas products in my race cars for the last seven years,and every tear down it still looks brand new. Thanks Lucas

I HAVE RACED TQ MIDGETS FOR THE PAST 16 YEARS. I STARTED USING THE SYNTHETIC OIL STABILIZER IN MY ENGINES IN 2004. WE USED TO REBUILD OUR ENGINES EVERY 6 RACES. SINCE USING YOUR PRODUCT WE RACED 23 TIMES IN 2004 WITH NO ENGINE REBUILDS. WE WON THE 2004 CHAMPIONSHIP WITH THE SAME MOTOR ALL YEAR. WHEN WE DID TEAR IT DOWN IT LOOKED LIKE IT WAS BRAND NEW! NO WEAR WHAT SO EVER! WE SIMPLY CLEANED IT AND PUT IT BACK TOGETHER. WE SAT OUT THE 2005 SEASON DUE TO SURGERY BUT CAME BACK IN 2006 TO WIN 8 OF 10 FEATURES ON OUR WAY TO THE 2006 CHAMPIONSHIP WITH THE SAME ENGINE. NO TEAR DOWNS AGAIN UNTIL THE SEASON WAS OVER, AND AGAIN NO WEAR ON THE BEARINGS OR ANY ALUMINUM SURFACES. AFTER LETTING MY SECRET OUT ON MY ENGINES YOU NOW HAVE ALMOST EVERY COMPETITOR IN OUR SERIES USING YOUR PRODUCT. THIS IS THE REASON THAT MY CARS WILL NEVER GO WITHOUT YOUR PRODUCTS. THANK YOU TRACY HULL
