I traded that truck in with over 329,000 miles on it, not one problem with the V-10!

I owned a 2000 Ford F-350 with a V-10, when I bought the truck it had 45,000 miles on it. Every time I changed the oil I added 1 quart of Lucas [Oil Stabilizer], along with a WIX oil filter. I also changed the gear oil to Lucas. I traded that truck in with over 329,000 miles on it, not one problem with the V-10! It never used any oil never smoked, knocked, nothing, it ran as good as it did when I bought it. The trick is this, don't fall for the "high mileage" oils and always buy the better oil filters and add Lucas! On a note, I changed my oil every 6500 miles. -Bill H., Tombstone, AZ

One of the best products on the market today.

I have a 2003 Dodge Ram 1500 with a 5.9(360 cui.) that I purchased with a lot of miles on it. It now (as of 4/1/2019) 479,022 miles. When I change oil I always add a quart of LUCAS Oil Treatment [Heavy Duty Oil Stabilizer]. Also have a 1996 Dodge Ram 1500 enthusiasts the 5.9 in it that has 429,000+ miles on it. One of the best products on the market today. -Terry S.

I will continue to use this recipe, great stuff!

Been running 6 qts of Rotella 15-40 with 2 qts of Lucas Oil Stabilizer, changed out a cam with about 40,000 miles on it, and only 3 of the lifters showed a light wear pattern, and the lobes of the cam were still sharp. This was on a healthy 383 Small Block Chevy stroker. I will continue to use this recipe, great stuff! -Scott G., Auburn, ME

Lucas Engine Oil Supplements are one that a consumer will benefit from.

I am a retired Master Journeymen Auto Tech made under the old school way before ASC came into existence. So with this disclosed my expertise & knowledge substantiates this statement: In the majority of cases after market additives are in the most part marketing hype produced by the manufacture. However, there a few that are not. Lucas Engine Oil Supplements are one that a consumer will benefit from. I purchased my 2005 Ford Escape 4wd/3.0L in 2006 with a little over 20K on the odometer. From the date of purchase to present I maintained the following maintenance procedure on oil & filter change: 1st 500 Mi prior to the change add 16oz of Marvel Mystery oil to the engine oil (remember this engine had already 20K of unknown maintenance). This will dissolve both varnish & sludge build up accumulated in city driving (stop & go). 2nd change oil & filter every 2,500 - 3,000 miles. Add Lucas Oil Supplement [Lucas Oil Stabilizer] every other oil change. This would place the additive as being installed at about 5,000 - 6,000 miles. The changing oil & filter this way does not remove the protection on the engine parts. Yes! the old oil has Lucas in it. However, you are basically removing the contaminates in the old oil. As of this date 1/21/19 the Escape has 296,684Mi with great performance. On a special note: If you are not performing consistently scheduled oil &filter change then you cannot expect a Lucas Miracle to correct your bad maintenance. No additive can regardless of its marketing claim. -Mike G., Santa Maria, CA

Thanks for super great product

I have a C1500 with 430,000 miles on the original motor. I started using Lucas oil treatment [Lucas Heavy Duty Oil Stabilizer] at 100,000 miles. The motor has no leaks or burns no oil. Thanks for super great product. -Jim R., Marietta, GA

After a mix of Lucas oil stabilizer the truck has great oil pressure, runs like new, and has approximately 420,000 miles on it.

I started using Lucas oil additive in my 2008 GMC 2500HD 6.0. I had heard many issues with sludge in the oil pan and bad oil pressure when cold. I had bought the truck with 160,000 on it which was clearly hard miles. The oil pressure was not the greatest so we flushed the engine using motor flush and then if you can believe it diesel fuel. After I have run regular 10w 40 oil with a 60/40 mix of Lucas Oil Stabilizer and the truck has great oil pressure, runs like new, and has approximately 420,000 miles on it. I haven't done a thing to the motor besides flushing it and using Lucas. Since then I use Lucas in all 15 trucks we have and all 30 pieces of heavy equipment. I think Lucas makes an great product and it is the first I can remember that called my attention to additives through their old display where you crank the wheels and see the difference. -Joseph K., Plymouth, MA

After 1 treatment of this my problems were gone.

I drive a '03 Ram 4.7l V8 which has 298,000 miles on it. It had the notorious morning tick and burned oil. After 1 treatment of this my problems were gone. Great product. -Alton R., Wichita Falls, TX


I have 3 Dodge Grand Caravans. The first was a Clunker and was on it's last legs so I decided to try Lucus oil treatment [Lucas Oil Stabilizer] in it. I started her up and poured the liquid gold into her and instantly it made it so quiet that I thought it had stalled. I drove that car into the ground and still the engine purred like a kitten. My next Grand Caravan I'd thought I would experiment with it and NOT put any oil at all in it because I had nothing to loose. If she blows up on me...well she blows up, I don't care. I wanted to see how far I could take this experiment....I put about half a bottle of the miracle fluid into her and BAM...the leaks were gone....She ran real smooth. Now this is the part where people don't believe me but I drove that car for 6 more YEARS without a drop of oil in it!!! The dip stick read that not a drop of oil was in it! I'd tell my friends and then would show them. They couldn't believe it. When I got my third Caravan I drove the old Lucus one to the Junk Yard and it still sounded like a new motor!!! Six years without a drop of oil...all I did was every 3 to 4 months I put in about half a bottle of Lucus.....My new Caravan has Synthetic oil and the recommended amount of Lucus in it ... I SWEAR BY THIS STUFF...thanks for listening to my story.... -Rob A. Moncton New Brunswick, Canada

Lucas keeps engines alive.

I have owned my 2003 Nissan Altima 3.5SE V6 since it was brand new. 15 years later and 160,000 miles it still runs like new! Like many cars from that era, these engines would burn oil and the timing chain guide tensioners would break over time. Why pay for an expensive overhaul? Lucas Oil Stabilizer has kept this engine going strong, reduced oil consumption and blow-by, restored torque and reduced dry starts while quieting the timing chain. The engine runs quiet, starts smooth and quickly, and runs like a strong champ. I keep jugs of Lucas in my garage with oil too. Lucas keeps engines alive. Thank you for saving my car and family our hard earned money! Lucas rocks! -Joel M., Milton, OH

I believe 100% that your Oil Stabilizer saved my motor...

Wanted to thank you for your products. I'm an Uber driver and a few months ago I was driving and got a ping for a pick up. On my way to pick up my passenger my drain plug had vibrated out and lost all my oil. I picked up my passenger took them through the Taco Bell drive though and back to the drop off spot. I drove about 13 miles and ran my car for about 45 minutes with no oil. I believe 100% that your oil stabilizer saved my motor that had over 230,000 miles on it. I have driven almost 5,000 miles since this incident and my motor has no knock, no ping and no issues. Thank you. -Jerry S., Holt, MI
