I change my oil every 5,000 miles with synthetic oil and a bottle of Lucas Heavy Duty Oil Stabilizer; and have been doing so for the last 7 years. The other day I pulled into the gas station and filled up my tank, and routinely checked my fluids when I noticed that my engine did not have a drop of oil! I quickly went in purchased (2) quarts of oil and drove home to get my Lucas! I added the Lucas and started the engine and my engine is still running without any problems and I know it was all those years that I had been using your product. I thank God for Lucas and all its products.

Hi, I want to say thank you for your great products. I've been using your heavy duty oil stabilizer for years. Recently I purchased a 2007 equinox. I travel a lot and I was averaging 740KM per tank. My last 4 tanks of fuel have averaged 920KM. You can't imagine how happy I am as the gas prices in Canada are so high.

I bought a 1986 Chevrolet S10 with a 2.5 L. It had a knock since the day i bought it. I found out a connecting rod bearing had spun on the crankshaft. I stared using Lucas heavy duty oil stabilizer from the first oil change. I just used inexpensive motor oil , a new filter and about 200ml of Lucas oil every 5000 km . Well 10,000km later, it's still running . I traveled 800 km to see my parents, hauled heavy loads for a friends and back and forth to work every day. I am truly amazed at this product. I'll keep you posted on my progress with the truck . Thanks, Johnny

I wasn't sure what I was going to do but I had a feeling a lifter was sticking. I didn't have much money to put in it while I was on my trip so I decided to try an oil change and my wife suggested we try some Lucas because she likes to play with the little display they have in the store. Well I changed the oil and added the Lucas Oil Stabilizer. When I started the car right after the change, it sounded just as bad as it did before.... then slowly started to get quieter and quieter... then the tapping just went away.

Hello, I was just wanting to say how pleased I am with your oil stabilizer product. I recently bought an old 83 GMC Sonoma and it was noisy and rattely. I changed the oil in it and used a quart of your stabilizer and it runs much better and isn’t as noisy anymore. It also caused my oil consumption to decrease and my fuel mileage to increase. I just wanna say thanks Lucas. Dave Harris

I pulled the oil pan and sure enough the oil pump drive shaft was twisted a full turn and was snapped in half an inch from where it plugs into the oil pump. I changed out the pump and shaft, looked at the rod and main bearings, and put it all back together. It fired right up no knocking or any other noise. I still cant believe it. When i stopped at Jordan Valley my truck was making death rattle sounds, now you would never know the abuse i put that motor through. I will use Lucas Products in all of my engines, lawn mower, weed eater, whatever, i have told everyone i know what a superior product Lucas puts out. I am a customer forever.

I just wanted to share my story from the King of the Hammers rock/desert race in southern California that Lucas Oil was involved in. We had to replace rod bearings in the engine the night before the 135mile race and had badly scored rod journals on the crank. We used one quart of Lucas oil stabilizer and the engine completed the 135 mile race and is still running with the "temporary" rod bearings in place. Thanks for helping us at the 2010 King of the Hammers event.

I love your lucas oil stabilizer. I have been running demolition derby cars for 9 years. This year my oil filter got hit and my oil went everywhere. We duct taped what was left and thanks to the thickness of this product I was able to run my car for 30 minutes putting me 5th in the main event. I will swear by your lucas oil stabilizer and will continue to use it. Thank you Lucas oil.

knew my little 87 used some oil and leaked some, no big deal, right? Till I checked it one day and the oil was just touching the dipstick, was about 2 qts low only holds 4, so no telling how long it had been low, a friend said it's done to late but I HAD lucas oil stabilizer and 15/40 rotella oil in it and 167,330 miles later the little 4 cyl still keeps on going, wish I'd known about lucas 11 years ago, cause I had a 90 F-150 and it had a leak, long story short, it had to have another motor, and the bad thing was, it only had 75,000 on it had it was almost, paid off, I know if I would've had lucas then it would still have the same motor, live and learn, if you don't use lucas why not start today, might wish you had some, if you tend to keep your auto for a loooon time like I do.

I used to own a 1992 Dodge Grand Caravan, which was used when I bought it in 2005 and had about 115, 000 miles on it. I changed the oil in it and ran the Lucas Heavy Duty Oil Stabilizer in it every time I did an oil change. I also used every fuel up Lucas Fuel Treatment. They both worked well because up till the van was totaled in an accident, I had it over 220,000 miles or so. But the best of your products and the two I always recommend to everyone is the Lucas Power Steering Stop Leak, Lucas Transmission Fix. Reason being for both. The Lucas Transmission Fix was used when I changed my transmission filter, and fluid. Little did I know that in Dodge Transmission that I should have used the ATF +3 not regular ATF.
