Lucas protected my motor for 7 miles without any oil.

My wife was driving my work car a 1998 Buick that had about 145,000 miles. I started using Lucas Oil Stabilizer in it around 75,000 miles at every oil change. So my wife calls me and leaves a voice mail that an oil light has come on the dash and there’s no oil pressure. I was inside at work at the time so this call went straight to voice mail about 15 minutes later I called her back she was already home from her parents house which is about 7 miles away. By this time I’m thinking the motor is junk. Long story short I get home from work that evening pop the hood and check the oil dip stick and nothing is on it so I add oil to try and see what’s leaking and what kind of noises I’ve got. I added a couple of quarts and start the engine thinking it’s going to make every noise possible. Nothing no noise but a very heavy leak from the oil sending unit. I order the part the next day, installed it filled with new oil and the car is still on the road today. That’s been 2 years ago. I’m a believer of your products this car didn’t have the any oil in it but the Lucas protected my motor for 7 miles without any oil, unbelievable. Thanks -Shannon H., Olive Hill, KY

If Lucas can extend it a few more thousand miles, I’ll be happy with that.

2005 Mazda 3 2.3L around 144,000 miles. Changed oil for my GF’s car and noticed some metal shavings in the oil filter housing. Sure enough after changing oil and starting it up, there was a ‘knock’ tick-type noise at idle that got louder as the engine warmed up. It was audible outside and with the windows down. Not so much driving around with the windows up. Oil was oem recommended 5-20. Researched online for quick remedies and decided to try Lucas Heavy Duty Oil Stabilizer. I planned for a 50% mix (2 qts Lucas to + 2 qts 5-20). Drained about 2 qts 5-20 and added the Lucas. Let the car sit half an hour to allow to drain to the pan. First startup was not encouraging, but after a quick drive around the block and a few more minutes idling, the engine actually got noticeably quieter at idle. My mom came by and also noticed it was quieter. I know the engine is probably on its way out due to the shavings, but if Lucas can extend it a few more thousand miles, I’ll be happy with that. -Alan E., San Jose, CA

Just amazed at how well your products help.

Just amazed at how well your products help. I have a 2011 F150 and just hit 700,000 miles on it, though I use both your oil stabilizer and transmission additive. I have had engine work done but my transmission is still all original and still going strong at 700,000 miles. Due to my diligence of changing my transmission fluid and filter every 30,000 or 40,000 miles, as well as an oil change every 8,000 or 10,000 miles, just depends on wether the miles are highway or city. Thanks again for a great product line. Sincerely, Loyal P., Gaston, SC

The engine is quiet right away!

My 2006 Pontiac Vibe has 600,000 kms. Nobody will adjust the valve lash, required in the Owners Manual every 80,000 kms. VVT-i covers this 5 hour job, so the engine is always noisy. I used the Lucas Oil Supplement [Heavy Duty Oil Stabilizer] 1 Liter + 3 liters of 5W30 for this 600,000 km oil change. The engine is quiet right away! Pickup is much better! And I'll be happier in 4 months if the oil is cleaner when I do the next oil change. I will use this Lucas product every 2nd oil change, because it sticks inside the engine. Great way to get 1,000,000 kms! -Nelson H., Toronto Canada

The mechanic said the car runs cleaner than most of the newer cars on the road.

I have been putting your oil additive [Heavy Duty Oil Stabilizer] into my girlfriends 1994 Honda passport for over a year. She took the car to get it a smog test done. Under gritted teeth the car passed the test with flying colors. Not only that but the mechanic said the car runs cleaner than most of the newer cars on the road. This car tested better than the average. I totally attribute this to the Lucas oil additive. Thank you for having a product that actually works better than anything on the market. Believe me when I say I have tried them all but none have compared. Proof is in the smog testing. -Jack D., Lake Havasu, AZ

It had been shifting and going into gear fairly poorly. Not anymore!

I put Heavy Duty Oil Stabilizer in my 2004 F-150's manual transmission with a fluid change. It had been shifting and going into gear fairly poorly. Not anymore! Truck only has 144,000 on the ODO, but I believe it'll just keep going and Lucas is part of my plan. Oil change coming up in a few thousand miles and I've already bought my Lucas! -Travis F., Las Vegas, NV

Wow it runs great now.

Used Heavy Duty Oil Stabilizer in 40 year old diesel tractor. With a quality name brand engine oil. And wow it runs great now. Had a couple of slow seeping oil leaks not bad enough to fix, but now no need. Plan on using more Lucas products as I redo this tractor. Will post more as I go. Have always used Lucas in all my vehicles and I got 250,000 miles out of an old ford engine. Great stuff. -JP, West Memphis, AR

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
