I Don't Hear Noisy Lifters After Driving 70 Miles With It

I have low oil pressure in my engine heads which scored the camshafts and cylinder heads on a ford 5.4 liter engine. The ford service advisor said to try a quart of Heavy Duty Lucas Oil Stabilizer with the oil that is in it. I don't hear noisy lifters after driving 70 miles with it, and it doesn't rough idle when the engine warms up at traffic lights caused by the low oil pressure in the heads affecting the vct timing phasers. Hopefully it will extend the life of the heads so I can get a little life out of them before they fail. -John B., Granville, NY

With the Lucas HD oil stabilizer I can go up to 7000 miles without adding any more oil

I drive a 2014 Toyota Tundra with 175000 miles on it. I use the full synthetic oil and change it around every 6000 miles. Around 3000 miles or so I need to add a quart of oil. With the Lucas HD oil stabilizer I can go up to 7000 miles without adding any more oil. I have also use your power steering fluid and transmission additive with unbelievable success. That’s another story! -Harry C., Lima, OH

The best oil product I've seen in my 58 years of mowing lawns

Hmm only 5 Stars?!? Two summers ago, I accidentally overfilled my 19.5 HP BS John Deere mower. It smoked like crazy, so I stopped it, took it to my mower man. He said it had fouled the plug and he cleaned it up as good as he could, it may run 5 mins, 5 weeks, who knows. It still smoked till the end of the summer, however I started using the Lucas HD oil stabilizer and it's been doing nothing but improving. Its now 2021 June 17 and it no longer smokes. The best oil product I've seen in my 58 years of mowing lawns!! I add it to my 2000Ford Ranger, 159000 miles and it runs like new!! You cant give this product enough stars!! -Thomas G., Florence, AL

Great product!!!

I have a 2020 toyota camry and went to my dealer for 1st 5000 mile check up. It was down 2 quarts!!!! Service Manager said to top off with 2 quarts of HD OIlStabilizer, which I did. No oil change as way too early anyway. It ran excellent. I returned for next 5 k tire rotation and oil was exact level. NO loss at ALL. He said even for new engines it is fine to add up to 2 + quarts of the OIl Stabilizer. I went just bought at gallon at Autozone!!!! Again, Thanks for making a great product. I've turned all my friends on to it. NO more oil loss!! -John Meadiris, Marietta, GA

I Highly Recommend Your Product To Everyone

I bought a 96 3500 Dodge RamVan with a 360 5.9 V8 19 years ago with 88k for miles, I've been putting 1 bottle of Lucas Oil [Stabilizer] in it, every oil change. At 470K (two years ago) I lost coolant somehow and ended up blowing the head gasket. I tore the engine down to fix it, I could not believe my eyes when I saw the cylinder walls when I looked at them!! I COULD STILL SEE THE FACTORY HONE MARKS ON THE CYLINDER WALLS!!! I now have 560k that's...... FIVE HUNDRED AND SIXTY THOUSAND MILES!! Not a lifter ping or sound of ANY kind. Thanks Lucas, I highly recommend your product to EVERYONE. -Dean S., Worcester, MA

The Difference to Using Only Oil For The Oil Change is Absolutely Amazing

When I use the 20% Lucas Oil Stabilizer with 3 liters 5W30 in my 2006 Pontiac Vibe the difference to using only oil for the oil change is absolutely amazing. Quieter running engine. Much improved faster pickup with less pushing down the gas pedal. Also stays in Overdrive on uphills easier, and with no effort. This product is the best engine additive I've found in 50 years of driving and working on cars! -Nelson H., Scarborough, Maine

Your Products Are Amazing And I Will Continue To Use Them.

I have been using the Heavy Duty Oil Stabilizer since I bought my 2006 Ford Ranger FX4 in 2005. I use it to replace 1 quart of oil every oil change since the 1st Oil change. During the winter months here in Northern Michigan, I use 1 quart of the Synthetic Oil Stabilizer in oil changes due to our colder temps here. I also use the Complete Fuel System Cleaner every oil change and sometimes a couple times a month. I put in Transmission Fix every time I change the transmission fluid and filter too. I currently have just under 395,000 miles on my Ranger. I have NOT done Any Internal Engine Work. The motor still runs like New and doesn't use any oil from oil change to the next. Your products are Amazing and I will continue to use them. I also have a 2004 Suzuki Vinson 500 4x4 ATV with 11,000 miles that I use oil stabilizer in too. Still runs great. Go Lucas. -Cliff H., Gaylord, MI
