2003 F150 5.4L Triton 3-valve. Timing chain, guides and cover had disintegrated at about 280,000 and constant oil leakage. Put new chain, guides, oil strainer, pick-up tube etc and drove to 345,000 using 20w50 and losing about 2 quarts a month. Noisy upon start-up which I understand is typical for these Tritons plus lifters made constant noise. Was about to install a new/used motor when I figured what the heck try a bottle of Lucas hi-mileage stabilizer. IMMEDIATELY quieted engine and after adding another bottle a week later, engine is running QUIETLY!!! leaks less too. Have installed new coil packs and I think this 5.4 might just make it to 500,000!! I also added 1qt to the tranny…shifts smoother.

I have always had a loud top end on my Harley Sportster. And ever since I started using this oil [Lucas 20w50 Motorcycle Oil], my engine is quieter and have noticed much better my motorcycle is running overall. I added the Lucas oil stabilizer yesterday and there was an immediate result. I LOVE Lucas products and as a motorcycle mechanic for Harley Davidson, I tell everyone I know with Harley’s to use this oil. –

My son’s 2005 VW GTI with the 4 cylinder turbo and 127K miles on it sounded like there hammers inside the engine. The car was close to needing a oil change so I bought a quart of High Mileage Oil Stabilizer. He changed the oil adding the stabilizer started it up and we took it for about a 8 mile drive. When we got out of the car we noticed right away that almost all of the noise was gone! He has a 200 mile drive back to school in a few days and I’m willing to bet all of the noise will be gone by the time he gets back to campus. Thank you for a great product!

I own a 2001 Chevrolet Tahoe it has 230000 miles on it. I also own a 1995 Chevrolet Truck with over 225000 miles on it. I have used Lucas Oil Stabilizer in them both for the last four or five years. This stuff is AWESOME my oil pressure stays between 55 to 65 lbs very consistently. I use a variety of other products in the LUCAS OIL line gear oil, grease, fishing reel oil, gun oil and Slick Mist. Keep up the good work LUCAS OIL your products are AMAZING!!!!!!!!!

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.

Actually from Canada but get down to Texas. I have a 1995 Dodge Grand Caravan with a 3.3 litre engine and 4 speed transmission with 200,000 miles. Doesn’t burn oil and the tranny is good and said I would keep it until one of those gave out. We took a 1,500 mile trip last month with it in the mountains towing a trailer with a ton of furniture to my son’s new home. Lucas oil treatment saved the engine from overheating when we went up passes. When the tranny started to clunk, clunk badly Lucas transmission treatment got us home. And it is still going. Unbelievable.

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.

I maintain a fleet of equipment for a local golf course use Lucas Oil Stabilizer in all of the equipment. One of our spray rigs hit a tree stump and cracked the oil pan in half. The operator didn’t realize how bad it was leaking and drove it 1/4 mile back to the shop! I pulled the bottom rotating assembly apart and was totally amazed everything was fine. If it wasn’t for the Lucas being in there it would have froze up for sure! I am a true believer in this product as I use it it all my own personal vehicles along with my 850h/p drag car!
