Try out the Motorcycle Oil Stabilizer you’ll hear the difference…

My Harley always had the top end tick like most bikes do. So I decided to purchase the Lucas Motorcycle Oil Stabilizer. Wow I can't believe how much this has helped granted it's still makes noise but it dampens it down alot! I run Lucas Synthetic 20w/50 in my motor with Lucas Gear Oil in my trans. And Lucas primary oil. I don't care what anybody says Lucas makes some great oils! Try out the Motorcycle Oil Stabilizer you'll hear the difference it made a believer out of me and it will you too!

Lucas hi-mileage stabilizer IMMEDIATELY quieted engine

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.

Now the engine is “humming” like it was brand new.

Complete Engine Treatment added to engine oil eliminated squeaking from engine during ignition and now engine is "humming" like it was brand new. 2003 LEXUS RX 300 108K.

I added this to the gas and was amazed… it stopped making the sound that I thought was a rod bearing.

My truck engine has over 200,000 miles and a knock started and I thought it was a rod bearing. I was reading the label on the product Complete Engine Treatment and the words, (stops engine knocks.) I added this to the gas and was amazed, and still am, it stopped making the sound that I thought was a rod bearing. I do have to add the treatment to each fill up, but it does work.
