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.

Lucas is SERIOUS about what they sell.

After checking my Power Steering Fluid on my Kia Spectra, I noticed the level was low. Bought the Kia new and its now 4 years old. I decided to drain the rest of the power steering fluid and replace with Lucas Power Steering Fluid purchased at Auto Zone. What a noticeable difference in steering! Price was a few dollars higher and I would spend a few more knowing Lucas is SERIOUS about what they sell. 100% would recommend Lucas Power Steering Fluid.

In 2 days my steering is back to normal. Honest.

My '06 Ford Freestar was gradually getting harder to steer. No leaks and a tight belt so no slipping. I emptied as much fluid as I could and added a bottle of Lucas Power Steering Fluid and Conditioner which the bottle says eliminates hard spots.. in 2 days my steering is back to normal. Honest. It worked for me and its been 3 wks now. A garage near me gave me a price of $569.00 for a new rack installed. I lucked out. For $10.00 a bottle it was worth a try. I'm very happy.

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.
