HEAR IT FROM OUR CUSTOMERS

I am amazed at what it has done to my engine noise.

I own a 2008 Ford F`50 with a 5.4 engine and 137,000 miles. Over the past year my engine developed the Ford death rattle. It's known as cam phaser problems. This was when pulling a trailer at low idle. I decided to try out Lucas High Mileage Oil Stabilizer additive.T his was 12,000 miles ago, and I am amazed at what it has done to my engine noise. It's been gone since a week after I started using it. I told my son in law about it, as his Honda engine is using oil and fouling plugs. He is amazed at how it has helped his engine trouble and he has not fouled a plug since he started adding it.
I also have added it to my old Briggs and Stratton 5 hp engine. It smokes really bad, since adding it has cut it down 80 percent. It has made believers out of us. Thanks

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!

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.
