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

I Added The Lucas Oil Stabilizer and There Was an Immediate Result.

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. -

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.
