I love LUCAS OIL

I have used nothing but Lucas Oil since I was younger. I've always seen improvements in every vehicle I've drove or recommended to use. The boost of mpg's is awesome. I know I'm burning cleaner. And OIL. Whoa don't get me started. Every oil change I supplement a quart. Dry starts gone. Ticking, noise, rattle, tapping........ gives in to the products. I love LUCAS OIL. I will always use it, my kids, family, and friends will too. Especially since they have me do their oil changes.

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.

When we got out of the car we noticed right away that almost all of the noise was gone!

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 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

There is simply no better products

As a kart racer I can not say enough about the quality and performance helping standards of the Lucas Oil Products. We have been using Lucas Oil Products in our kart for four years now and there is simply no better products. We race all over the southeast and people are always coming up and asking what we are using and how it is performing. Thank You Lucas Oil for your support and your awesome oil products.
