HEAR IT FROM OUR CUSTOMERS

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!

Thank you Lucas Oil for helping me me save time and money!

I have been using Lucas Oil products on the farm since 2001. Since then we have gotten more hours between overhauls in our farm tractors and semi trucks. Thank you Lucas Oil for helping me me save time and money!

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.
