AMAZING PRODUCT!

My family has used Lucas oil additive for years, from our vehicles to our semis. After hearing several opinions from others, as well as my own family, my boyfriend decided to give it a try. He is a die hard Lucas believer now! Earlier today he had an issue of his oil filter failing on his truck and causing most of the engine oil to spill out. We went essentially a mile before the oil pressure gauge started to drop & he coasted it onto the side of the road. The oil that was under the truck was a tackier feeling than before when he didn’t add the Lucas Oil Additive. While we sat on the side of the road he exclaimed “Lucas has my business forever. Their oil additive just saved my truck!

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!

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.

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.
