HEAR IT FROM OUR CUSTOMERS

I’ve been using Lucas Products for my vehicles for many, many years now with complete satisfaction.

I've been using Lucas Products for my vehicles for many, many years now with complete satisfaction. I came upon their gun oil many years back while at my local auto parts place while still living in California. Been using it ever since while all the other products I have collect dust.

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!

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!

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.

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.
