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.

Whether I’m chasing Trophy Game animals or chasing Trophy Fish Lucas Products are running with me

My name is Jim Klinkner the owner of Klinks Premium Wildlife Blend. I'm a firm believer in Lucas Products. I use Lucas Synthetic Outboard Marine Oil in my Bass Boat and I use Lucas oil in my ATV's. I depend on Lucas Products whether I'm chasing Trophy Game animals or chasing Trophy Fish Lucas Products are running with me. My machines seem to love Lucas Products better than the rest. Less plug fouls, less smoke the machines running better and smoother. Thanks Lucas

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!

It helped my 2003 Mazda MPV van perform better.

Came to your site and found out about Complete Engine Treatment, so I got some of that too!! It helped my 2003 Mazda MPV van perform better. Thanks much.
