HEAR IT FROM OUR CUSTOMERS

It was like riding a completely different bike.

I have a 2008 Harley Dyna Street Bob which has been completely customized to include engine work, custom exhaust and multiple dyno tuned sessions. The motor has 31k miles on it. The engine has always run extremely hot and destroys any oil thats in it in less than 2000 miles. This past weekend, I decided to switch over and try Lucas Oil and added 6 oz of Motorcycle Oil Stabilizer to the fresh oil. The bike is extremely quieter now (always had a sewing machine noise) and runs significantly cooler. It was like riding a completely different bike. I am sold. This stuff rocks.

Bill H Loves Lucas Oil Products!

I love lucas oil products and have been using them for years. The real proof for me was when i replaced my valve covers - the old ones sat on in the garage for months and still had a thick coat of oil on the vertical surfaces!! Goodbye dry start-up!!

Randy’s 1984 Pontiac has over 500,000 miles with Lucas Oil Products

I am writing to you to thank you for your products and the impact it has had on my vehicle. In 1985 I purchased from an employer a 1984 Pontiac Parisienne that needed to have the engine replaced. I have faithfully used Lucas products in this vehicle since that time and have over 500,000 miles on the engine at this time. I get excellent gas mileage and the vehicle never burns or uses oil. While the car may look its age on the outside on the inside it has never wavered. Every time I start it up and drive it is true and dependable.

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.
