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.

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.

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 added this to the gas and was amazed… it stopped making the sound that I thought was a rod bearing.

My truck engine has over 200,000 miles and a knock started and I thought it was a rod bearing. I was reading the label on the product Complete Engine Treatment and the words, (stops engine knocks.) I added this to the gas and was amazed, and still am, it stopped making the sound that I thought was a rod bearing. I do have to add the treatment to each fill up, but it does work.

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.
