HEAR IT FROM OUR CUSTOMERS

I would recommend Lucas products to anyone with a diesel…

I have been using Lucas products in my 2001 Ford diesel since new with much success, it has over 250000 miles and going strong. I would recommend Lucas products to anyone with a diesel.

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.

Lucas hi-mileage stabilizer IMMEDIATELY quieted engine

2003 F150 5.4L Triton 3-valve. Timing chain, guides and cover had disintegrated at about 280,000 and constant oil leakage. Put new chain, guides, oil strainer, pick-up tube etc and drove to 345,000 using 20w50 and losing about 2 quarts a month. Noisy upon start-up which I understand is typical for these Tritons plus lifters made constant noise. Was about to install a new/used motor when I figured what the heck try a bottle of Lucas hi-mileage stabilizer. IMMEDIATELY quieted engine and after adding another bottle a week later, engine is running QUIETLY!!! leaks less too. Have installed new coil packs and I think this 5.4 might just make it to 500,000!! I also added 1qt to the tranny...shifts smoother.

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.
