HEAR IT FROM OUR CUSTOMERS

Timothy E. Wright a US Marine Only Uses Lucas

I don't know your secret, but it sure does work. Every time any fluid gets changed in my 1999 Jeep Grand Cherokee, Lucas Oil is in it! I think your product is outstanding and I recommend it to everyone I know and meet! Thank you for a great product.

David Uses Lucas products in ’60 Falcon with 400k Miles

I am the owner of a 1960 Falcon, with 400,000 miles. I recently added 3 of your products to my engine, transmission, and fuel system. Please know that my vehicle now runs better than when it was relatively new!!! Really amazing products. You saved me a bundle of $$$ and heartaches. Now it's a pleasure driving my car.

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 The Lucas Oil Stabilizer and There Was an Immediate Result.

I have always had a loud top end on my Harley Sportster. And ever since I started using this oil [Lucas 20w50 Motorcycle Oil], my engine is quieter and have noticed much better my motorcycle is running overall. I added the Lucas oil stabilizer yesterday and there was an immediate result. I LOVE Lucas products and as a motorcycle mechanic for Harley Davidson, I tell everyone I know with Harley’s to use this oil. -
