Semi-Synthetic Racing Only Motor Oil

It’s common knowledge that as oil temperature increases, viscosity decreases. The best way to combat this issue is a higher viscosity, thermally stable engine oil that can perform consistently at these elevated requirements. Fortified with ZINC Technology and bolstered with the Lucas Semi-Synthetic additive blend.

Key Benefits

  • Fortified with extra ZINC for severe racing applications
  • Resists breakdown and contamination from exotic fuels such as nitro and methanol
  • Resists thinning out at high crank-case temperatures

HEAR IT FROM OUR CUSTOMERS

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.

Lucas is SERIOUS about what they sell.

After checking my Power Steering Fluid on my Kia Spectra, I noticed the level was low. Bought the Kia new and its now 4 years old. I decided to drain the rest of the power steering fluid and replace with Lucas Power Steering Fluid purchased at Auto Zone. What a noticeable difference in steering! Price was a few dollars higher and I would spend a few more knowing Lucas is SERIOUS about what they sell. 100% would recommend Lucas Power Steering Fluid.

I would rate them a 10 out of 10

I use Lucas lubricants in all my equipment from diesel, gas and 2 cycle. I have never had any issues and my equipment runs and starts lime day one. Lucas is a great product and I would rate them a 10 out of 10 for a quality of product.

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.

Thank you Lucas Oil for helping 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 save time and money!
