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.

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!

Whether I’m chasing Trophy Game animals or chasing Trophy Fish Lucas Products are running with me

My name is Jim Klinkner the owner of Klinks Premium Wildlife Blend. I'm a firm believer in Lucas Products. I use Lucas Synthetic Outboard Marine Oil in my Bass Boat and I use Lucas oil in my ATV's. I depend on Lucas Products whether I'm chasing Trophy Game animals or chasing Trophy Fish Lucas Products are running with me. My machines seem to love Lucas Products better than the rest. Less plug fouls, less smoke the machines running better and smoother. Thanks Lucas

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.
