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

It DOES work. Very happy with your product.

We want to tell you that your radiator additive has kept our engine cleaner than ever. Our Corvette competes in SCA racing and every winter we tear it down and refresh the engine and some other components. From years past, we got used to seeing a brown residue inside the heads, manifold and areas where the coolant passes through. And we also would always see brownish orangish gunk inside the radiator cap. But this year it was spotless! We feel it is because last year was the first full year we ran your supercoolant in our radiator. Now we're telling everyone we can. If you want to keep it clean, pour in a bottle of the Lucas radiator additive. It DOES work. Very happy with your product. Thank you Lucas. -Bill Thomas
