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

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.

In 2 days my steering is back to normal. Honest.

My '06 Ford Freestar was gradually getting harder to steer. No leaks and a tight belt so no slipping. I emptied as much fluid as I could and added a bottle of Lucas Power Steering Fluid and Conditioner which the bottle says eliminates hard spots.. in 2 days my steering is back to normal. Honest. It worked for me and its been 3 wks now. A garage near me gave me a price of $569.00 for a new rack installed. I lucked out. For $10.00 a bottle it was worth a try. I'm very happy.

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.

I’ve been using Lucas Products for my vehicles for many, many years now with complete satisfaction.

I've been using Lucas Products for my vehicles for many, many years now with complete satisfaction. I came upon their gun oil many years back while at my local auto parts place while still living in California. Been using it ever since while all the other products I have collect dust.

AMAZING PRODUCT!

My family has used Lucas oil additive for years, from our vehicles to our semis. After hearing several opinions from others, as well as my own family, my boyfriend decided to give it a try. He is a die hard Lucas believer now! Earlier today he had an issue of his oil filter failing on his truck and causing most of the engine oil to spill out. We went essentially a mile before the oil pressure gauge started to drop & he coasted it onto the side of the road. The oil that was under the truck was a tackier feeling than before when he didn’t add the Lucas Oil Additive. While we sat on the side of the road he exclaimed “Lucas has my business forever. Their oil additive just saved my truck!
