L9 Racing Gear Oil

Gear oils have needed improving for years, especially in the hi-performance industry. The Lucas L9 Racing Gear Oil provides excellent thermal stability and longevity throughout the entire drive train system. Recommended for use in both transmissions and differentials, Lucas specifically developed this formula with special anti-wear agents and lubricity agents to control wear and drag as well as special additives to control heat. This feature is not found in ordinary gear oils. This gear oil is both excellent for race cars and any heavy-duty application where plain gear oils just aren't good enough.

With the use of our own gear box dyno and feedback from a major IRL Team, we have created these light weight friction free gear oils. They have already won in IRL, NASCAR, Pro Stock Car, Pro Stock Bikes and more. The new technology we developed for these gear oils will now be used in all Lucas Gear Oils.

Key Benefits

  • Perfect for super speedways
  • Increases usable horsepower to the ground by reducing drag and friction
  • Contains special anti-wear and lubricity agents
  • Special synthetic base stocks
  • Very thermal stable

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

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.

There is simply no better products

As a kart racer I can not say enough about the quality and performance helping standards of the Lucas Oil Products. We have been using Lucas Oil Products in our kart for four years now and there is simply no better products. We race all over the southeast and people are always coming up and asking what we are using and how it is performing. Thank You Lucas Oil for your support and your awesome oil products.

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.
