Racing Transmission Fluids
How often should you change your racing transmission fluid?
Transmission fluid can last anywhere from six races to an entire season. Inspect your fluid regularly and make a change if the color looks darker or smells bad.
Note: Conventional transmission fluid should be changed more often than synthetic as it breaks down faster in extreme conditions.
Is there a difference between conventional and synthetic racing transmission fluid?
Yes. Conventional racing transmission fluid is made in mineral-based oil that’s refined from petroleum. Synthetic transmission fluid starts out with a mineral base, but it’s highly refined, broken down, and reconfigured for purity. Synthetic transmission fluid doesn't break down as fast when running at high temperatures, ideal for long days on the track.
Can you mix synthetic and conventional transmission fluid?
Yes, you can mix conventional, mineral-based transmission fluid with a synthetic version.
