Racing Oil Tidbits
Race teams use lower-viscosity oil with more friction modifiers to qualify. Then they change to a higher-viscosity oil for the race.
Racing teams go through racing oil at the rate of about 2,130 qts. of oil per car, per season.
In a typical NASCAR race, oil temps can run as high as 320 degrees F.
Pit crews bring about 60 qts. of oil to every race.
Teams analyze the oil after every race. They check for viscosity change, the level of metals worn away, oxidation (indicates how the oil held up to heat) and additive depletion.
