Racing Only Motor Oils
What’s the difference between racing oil and regular oil
Racing oil is designed specifically for the increased demands of
racing engines. The type and amount of additives in its formulation
are tailored to provide additional protection against wear and
extreme heat common to racing engines. Boosting additive content in
these areas doesn’t leave room in the formulation for sufficient
levels of additives that passenger-car/light-truck motor oil
requires, such as friction modifiers to improve fuel economy or
corrosion inhibitors to fight corrosion throughout longer drain
intervals. While racing oil is designed to excel in extreme
conditions over a relatively short drain interval,
passenger-car/light-truck motor oil must excel in multiple areas
throughout longer drain intervals.
Why do racing
engines need specialty oil?
The powerful, modified
engines in racing vehicles produce extreme heat and pressures that
greatly exceed those of the average car or truck engine. A
900-horsepower Pro 4x4 racing truck, for example, produces oil
temperatures in excess of 300°F (149°C). By comparison, the engine
in a typical car or truck might hit 230°F (110°C). Extreme heat from
racing causes motor oil to break down sooner. In fact, the rate of
oxidation doubles for every 18°F (10°C) increase in oil temperature.
Racing engines also produce tremendous pressures between components,
such as the crankshaft journals and bearings, that can shear the
oil’s molecules, reducing its viscosity. For these reasons, racing
vehicles require specialty racing oil, in addition to gear oil and
racing transmission fluid. Racing engines also require properly
formulated assembly lube and break-in oil to achieve maximum power
and life.
Can I use racing motor oil in my car?
Most competitors change oil every couple races, and sometimes
after every race. For that reason, racing motor oil is typically
formulated with a lower total base number (TBN), which is a measure
of its ability to neutralize acids. Motor oils for passenger
cars/light trucks require a higher TBN since they’re changed much
less frequently.
In addition, the motor oil you use in your
daily driver should excel in other areas unimportant to racers, such
as maximizing fuel economy and providing easier cold starts. For
these reasons, it’s best to use a motor oil formulated specifically
for your vehicle and not a racing oil. Find AMSOIL product
