The oil is a very low viscosity (0w-3 / 0w-8). NASCAR uses a light 0w-20 (KV100 = ~7.5 cSt) with the biggest share being Driven XP2 0w-20. NHRA Top Fuel and Funny Cars use SAE 70.
What brand oil does Nascar use?
Mobil 1 has been the official motor oil of NASCAR since 2003, and to ensure it lives up to the standards of some of the best race teams in the world, ExxonMobil routinely puts its motor oil to the test at its Paulsboro Technical Center in New Jersey.
What viscosity does Nascar use?
Sometimes different viscosity oils and formulas are needed within the same racing discipline. Top Fuel dragsters require 70W while Pro Stock racers run the thinnest oil possible, around 0W-5.
What weight oil do Nascars use?

What is the best oil for racing engines?
What is the best oil to use in racing engines? Professional racers across North America recognize AMSOIL products as the best and most effective available. The number of championships and checkered flags claimed by AMSOIL sponsored racers is testament to the extraordinary performance AMSOIL products provide.
How long does a Nascar engine last?
Most production car engines are designed to last over 100,000 miles. NASCAR race car engines are designed to last one race (500 miles, in the case of the Daytona 500). While the same version of an engine is typically used for an entire season, it is rebuilt after each race.
Why do Nascar engines run so hot?
Papadakis explains that NASCAR engines run at around 290 Fahrenheit, or around 90F higher than a standard road car engine. … This reduces required airflow through the radiator and allows teams to tape larger sections of their grilles shut.
Does Nascar use synthetic oil?
NASCAR synthetic oil is chemically engineered to endure the 500-mile long race, this is characterized largely by oil chemistry formulation, they have additives that are specified by the manufacturer, these additives add a combination of a performance boost in terms of efficiency, protection, and lubrication.
Does thicker oil rob horsepower?
Higher or heavier viscosity oil drives up the oil pressure which in turn makes the oil pump work against a higher resistance. In this vein of thought, the oil pump is ultimately just another horsepower robbing accessory similar to the alternator or water pump.
How hot does a Nascar engine get?
The normal operating temperature for a NASCAR Sprint Cup engine varies among teams, but most run in the 230 to 260 degree range.
Does high performance oil make a difference?
Engine Oil DOES Affect Performance
Wonder no longer. The oil you choose for your car’s engine makes a difference in its economy and power production. … At lower temperatures, engine oils with lower viscosity like a zero weight (that’s the 0W) are more fluid than higher weights.

What’s the difference between racing oil and regular oil?
Racing oils contain ZDDP (zinc dialkyl dithiophosphate), commonly referred to as just zinc, at higher levels. This additive is used to create a protective barrier that helps keep metal to metal contact at a minimum. Regular oils don’t contain as much of this additive because there is less of a need for it.
Is Thicker oil better for high mileage cars?
A: Yes. This is a practical method to improve oil pressure in an older, high-mileage engine. The slightly thicker oil film from the heavier base weight oil — 10W — can help protect worn engine bearings as well.
Should I use thicker oil in an older engine?
For an older, high-mileage passenger car, it is recommended to switch to a thicker viscosity oil, such as 10W-30, when approaching and passing 100,000 miles, to lubricate the engine well for preservation.
Which oil is better 5w30 or 10w30?
5w30 is a great multigrade oil for use in low starting temperatures as well as high summer temperatures. It is also more fuel efficient since it creates less drag on the bearings and moving engine parts. 10w30 is thicker and may provide better sealing capability for older engines.
