Question: What oil do Nascar engines 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 weight oil do Nascar engines use?

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.

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.

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.

What kind of oil do race engines use?

The most common type of race oil is a 10W-60 viscosity grade based on a Group IV full-synthetic PAO base oil blend. However, there are many base oil mixtures possible.

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.

What makes a Nascar engine so powerful?

The answer is actually quite simple: Subject the engine to lots of heat and pressure. … NASCAR engine parts are heavily reinforced to protect against these extreme conditions. In other words, they’re bigger, stronger and thicker than their counterparts would be on a less powerful car.

What is the best oil for high performance cars?

  7. Liqui Moly Synthoil Premium.

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.

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.

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.

Which oil is better 10w30 or 10w40?

The difference between 10W-30 and a 10W-40 is the high temperature viscosity. Obviously, a 10W-40 is thicker than a 10W-30 at high temperature. … Using the correct viscosity oil eases starting, reduces friction, and slows wear.

What oil is better for performance?

Synthetic oil is by far better for performance. It protects the engine due to lower levels of friction. Additives help clean the engine of deposits. And, fewer impurities mean it burns cleaner, thickens far more slowly, and has fewer deposits to start.

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.
