AMSOIL DOMINATOR® Synthetic 10W-30 Racing Oil (RD30) provides superior performance and maximum protection in high-performance and racing applications. DOMINATOR is engineered from advanced synthetic technology to better withstand the elevated rpm, high temperatures and shock-loading common to racing applications.
What is the best motor oil for racing?
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.
Is Thicker oil better for racing?
Thinner oils require tighter bearing clearances to maintain oil pressure, but they also reduce friction to free up more horsepower. … For higher temperature applications (such as endurance racing in hot climates), a heavier multi-viscosity oil is usually recommended (something like a 15W-50 oil).
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.
Will thicker oil damage my engine?
Not only that, but the engine will waste energy pumping the thicker motor oil, reducing fuel economy. Since thicker oils don’t transfer heat as well as thinner oils, operating temperatures will increase, too, possibly leading to accelerated chemical break down and harmful sludge and deposits.
Is Mobil 1 better than Castrol?
If you are looking for better preservation qualities, Mobil 1 is generally a better choice than the Castrol Edge. But for conventional motor oils, Castrol Edge’s magnatec additives make it the better and more suitable choice.
What happens if I put 10w40 instead of 5w30?
If you use 10-w-40 instead of 5-w-30 specified by the manufacturer then the viscosity of 10-w-40 used by you will be higher and oil thicker than what is specified during winters. Similarly the oil viscosity will be higher and oil thicker than specified during summers.
What happens if I use 0w20 instead of 5w30?
0w-20 is simply a different viscosity of oil. It won’t be an advantage to your engine if your manufacturer suggests you use 5w-30 and may indeed be a detriment to your engine. 0w-20 may be a recommended oil for certain conditions for your engine and may not be recommended for your engine.
Do high mileage engines need thicker oil?
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.
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.
Do oil brands matter?
No. Switching brands is not harmful to your engine as long as you choose an oil marked with the API donut of the same level, e.g., API SN. … You may give up enhanced performance if you switch from synthetic or high mileage to conventional oil. MYTH: When motor oil becomes dark, that means it’s time to change it.

What oil do Nascars 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.
Does high performance oil make a difference?
With one high-performance car test with a leading synthetic oil, torque improved by less than 1 per cent and horsepower was up around 1.5 per cent. Fuel efficiency gains were better – up nearly 1 mile per gallon.
What’s the difference between racing oil and regular oil?
Racing oil contains additives designed for high speeds, not for ordinary driving. … Racing oil contains three times more antiwear and friction reducing additives (for less wear and more horsepower) than ordinary oil.
