Can you use race fuel in your street car?

Answer 1

Many do, but they have highly modified engines, to use racing fuel in a stock or standard engine is a waste of money, manufactures design most engines to run on regular gas (97 octane), compression determines what octane should be, as a rule of thumb.

Answer 2

yes you can put race fuel in your truck. however if the truck is computer controled you must use only unleaded racing fuel. also if you do purchase race fuel, have your computer remapped to produce the most amount of horsepower and torque as possible.

Answer 3

I'm not sure what "race legal" means but race cars typically use higher octane fuel such as 102 and up. Street legal cars use fuel commonly available at the pumps. Depending on the state you're in you'll find anything from 87 (low octane) to 92 and up (high octane). The difference between the octanes rating is the tendency for pre-detonation. High horsepower race engines have high compression ratios and need a fuel that wont ignite before the compression cycle is done.
