Whats the difference between Regular Unleaded gas and Premium Gasoline and there is like a supra at like hoilday gas stations not sure whats it called at SA.
are you seriously asking this???????????????????????
yea. what happens if i put the wrong gas in the tank. my sister has a pontiac g6 and hers take preuim
the difference in fuel is the octane levels.
If you read up on threads, there's a lot of different opinions on this. My G37 takes premium, and I've never thought twice about putting a lesser octane in. Why starve your engine of its full potential to save ~$2- per fill up?
You see that number next to the octane rating?
Make sure that number isnt smaller then the number your owners manual says to use and your good.
