Whats up guys! I have a 6mt g37S that i just recently purchased! I love the car, black on black...My question is about the gas...I couldn't find any posts so i figured i'd ask . After a week i had to load the car up with some fuel so i used premium (which is the highest one). I just wanted to be sure if i did the right thing or if it matters?

Thanks guys!

 

Yes, use premium. Some people will say it's a waste of money but the car was made for premium gas so use premium gas. I use 93 but in some places only 91 is available

 

it says in your owners manual to use at least 91.

 

94 (10% ethanol)

 

Ive always gone out of my way to make sure I put 93 oct in my car. sometimes filling up early if I have to.

 

Are you kidding? There are hundreds of threads on this subject. In fact it’s one of the most recurring and may I add tiresome topics that regularly appear on this forum. I know you’re new, but just search “fuel requirements” and you’ll get stuff like this:

And of course there's always the owner's manual that also covers your question.
