hello
 

Hi, I am Jarombean and I love rx7's. I am currently looking at a 1999 Mazda rx7 type RB S
I am an rx7 purist and am curious about the type of gase to use, Thank you for your support so far.

welcome!

Hello and welcome. Does the owners manual not specify what type of gas? I'd assume premium

thanks, I looked a bit more and found that i do indeed need premium

Not to sound mean, but unless you're more talented than me in linguistics, reading a Japanese owners manual is a challenge. Plus, the rest of the world uses RON fuel octane ratings. Regular gas is 89+ RON, high octane is 96+ RON.

Per tip form ClubLexus (https://www.clublexus.com/forums/sc-...on-vs-aki.html) multiply the RON number by 0.95 to obtain the regular US-spec octane rating.

93 Octane or more is what most turbo rotary guys use.
