There are a few 100 octane spots that I go to for track days and stuff, but I usually use the 91 in my car.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Hey, The inside of my gas door reads a formula and = 93. Im assuming this is for the octane of fuel. I only ever see 91 octane and this is what I use. Should I be using additives or just 93 octane fuel? Will 91 octane damage things. Weird to say coming from turbos where 91 was necessary minimum! Thanks

POST 2Original post

Michael, Did you purchase your white Turbo from Oralndo in Miami? Where in AZ are you at? There are a few 100 octane spots that I go to for track days and stuff, but I usually use the 91 in my car.

POST 3Original post

damn lucky people.... california is only 91......

POST 4Original post

There's a lot of places in the US where 91 octane is the highest available (Colorado's the same way). However, my owners manual (pg 177) states: So there you have it. 91's OK although 93 is preferred. Even 90's OK. The ECU adjusts. - Nick
