The manual says to use 98 RON, but that 95 RON will work fine cos the engine management compensates.

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.

POST 1 / ORIGINAL POSTEROriginal post

As a new-ish owner I wonder if anyone has experience with this. The manual says to use 98 RON, but that 95 RON will work fine cos the engine management compensates. I ended up putting 95 in it the first twice, once accidently, and the second time because I had to, and I've never really noticed any difference. Anyone notice anything?

POST 2Original post

For normal use 95 ron is perfectly fine. Some people swear by Optimax, but I'm not convinced - I think, in a modern road Porsche, the benefits are largely psychological. However, I do use Optimax in my Caterham, on track, where the engine is regularly revving to 7600 rpm. I'm told that, in these conditions, the engine runs marginally cooler with a higher octane fuel.
