Fuel Question

[MINI-Bob]

Hi,

Hope this isn't a really stupid question but as a newbie i can't see the answer anywhere else on the forums ...

What octane fuel should you run an MCS on? Should i be using Shell Optimax/other Super Unleaded or will regular Unleaded cut it?

Cheers

A standard MCS will run fine on regular 95 octane unleaded.

However, a lot of pople choose to run them on 97 to 99 octane unleaded and some are convinced it makes a difference.

If the standard engine is tuned to anything other than JCW spec, most aftermarket tuners recommend (or insist) on higher octane fuel. GT Tuning certainly insist.

PS: I compromise and run mine on Sainsbury's 97 octane super unleaded.

Thanks Tigger.

It's a standard car i'm looking at, but just checking i'm not missing something obvious.

No problem.

BMW specify that all of their production cars are designed to run on 95 octane unleaded. It doesn't stop a lot of us running something of a higher octane number; it certainly doesn't do any harm, but then neither does running 95 octane

Sorted.

PS: Thanks for the welcome.
