98 or 95 Ron

[Gazza747]

I'm sure my filler cap says minimum 98 RON!

Yeah mine does too. Although I think on later Gti's they changed it to 95. I have heard of head gasket problems on Gti's running long term on 95, but I don't know if that is only early cars or not. Personally I have always used super, get better mpg and feel.

I have an 07 plate Gti and it states 95 ron on the filler flap. In the instruction booklet it states "There will not be a gain in fuel efficiency or power with a higher ron fuel". I get around 40mpg on my 36 mile commute with 95 ron so the efficiency is pretty good. If I had an earlier Gti or ED30 or map to 99 ron I would use the highest ron fuel available.

I tend to only use Momentum the slightly better mpg over a tank just about justifies the extra cost. Works out to be about the same mile/£ for me
