Oh yeah so they do............I was trying to make sense of a few alfa niggles last night on their forum, so didn't look. It did feel different then. No more cheap stuff for me then!!!!

Can we please have an Alfa Romeo section of this forum........

Yep you have

I get ever so slightly better MPG from high octane fuels, but not enough to make it economical compared to standard ones; The extra miles only partially balance the additional cost. In terms of performance I can't feel a difference. I think it's largely in people's heads/emporers new clothes syndrome when they say it makes an appreciable performance difference (on the road, on an SV).

As an aside, anyone else noticed how the price of high octane seems to of increased proportionally with fuel rises (rather than decreased as it should if the cost was fixed)? I was under the impression high octane was just better refined, rather than requiring more petrol fuel to produce?

I usually get about 9-10% more mpg with both car and bike using Shell V-Power / Optimax. Bike feels slightly quicker too, but that might be psychological because obviously I remember which fuel I put in.
