    Would have been nice if they tested some more interesting cars.. Even the Golf GTI is a perfectly mainstream car with a sports slant.

    I agree, that said What Car? have gone to the dogs IMO, its like a guide to cars for socialistic greenies rather than a magazine for people who actually like cars.

    Its sister Magazine Autocar is far superior, at least it is still what could be called a car mag anyway.

    The Golf has direct injection, and direct injection cars need 98 RON anyway(apart from the Volvo S40 with the Mitsubishi engine which Volvo say can use 95 RON perfectly well).

    Nevertheless the tests show an improvement in the performance and economy of the Golf so small that it is as near as makes no difference.

    Yep, sounds like you heard it before, but Im looking at a copy of Audi Driver and they have an article on the TFSI engine. Its mainly about the issues with the new type fuel regulator (a fully electronic, ECU driven FPR) in them which is experiencing some failures in the field when under high boost and high fuel pressure (1449PSI!).

    There seems to be a general issue with these FPRs and their measurement of data, but the note at the bottom states:

    "One final important point with any FSI engine: only ever use fuel of 97 RON or above. The system cannot run on lesser quality fuel and the combination of high compression and poor fuel combustability is not good".


    Does VAG really officially state T/FSI engines cannot run on 95? Sensible as it maybe, seems like a bit of a limitation.

    There is also 91 RON, which is not available in these Isles. It is more common in Eastern Europe. AFAIK It is not recommended because it is AFAIK not refined to the same degree that 95 and 98 RON are. Engines will accept using it, but it is best to use it as little as possible, especially with direct injection engines and high performance engines.
    Can most cars run on 91 RON normally? The manual for my Fiesta says you have to take out a certain fuse for it to run properly. From what I've seen it seems to be the "regular" unleaded available in a lot of countries (e.g. Australia), with 95 being the "premium". And according to Wikipedia, in Russia it goes down to 80 RON! So in all fairness we're not that bad off :)
