A friend of mine told me that a honda dealer recommanded BP either.

Some said optimax is the best fuel in Australia.. and some said it is only good for turbo..

my gf's driving instructor said he used to read something was talking about shell and BP fuel. He said BP is always better, as it explode much better than shell..

Now i found everyone has different story

for me I could feel that shell optimax has better power, but i am not sure.. they both has 98 octane. Or maybe Shell has a cleaner petrol station, coles express discount that makes me feel better.

Any idea ???? just tell me how you feel or did anyone even put it on a dyno to test? but it must be done straight away.. like run with bp, clear the fuel tank put optimax ..

A mate of mine had fuel tested with his families formular holden race car and found that BP ultimate gave the best results closely followed by mobil 8000.
the results he got also stated that shell fuel was the dirtiest.

This was done a little over a year ago so the fuel mixture of shell may have changed since then. but i still go by it and only get mobil or bp.
