cc123, i've seen this on a motors forum in a larger forum i visit daily and it has been posted numerous times and each time it has been totally dismissed, i'll see if i can dig out a thread and post the link here to tell you.

Only time i have noticed 'better fuel' having an effect was on a commando and that was most likely due to the fact the petrol we filled it up with before was a bit duff and that tank came from shell i think!

[cc123]

I think it started on a car forum somewhere but still, they charge more for it so you believe it's better.....


Piece of mind and all that?

If i remember it the only vehicles that really respond better to the high octane fuels are the Jap sports cars as they are designed for the higher octane fuels.

The letter/article/whatever is just some bit of propaganda from an employee of one of those big fuel companies.

It does come down to piece of mind i suppose yea, it's fun to believe it sometimes and it did make my dads commando run a bit better (it actually sat at idle!) but we both thing that is down to the fact the petrol we put in before was a bit off if you get me.

Have thought about trying optimax but never got round to it, I've never had any problems with my bike from cheap fuel.

[Fortuna]

Did you know even F1 cars use 95 pump unleaded
Have done for a couple of years. High performance doesn't always mean high octane.

Hi

Think the TT rules mean that bikes must use fuel available on the road. One team a few years back had their bike tuned to use a fairly special fuel which they brought with them. Their argument was that it was available. That it was only available at a single pump in the middle of Silverstone circuit was not relevant!

All the best

[mr.z]

Two words "paper filter" any fuel filth should be picked up, they only cost about £5 and take seconds to fit...

Tend to use the closest i can find, though reading that will steer me towards places other than asda and the like..

The only place i make a special effort to go to sometimes is a small "local" station, two pumps and thy do it by hand (not that i let them tho ) apparently the last fuel crisis they were only serveing customers who were there reguarly, which i though was ace, appart from 20p cheeper after a fillup (wooo indeed)...

I do use redex every so often though, the 300bhp extra BS i dont believe, but the difference is noticeable (only a bit) so i've no doubt its doing good to the carbs e.t.c. on old/simple engines its worth it, modern 4s doubtful it will make the slightest difference...

I normally always use Optimax or BP ultimate or as a last resort super unleaded in my bike. I think that with a 12.8:1 compression ratio the higher 97-98RON fuels must be better for it. I'll have a chat about fuels when i book my bike in for dynojetting when its back on the road. It was interesting to see in RIDE that Optimax etc, does actually give a tiny but measurable increase in power and throttle response over normal unleaded. Ive got a 4degree ignition advancer to go on my bike, so i guess its will be advantagous to use Optimax all the time when its set up properly.

Im my Car i use Optimax nearly always too, as its the idea of it keeping the engine clean that appeals to be. My Car does not have a knock sensor (Rover K-series engine) but when ive carried out some tuning modifications later this year, im going to have a auxillary ECU fitted, that can be programmed to take advantage of using a higher grade fuel, and on similar engines/Cars to mine it has shown a 2-3bhp gain on top of the normal gains made from chipping the engine, and i want to get every last bhp i can from tuning, so thats why i'll probably stick to Optimax or its equivalent.

F.Y.I. California's current higest octane rating for pump gas is 91.

Hi

[Tiger Lily]

Good old fashioned leaded 4 star, if I can find it, like rockin' horse poop now!
If not 4 star lead replacement, which is also getting harder to find.
Failing that, the green tap stuff with an additive.
Will now look out for the decent green stuff now, if I have to put that in!

[Knisis]

I don't think my poor Honda CLR125 12BHP would appreciate anything other than standard unleaded

[mrchips]

78p unleaded, none of the 86p super unleaded crap.

If it's green, it goes in. Simple.

I tend to avoid BP and Esso like the plague, they're really rather expensive compared to the supermarkets. If I was going to shop in a supermarket, it wouldn't be as a result of being lured in by the petrol either. Do they really think that selling cheap petrol is going to make people buy their groceries in preference to going to a different supermarket? Supermarkets are all the same, as is their fuel. Adequate.

Supermarket fuel prices means nothing to me. I could not be arsed wasting 15 mins of my life queueing, all in order to save 50p on a tank of petrol.
