Fuel type and brand used?

You really should not put a lower octane fuel in a car than it was designed for, ie dont run a 6R Gti on 95, they take 98. The engine will have to detune itself to run it without knocking, and it may well still knock, which is not good for it at all.

But also, if the car isnt tuned and doesnt need anything more than 95 (ie 6C Gti) then you should run 95, anything more is a waste of money it seems from everything Ive read recently.

Ok, yes, I've had cars with learning ECUs that would retune on the fly, but that was usually down with bad fuel and then back up with the higher octane they actually wanted. So the gain experienced was the fact the car was really tuned for 98...

There is a lot of BS talked about fuel, and I know people who still fill their cars with a tank 98 on long journeys, convinced it gives them more kms from the tank than the old 91ish stuff their car needs.

At the end of the day you should just give it what it says it drinks, its like buying that mate of yours who drinks only VB a bottle of Squires. It will cost you more and you wont get any thanks for it...

I am a new Golf owner (MY10 118TSI) and I only use V-Power,
I have only used it in all my cars, (Previously Holden)
Is there any benefit to running Nulon Injector cleaner as well or just a waste of money.
Cheers

I only use BP Ultimate or Caltex Vortex 98.

There's pages upon pages of info and opinion on this kind of thing, but I assume it's all much of a muchness for any given octane grade.

The only reason I go BP and Caltex is cause they're closest to home.
