.i usualy use ultimate but due to my car chewing throught the gas at a fast rate (320km per full 75l tank) due to it needing a tune, i have chosen to use what ever i can put in it that makes it go so that would be 91 octain shitty fuel that still gets me 320km per tank
I seem to be averaging ~7km per litre with Optimax which to me seems a bit on the high side. Not sure if running in a rebuilt engine has any baring on this figure but I couldn't recall it being as low before - maybe I'm just noticing it more with the high fuel costs at present.
