Well I got into a convo with a mate about Optimax.. telling him it's not worth it etc... basing my argument on heresay.

Then after that I google'd it and read some reviews.. and I had to say that they were all leaning toward the positive side of it.

Then I read a forum thread somewhere about BP Ultima vs Shell Optimax... again, Optimax came out top because it's a higher RON... but interesting thing was, it was posted by a VR6 driver, which got me thinking...

does anyone on here use it and do you really notice the difference? Basically I'm starting to feel inclined to start using it too, lol... there's a Shell garage in Denbigh that I pass all the time.. so I could fill up there instead of Asda next door

Methinks also, that if I do switch fuels.. I'm gonna have to run as low as possible (not too low, don't want the gunk from the bottom of the tank) and then unplug the battery to reset my ECU to get even more effect from the fuel change... if I'm not mistaken... ?

apparantly mk4 nd m5 gtis and things in tht poewer ranhge mst use optimax as its wat the engines desinged to run on higher ron fuel

i use optimax wen i gt spare cash

i got a 1.3 carb and if i use normal fuel it doesnt run properly - ask sleeper he had to bump start it with me

it`s unlikely its a coincidence to because it happent literally every time

Yeah, It does make some good noises though :p

fully fueld up with 99 ron today... dunno if it's just psychological, but I thought I could already notice the difference, rofl.


Anyways.. yesh.. gonna try just keeping that in the belly of the best from now on

I have to use optimax, on my daily mk1 gti. the old k-jet needs 98 ron fuel. have tried cheapo supermarket fuel and get the occasional pinking from engine under heavy load. Not good.

Same. I set-up my timing originally forgetting that it had optimax in, if i use anything else it runs like shit.

It's v power now it's all I use in the loop

v-power for me an ye u can notice the diff espcially in the vr

ive got no choice and have to use it as my ecu is mapped to it,its dear tho and i put 60 quid in my tank yesterday which didnt even fill it and the price keeps rising,good job its a weekend toy.

I always use V-Power too (bloody expensive now though!!), can't comment if it makes a difference though as I've never put anything else in the car.
