5th gear did a test of optimax last night didnt they??

i didnt see it but heard it made a fair diffrence to a scoob i also heard u had to reset ecu to run it properly how do u do that on a vr??

I would assume you just disconnect the battery for half hour to reset the ecu?

in a vr, i think the only thing that would detect the optimax is maybe the o2 sensor...since optimax is more combustible, less fuel should be required for a cylinder burn, so the injectors are told to cycle less...i dont bother with optimax, i think tesco 98 ron is fine lol.

tesco's is 99 ron isn't it?

[Nerih 0]

it says 99 on the pump, but im sure its just as good as optimax

[Pittuf 0]

99 is better....I want the 100 stuff they have in europe

If Tesco has 99ron then that's higher than Optimax which I am certain is 98ron.

There are a couple of products about which raise the ron rating by a few points, basically octane boosters. I've used them on past cars and it seems to work but means you have to add it with every tank full which isn't cheap (

I've used that octane booster once...it did seem to make a small difference.
