I have always used optimax but am considering trying ultimax for a few months , would be interested to see what people mosty use ?

 

ultimax !!! I meant ultimate

 

Not bothered which really, if I'm on 230 miles and I'm at a BP - Ultimate, or at a Shell - Optimax, or an Esso Superunleaded.

As long as it's not less than 97RON who cares

I've chosen any unleaded, by that I mean any high octane unleaded

 

I use Ultimate as the BP garage is closer than the nearest Shell garage.

If they were the same distance I would probably fill up at the one I was passing.

 

My work colleagues laughed at me, when i refused to fill up with Sainsbury's Petrol

 

Whereas we applaud u Ian

I use Ultimate a lot as I like the feel, but in summer I do ejoy the harsher, stronger Optimax feel

 

i dont notice a different between the 2, nor even Esso 97, Texaco SUL, Q8 SUL tbh

describe the difference, and how it works

 

Just spotted this on one of the other forums I read. Which is quite interesting...

[QUOTE]OK, so don't ask why, but I have a copy of a recent BSi certificate of laboratory tested octane values for some samples of petrol. I also know which samples were which, so I can match up the source with the results

 

Optimax because its several pence cheaper than Ultimate.

 

I've tried the BP......smoother than Optimax but the VTEC kick is softened

I use Q8 SUL if I am feeling flush as this in my experience provides the best performance but it's nearly 90p a litre

I use Optimax because the filling station is on my way home from work.....it's got wide bays too so no worries about numpties dinging the door
