Shell Optimax - is this statement correct?
"I'm always a bit suspicious about Optimax, because it's specified against BS EN 228 (95 octane regular unleaded) instead of BS 7800 (97 octane super unleaded). This suggests to me that it's bog-standard 95 octane with a cocktail of octane boosters and detergents added. No problem if you buy it from an outlet with a high turnover, so it's reasonably fresh, but I'd be a bit wary of getting it from somewhere out in the sticks - who knows what happens to the additives if the petrol is sitting in a storage tank for months on end?"

it goes off...
you are exactly correct!!!
95 ron has a better base fuel for adding octane to rather than 98 ron.
Leaded fuel is better still (4 star) but hard to get hold of and kills cats and o2 sensors.

More to the point, MON is a better rating to look at for forced induction vehicles, as it measures the fuels ability to resist knock at greater load. FWIW, I think the Tesco 99RON stuff has a higher MON rating than Optimax (but cannot remember the official optimax figures to be sure)
