Super unleaded v98 whatever it's called

Chip fat red diesel and some M&Ms.. Itl run like a dream

 

i think unless youve got a motor specifically designed for super (ie Mitsi Evo etc) its pretty much a waste of time.

the experts say that it also takes more than a full tank of fuel for the ECU to sort itself out. Mixed reg and super defeats the purpose.

The only time ive noticed a difference is when driving my old Subaru Chavwagon. It specified Super, but once or twice i was forced to fill with regular and it ran like a pig..JDM cars will destroy their engines on regular.

 

if one sniffs the fumes, will it retard the rider?

 

only if its normally aspirated and fitted with a dummy blow off valve

 

You're right, a smouldering fag a mile away would cause an explosion.
