supermarket petrol

[Roymondo]

They are not added by the driver at the filling station. They go in at the distribution terminal, with the mix being controlled by a swipe card system. This means that, although the base petrol is indeed the same stuff, only the BP garages get the BP additives, only Shell get Shell etc.

As for ethanol - some of the petrol sold on UK forecourts already includes 5% of the stuff, even though the label on the pump may make no mention of it. Next time you are at a filling station, wander over to the delivery ports (where the tankers discharge into the storage tanks) and have a look at the grade tags. If it says "UL95 BIO" on them, iy is "Bio Unleaded" and contains ethanol. I think this 5% may be going up to 10% soon (it may already have done so), putting us in line with the rest of Europe.

The shell station here has a sticker on the pump saying it has 5% Bio fuel where Morrisons has a sticker stating it has 7% so the content does change between suppliers. The potentially bad part about this is many car handbooks (mine included) state that no more than 5% can be used. I haven't looked at the bikes book yet to see if it says anything about it.
