Anyway, going to shut up now as this subject can tend to lead to some very heated debate when discussed on other forums. Hopefully we are a much more civilised bunch on here.

You do realise it's the like of Shell, BP etc that supply supermarkets?

Yes, I do know that all of the petrol here in Scotland comes from Grangemouth, and is exactly the same petrol wherever its destination may be. My neighbour's brother was a tanker driver out of there for years. It was he who first advised me that all the petrol is the same, its just the additives that are different. These are added later, but the refined petrol is a uniform supply.
Basically my point was more about avoiding, as best possible, any additives. Maybe a bit weird, but if we were all the same it would be a boring old world.

I agree, it's best to avoid additives.  I know the quantities are small but if you buy a litre of petrol you get a litre of petrol. If you buy a litre of petrol with additives you don't get a litre of petrol, you get slightly less than a litre of petrol plus some additives. The more additives they put it, the more expensive the fuel, so you're effectively paying more to get less petrol.

Yes there is. Always go to a busier petrol station, petrol has a limited lifespan and loses it's octane rating over time.

Your evidence on that?

Afaik most modern cars have an adaptive ecu which gets it's values from all the sensors in the car.

Afaik all modern cars have systems which measure ignition timing, airflow so they will adjust to changes in fueling, air temps and density etc....

Presumably the lifetime is such that this advice is not necessary with the exception of small rural petrol stations in the middle of nowhere?

I use best grade available.   And I will use an A brand, whenever I can. No reason not too

Ecu i understand constantly adjust itself for fuel quality. Not that's I think you will get more power, rather, you should get optimum performance to VW spec.

...and in a low powered car like the 75 pony Up!, you need very pony working for you
