Being ripped off for fuel

[IanF]

Probably to do with supermarket tie-ins.. there’s a Shell and BP near me, and I don’t know if it’s a real effect but I’m sure the M3 feels more powerful on Shell super vs BP’s. Prefer the M&S snack options to Waitrose though!

My E46 M3 ran noticeably worse on supermarket super, so i only ever used Shell or BP. never noticed any difference on any other car though.

The M3 does have a use Shell Super plastic moulding on the inside of the fuel filler flap. It may be marketing having a placebo effect on me or the engine may be tuned for their additives

All my ones which need super have been absolutely fine on Tesco 99. No noticeable difference on shell. Everything I’ve tried no ultimate in has hated it. Only ever used it in emergencies, would never use it by choice.

My stuff isn’t highly strung enough to matter much but ever since 10% ethanol came in I’ve stuck with super unless I know I’m going to go through the entire tank in a day or two. I use Gulf or Tesco.
Really notice how much quicker E10 degrades though.

I tend to use super about 50% of the time in the MX5. It doesn't need it but I do leave it without being used for a week or two sometimes, or longer over winter, so it's just because of its lower ethanol content. And I only use super in the garden machinery because some of it sits in the cans for ages, so I just fill it all up at once.

Diesel for the Audi I just buy the cheapest I can easily pass on my commute, using Petrolprices.com to find it. Tends not to be in Stourbridge despite the fact there are three petrol stations within a couple of hundred yards in Oldswinford; you'd expect more price competition but they're generally some of the priciest around.

I don’t use BP Ultimate if I can avoid it - doesn’t feel like good value at only 97ron when it’s no cheaper than other Supers.

Evora invariably gets fed Shell or Esso.

using Petrolprices.com

Thanks for mentioning that, I'd never used it, really useful as my local Shell is a solid 10p/litre more expensive than some others.

I never noticed any improvement between supermarket regular and premium super in the e46 330i, XJ6, 9-3 Aero, or 9-5 Aero. The Alfa 166 was a fussy bitch, though.

the 535d would probably run on wino piss just fine.

[Gavster]

I like using VPower Diesel, not because of any evidence-based benefits, but simply for quasi-supersititious reasons because it feels like I'm doing something nice for the car
