Tuscan Fuel.

[RIP james]

Whot do use in the way of fuel in your Tuscans?

Shell V Power Me.

[Big GT]

I've found mine run the smoothest on normal premium JET.

I found Esso Supreme makes the engine run lumpy.

I always try a fill with 'branded' fuel. I have Esso and Shell local to me.

Having had a random "engine management/warning" light appear on the dash of the missus' Subaru, which cleared after filling at the local Esso station - and then querying this with the Subaru specialist we use - they just said...."yeah, supermarket petrol is the likely culprit."

Lesson learned for me!

Mine's done the best part of 20,000 miles on supermarket fuel with no issues, or at another point when I was commuting, about 18,000 miles on standard Shell, no perceivable difference in running between the two (When on Shell it was a full tank - £50 every 3 days!).

Tesco 99 for me -30000 miles done

I don’t notice a performance difference on 99 vs regular fuel but it definitely pops and bangs more with the higher octane stuff and that’s good enough for me

I always use shell v power, its nice and cheap. I do wonder if its a bit overkill though, but saying that i put esso super in once, strangely that put the EFI light on as soon as i pulled away.

Supermarket fuel should be avoided, they do not have the same additives as main branded fuels and will be harsher on the engine; it is cheaper for a reason.

Where possible I use VPower or similar, though not worried with the odd standard octane refuel.

Dickie, I'm of the opinion that supermarket fuel is bought on the European 'spot' market....for the lowest price on the day.
The major food retailers use fuel as a loss leader, just hoping to get customers on to the site.

My concern is with the quality control and storage of that fuel whilst being shipped.

I worked for an oil 'major', and remember one of the 'Board' coming to the refinery for a "face the Nation" session. His words were that they were considering pulling out of forecourt service all together because margins were so tight, and they couldn't compete with the supermarkets who used gas as a loss leader.

We did have a significant fuel contamination problem in Bournemouth/Poole a few years ago with a Tesco outlet. Several instances of lambda probes being burnt out/damaged.

This kind of thing is often trotted out when it comes to fuel. You present your statement as fact, do you have any evidence to support it?

It is an Urban Myth that supermarket fuel is of "less quality" They all buy from the same refineries. They only way you would notice a difference is if the fuel in the forecourt tank was open to the atmosphere. Petrol is hygroscopic (draws in moisture from the air) but due to the large turnaround the fuel won't sit for too long in the underground storage tanks. (Fuel does not go off unless exposed to air)
