Sainsburys supermarket petrol?

The only difference will be additives added to the fuel. There isn't much difference in all honesty- I use Shell regularly because it is cheapest and I get cashback and points.

I do see a slight difference in how long a tank lasts to be honest between different fuel suppliers, I get about the same milage from Shell and Morrisons but less using Tesco and Sainsburys. Weird!

I don't know about the petrol, but I do know that I get an average of 54mpg using branded diesel against 47mpg using supermarket fuel.
It is all down to the addatives they put in at the time they fill up the tanker.
With Sainsburys only being 0.1p/Ltr cheaper than Shell, it would be really stupid of me to fill-up at my local supermarket.

BGefore anyone tries to rubbish my post, I ran my car for 2 months on supermarket fuel, then 2 months on branded. I kept a log of how much I put in, the price per litre and the mileage. Thats how I know about the differance in mpg.
BP uktimate also does exactly what it says on the tin, fuel efficeincy increases by around 10%.

Certain ages of car and models using ultimate diesel or petrol makes a difference but for most people it makes no difference. Unfortunately from what I've watched and read you have to try it out yourself to see if it makes a difference for you.

In the main the fuel into the tanker comes from the same tanks. They then put in the additives from the branded tank, and it mixes in the tanker itself. Even supermarkets have their own mix of additives. Whether it's the same as someone else's depends on the contract. It's like the Kelloggs in the Sainsbury's box question.
If you have a fairly modern car, with a closed loop fuel injection system, it will monitor the burn of the fuel, and the performance, and adjust accordingly, so it might well increase economy.
At the other extreme, if you have a carburetor, or mechanical injection, it'll just dump in the same amount of fuel every time, you may percieve an increase in performance, and drive a little less hard, but increase in economy will probably be minimal.

It depends on where the Sainsburys supermarket is in relation to the oil refineries. If BP is the closest then they will supply the local supermarkets. Fuel is a heavy and expensive product to distribute.

For example, Esso only have one UK refinery in Fawley near Southampton. They won't truck fuel up north to Esso forecourts in Scotland. Instead they will have Esso stations supplied by Ineos at Grangemouth (formerly BP). And BP will have reciprocal agreements with competitors to supply BP forecourts with fuel.

The base fuel meets certain requirements and the major operators inject a mix of detergents and other chemicals into the tanker for supply at branded stations. The major supermarkets get the standard stuff without additives.

This is the answer.

What happens with the Super Unleaded?
For instance i'm fairly sure Sainsbury's is 97 RON where as BP is 98 and i think Tesco's is 99

There are usually several tanks on your average tanker, mostly average grade fuel but with smaller quantities of the premimum grades, that gets offloaded at the different stations.

Yes
Sainsbury's is supplied by BP. The only thing that varies between fuels is the additives they put in them.
