Supermarket Diesel And Jags
Discussion
Picking up an XF on Wednesday. 3.0 V6 2012
Seems to be some opinions on whether supermarket fuel causes problems or not, so what the consensus ?
I've run a 2.2 Mazda for 45000 miles without any problems,
Are Jags a bit more sensative or is it just best to use v-max or similar.
Opinions appreciated , don't want to ruin it for a few pence per litre,if that's what it is, I've never looked.
Thanks Andy

Some swear by supermarket fuels, others avoid them like he plague. Jags are not sensitive, but there have been cases where supermarket fuel has caused issues, but not only to Jags.
In my experience, the money saved buying the supermarket fuel is cancelled out by the reduction in mpg I get. So given the extras you get in branded fuel, that's what I use. I don't use Vmax type fuels, just the regular.

Sometimes supermarkets use dubious sources for their fuel. That's my understanding. Sometimes they're on par, sometimes you get a crappy batch and the engine just sounds like it's working harder than usual.
This is a general comment, not related to Jags specifically.
Given that Tescos does't have any drilling rigs in the North Sea, I imagine that they get the fuel from the same source as BP/Shell etc. This is a general comment, not related to Jags specifically.
What is different is the "recipe" of additives to the base fuel. This is what makes the "Brand", and where the supermarkets scimp, thus reducing rhe cost to us. The additives are the octane/setane enhancers (which the supermarkets will use), as well as detergents to help keep the fuel system clean (not used as much by the supermarkets).

I think you'd be OK with Sainsbury's diesel but you'd be chancing your arm putting Morrison's diesel in a Jag.
I had to use Morrison's when I was caught short. The only issue I saw was the reduced range I got from that tank - which offset the cheaper price. If I kept on using supermarket fuel, then there's a chance on higher mileages that problems may develop. For these reasons. I don't use supermarket fuel unless I really really have to.fatboy b said:

BP/Shell have total control from rig to pump in contrast. Who knows where Supermarkets buy their petrol and diesel...

I run my 3.0 XF S on a combination of supermarket fuel and V-Power.
I usually try and do every fourth tank with V-Power otherwise it's Tesco's regular stuff.
I get a slightly better range with V-Power but not enough to worry about going out of my way to get some.
I find very little difference in performance between the different types if I'm honest, maybe it pulls a little better with V-Power but maybe it's just in my head.
Regardless of what fuel I've used it's never been anything but quiet, fast and refined.

I think they source the complete product from third parties - some of which add good additives and others that don't. I recall dodgy batches being sourced in EasternEurope not long ago at Morrison's

As has been said - there are only a limited number of refineries and import terminals in the UKBP/Shell have total control from rig to pump in contrast. Who knows where Supermarkets buy their petrol and diesel...
However, my understanding is that Asda and Morrisons buy on the 'spot market', so there's little consistency between one tanker and the next - Applegreen and Harvest also do this.
One thing that does differ is the additives - big oil companies spend tens, if not hundreds on millions on additive formulations, whereas supermarkets mostly take an off the shelf solution.
There's one supermarket in particular which appears to have issues with their additives. Every little doesn't always help.

There is no evidence that any one fuel is better or worse than any other over a range of applications. You cannot do a test by filling up with a supermarket fuel and then next tank with a premium fuel and trying to compare. To be able to do that you would have to be able to clean out the whole fuel system and ensure the same temperatures and atmospheric conditions etc. That is just not realistic and any "difference" you feel is all down to the fact that you are looking for it and know that it should be there. If you really want to try a test then ask someone else to fill your car and then try and guess what fuel they have given you.

Very witty, I meant what terminals and loading facilities do they use that are independent of the major companies who, I believe, provide all the fuel supplied in this country. For example at an Esso refinery fuel is collected by BP, Shell, the supermarkets etc if that is their nearest depot.. I would like to understand how they get fuel to all their nationwide outlets from say Southampton. Do they really truck it all the way to Scotland?

They don't - but there are many, many more collection terminals around the UK than most people realise. Plus there's a lot of trading goes on across terminals.Tim
For much of the South Midlands - South West, for example, if you're buying on the spot market, you can pull from terminals in the midlands, Wales or Bristol area.
