Supermarket fuel v the rest

All would say is that Sainsbury's diesel gives me the same mpg as shell but 4p a litre cheaper

But I won't go back to asda again - got caught out and had to put a tank in at asda and ended up 4mpg less on that tankfull
This has been in the last couple of months.

If you are getting the same MPG on every tank then you either don't do much driving or you can't measure correctly.

Anyway to MPG on different types. Premium will give better MPG in most cases. However even taking that into account it still costs more.

Me, I'm paying around 7p more per litre for BP (non premium) as it's the only garage around here. Yes it's a very expensive garage. I guess they know they have the market. Plus it now has a little M&S for nice stuff! 7p more a litre is hardly worth bothering about though. I'll fill up elsewhere if I can but going somewhere special then the journey would cost more than the savings.

A bit like whisky then - all the same.

No. Not really.

With fuel is using the same base product, the only difference is the detergents and cleaning agents added before distribution. Unless of course, thats how you think whisky is made?

I can tell the difference between a malt from a blended whisky however i'm fairly sure my car cant tell the difference between them and nor can it tell the difference between BP diesel and ASDA diesel. Likewise i cant tell if my car happens to be running on ASDA diesel or BP diesel.

Of interest whhen i was doing 30K miles a year, i did brim to brim calcs on every tank of diesel and from which supplier i bought it from. The best range over the course of a tank came from a supermarket fuel. Premium brand fuel often only produced average results.

Whatever the accuracy of the whisky analogy, when it comes to manufacturing methods, I'm really not sure your car is particularly bothered about what the fuel tastes like.

Here's my 2p worth on fuel types and a high performance V6 3.0d engine.


I feel my car runs smoother on branded fuel. I won't use Sainsburys or Tesco's but will use Asda or Morrisons. Fuel economy varies depending on weather and state of the DPF. If it does a DPF regen then the fuel economy can be 6-10 mpg better.


For preference I use Shell v-power diesel. Mainly because I started getting DPF full warnings. But since switching to mainly v-power I haven't had any. I know driving pattern has a lot of bearing and I used to do a lot of motorway work but that has changed now after I completed a project in June so I am more wary of what fuel I use.


But as everyone says each has their own view. My wife only uses Morrisons in her hybrid and has never had an issue.

I'd love to hear the logic behind that...

Ok


I had a Peugeot 406 2.0 td and I noticed if I used Tesco or Sainsbury it ran rather rougher than using other fuels. The performance wasn't as good, and acceleration was poorer. The tickover was more lumpy. The engine seemed more 'sparkly' on other brands. I used to use Asda as I had their credit card just for discount on the fuel but noted sometimes the car ran differently which may have been down to differing quality of fuel from Asda?


So since then I haven't used them, the fact there is no Sainsbury's Or Tesco fuel point nearby is another reason.


But as I said my current car can have DPF issues so using a premium fuel can't harm it and seems to help particularly as my driving pattern has changed now. I'm not doing west mids to Chelmsford as a weekly commute!

I have driven diesels for 17 years and yes, there are differences in MPG between supermarket and branded fuels.

It does, however, depend on the engine. My 1999 Octavia with the 1.9TD engine returned the same MPG regardless. Whereas my 1997 Astra 1.6TD suffered a prove able 12% drop in MPG using supermarket diesel.

Same with my 1.6Hdi Berlingo. It all depends on how sensitive the fuel sensors are.

My mate had a Picasso with the same engine as my Berlingo and it had always been run on supermarket diesel. It ran sluggish as hell. He switched to branded diesel and over time, the additives cleaned the engine and it ran way smoother. In fact, he no longer needed to drop to 3rd gear to get up the hill into town.

12% increase in consumption?
One extra litre for every eight used?

Don't be ridiculous.

Just my 2 pennyworth. My Picanto always runs on Sainsbury's petrol(Cheapest in town) and averages about 55 mpg. I did put in BP on the way to Heathrow once and got about 2mpg more for the extra 7p/l.

I used to put vegtable oil in one of them, trust me they would run fine on anything.
