Has anyone got any strong opinions on the merits or otherwise of using branded fuel, ie. Shell/Esso over supermarket fuel. Do you get more mpg using branded, is it better for your engine ? I tend to look for the cheapest option but is this a false economy ?

Have a look at  Esso card discussion in this forum and there are some comments about supermarket fuel which may help.

Recently there was some well funded and extensive scientific research carried out to answer this question.  Annoyingly I can't now find a link but the conclusion were:

  1. The base fuels are identical and come from the same places and processes.
  2. The performance provided was identical.
  3. The only difference was tiny amounts of additives in some branded fuels the presence of which, according to the trials, made no difference in any respect.

I always fill with supmarket fuel and both our cars seem to run OK on them. I believe even the supmarket fuels have some additives. Certainly there seems to be some difference between them.  Our X Trail starts a lot easier from cold, in sub zero conditions, when its tank is full of Sainsburys diesel rather than Tesco.

not scientific but supermarket  fuel does me, never had a problem in the current car, nearly 100k in 7 years.

I've had diesel vehicles for about thirty years,  Landrover, citroens, renault, skodas, VWs, and a Fiat MH.. Over that time 99% run on supermarket fuel or the cheapest I can find anywhere ...Never had a problem.

My son works for a National company that uses many vans which do a high mileage.  They have been issued instructions, following advice from van manufacturers, not to use supermarket diesel fuel based on several instances of engine and injector failures.

There are few supplying depots of fuel but apparently the supermarkets keep their prices low by reducing the additives.

I had to smile when I read the bumf on a certain make of premium fuel which basically said it was all down to "molecules" (aren't we all?wink) and they really couldn't say that the improvements they said would happen would happen to everyone.,  eg certain high performance cars might benefit but then again some might not.

As others have suggested elsewhere. You could also get more mileage by driving in a way that reduces fuel consumption. So cheap fuel + economical driving = more mileage. smile
