Yesterday I was sat in a garage waiting for the MOT to be completed on my Volvo and a lady came in to discuss the problems she was having with her Volvo. The owner of the garage had just come back from test driving her car and was in a discussion with his mechanics as she arrived. He was saying to them the car was doing everything as it should and he could not find a fault and nothings showing up when its plugged in to the computer. One of the mechanics said that on his test a few days earlier it did what she was complaining of and was stuttering under load in second. The owner asked if they knew what petrol she used and the foreman said he had told her she put in good stuff.
It was at this point the owner came in and she was told that under this test test they did not reproduce the fault and again nothing was showing up. He then said where do you fill up, she replied Morrisons. He said that will be your problem, we get cars in here all the time with problems like this who fill up at a named branch. If we don't find a fault we advise changing to a branded petrol and after a few fill ups see what happens. The majority come back and say its cured, those that still persist we clean out the injectors etc and then that resolves it, so do the cheapest first. She was not to responsive to this so he went to the back of the room got a bottle off a shelf and said this is out of an Audi this week, its diesel from that branch having the same problem. The bottom of the bottle was full of black particle sediment which he shook up. We kept this because we were surprised how much there was in the tank. The car was too new for it to be from deteriorating hoses etc all was in good condition, but this was in the filters, pumps and injectors and from new he had only used Morrisons from that branch. She left convinced and then a conversation in the waiting area was had on where we all fill up and what with. 20% me included reported running problems with cars that ended when we stopped using Morrisons. My conclusions are that the evidence shows all companies buy the same basic fuels and then some add into that their own chemicals and additives to create better combustion, cleaner engines, hence those who recommend and prefer V Power etc. So all cars should run well and cleanly on any petrol/diesel, but some like my Volvo may smell of bad eggs when running supermarket fuel but that in fact is not harmful just embarrassing. Deposits that can block up injectors and cause poor running comes from dirty storage not the petrol tanks. It could well be that some retailers are better at looking after their storage tanks than others. |

You state that the car was a petrol car? What has that got to do with diesel? Ever since supermarkets have been selling diesel, I have used it. Never had any problems with it of any shape or form. There are to many people who have a conspiracy theory about supermkts fuel. Please pay attention to the following statement. Supermkt fuel is normally the standard set for the industry. Other fuels,have additives added by the driver of the tanker, as per instructions on the ‘fill’ docket. So all I can say is some people have a vivid imagination on how their car engine is performing. Stop imaging that you are being took for a ride by supermkts diesel.My son is a tanker driver for a well known company, and that is where this info comes from. It is not some sort of dream made facts, like fake news.By the way, I have been driving diesel cars since the 80s, and most definitely will not be moving back to petrol vehicles at any time in the future. Diesels are boring because they so rarely have any trouble.

Who remembers the dreaded ‘diesel bug’ ?
Personally, I think it makes more sense to either buy branded fuel or use something like Millers EcoMax additive that is kinder to the engine. I almost always use Shell not only as it’s closest but also because of the Shell Go app benefits. I do find the car runs better. My V6 cars have always performed better with VPower, though the livelier boost you get from the fuel means your economy drops quite a bit as you enjoy the drive |

The M47 is a pretty uncomplicated engine compared to modern diesel engines. (Thats why they are so reliable and are capable of doing mega miles!)Newer diesels have Coded injectors, electric EGR valves and DPF filters to say the least. I go to a lot of people (Diagnostic wise) who pootle around and very rarely give their car a decent run and use supermarket fuel only. Poor running car feels lumpy and the injector readings all over the place. A flush of Forte specialist injector cleaner and it usually sorts the poor running out.
If you are flying up and down the motorway I would say supermarket fuel is fine as the car is up to operating temperature and the engine is running freely and the exhaust gasses are being forced out as to say at a very high rate. I know many taxi driver (who do up to 60k a year and have very strict emission tests from the council and they almost run on pure injector cleaner when they go in for testing at the council) and they say Morrisons and Asda diesel is particularly smokier than other brands. Its all a matter of how you feel but I never get this problem when I visit people who use Shell or BP etc. Many on here use supermarket fuel and use Millers etc or Redex to keep their engine "clean" which is the same as using premium brands that already have the additive in. No problems when you use it fine why would you change? Its al down to individual experience. |

The Volvo at the MOT was a diesel and the comments made by the garage referred to that car so were pertinent and the evidence he gave and was showing related to contamination in the fuel causing the problem and not necessarily the fuel itself. I had had the same issue after using Morrisons diesel which ended when I stopped using their fuel so I can only come to conclusions based on my experiences. I use supermarket fuel from Sainsbury's but not the 95 Ron petrol because of the bad egg smell not its performance. I check my fuel usage and do find for whatever reasons that on every occasion a tank of petrol goes further from BP than Sainsburys as with diesel unless with Redex added. I have always accepted the fuels are all from the same plants but as was said on the TV just last week by the fuel manufacturing plants manager, additives are added by the brands after filling up their tankers. I do not accept that V Power etc. is the same as Morrisons or Sainsbury's etc because of this fact. And if my trousers are full then it smells of roses. |

This is basically it. Also, just because one person's car has been fine and the driver does not notice any difference between different fuels when driving the car under their conditions does not mean that there will be no discenible difference when the car is driven under a different set of conditions. Those who state with absolute certainty that different fuels do not make any difference and expres views such as "placebo effect" are actually highlighting a limitation in their understanding of the basics. Or, maybe, some of us just have better tuned sences? |
