For years I've usually gone for the cheapest fuel and is mostly that sold by the big supermarkets. I've heard that some supermarkets, Sainsburys in particular are known to water their fuel down. I don't know If this is true but I've seen plenty of exhausts blasting water out of the back box on setting off.
I do about 40k miles a year in my company diesel Ford transit custom and I am filling up more nowadays with more expensive branded fuels. I have noticed the engine is running quieter and I seem to be getting slightly more miles from a full tank. The difference of filling a full tank on supermarket/branded fuel Is about 6-8 quid.
What are you filling up with and why?
Her indoors got us 2 sirloins for £7 for valentines from Morrisons for valentines, spot on mate :)
Thought I'd jump in this thread and ask the question... Is there any difference or at least a noticeable difference in the quality of the "premium" fuels which are offered beside the "standard" fuels?
And if anyone here knows their Onions on this subject, which diesel fuel is best?
I tend to fill up at Tesco due to proximity to my home and price however I'd be willing to pay more for say BP/Shell if it was better.
Or Maybe a station which Sheikhy Boy supplies the most too??
Fuck all difference and don't let the moon landing deniers tell you any different.
supermarkets are allowed to use vegetable oil in diesel and methanol in petrol. it reduces the tax levy. Methanol is less powerful than petrol and also readily attracts water from the atmosphere which then causes rust problems to petrol tanks. Biodiesel has no downsides except it should be cheaper
Christ almighty lol.
that explains the "watering down" then.Catalytic converters turn unburned hydrocarbons into CO2 and water - that's what you see coming out of the exhaust.
You'll find butcher aren't much dearer than supermarkets, it s better quality too and probably local. Theres a reason any decent restaurant will always use a butcher for supplies.The average local butcher is no better than a supermarket. You end up paying more for the same stuff. Morrisons has an excellent butchers dept, better than all but the high end shops.
I work on a refinery, its all the same stuff leaving us and going to various forecourts doesn't matter if it's Tesco, Shell or Sainsburys. People are right in saying that you'll get a better spec in Cetane and Octane in the premium stuff but it's not going to have a massive effect and isn't worth the extra pence a litre in fuel economy in my opinion. You're better off driving more efficiently yourself.
It's been a few years since I've worked in the area in regards to biodiesel etc but there are downsides from what I gather it can have a corrosive effect on the fuel system and from what I last heard BMW and I think Audi were recommended it not be used in their vehicles.
seems like bluemoon has the fuel boffin i was after after all ; )I work on a refinery, its all the same stuff leaving us and going to various forecourts doesn't matter if it's Tesco, Shell or Sainsburys.
