Lol, I worked in fuel terminals in the oil industry for years and the supermarket fuel comes from the same tanks as every other petrol station. There are not special fuel terminals to buy cheap rubbish diesel from. They only have one type of diesel in a fuel terminal and supermarket truck roll in with the BP and Texaco trucks.

Same raw product but more additives in the premium stuff is how I have previously understood it. It's made a hell of a difference to my car idling I know that much! |

According to Google and rac watch supermarket sell 44% of our fuel, so must be a lot of cars running on it. A bit like pattern parts for cars there seems to be a big market for them. |

Whilst BP ultimate petrol offers higher BHP /MPG because it has a higher octane rating than normal unleaded their Ultimate diesel can offer no such benefit. The only thing it can offer is some cleaning effect which may help if you intend to run your engine for a very long time. or if youve treated your diesel badly by nannying it and/or lots of short journeys. AFAIK there is no independent evidence confirming the long term benefits of these Ultimate fuels, nor is the research ever published, which is surprising as you would think that if it did make a difference BP or Shell would publish the independent data to convince us to buy it. To quote BP "bp Ultimate Unleaded has a higher octane (97 RON minimum) than the minimum 95 RON required by law for petrol in the UK. For petrol vehicles that have been designed to take advantage of a higher octane fuel those drivers could achieve some immediate fuel economy benefits although this will also be influenced by their driving style. bp Ultimate Unleaded also contains a friction modifier which improves the upper cylinder lubrication of the engine. This can contribute to improved engine efficiency and therefore improved fuel economy. For diesel vehicles the fuel economy benefit is primarily derived from the removal of dirt from fuel injectors; bp Ultimate Diesel cleans away the majority of dirt in diesel engines in just two tankfuls.* Actual fuel economy benefits achieved from using bp Ultimate may vary depending on vehicle type, condition, engine technology, driving style, road conditions and other factors such as length of journey, climate, tyre pressures and vehicle loading. *Benefits vary based on what and how you drive. ** For Ultimate Diesel based on engines tested in dirty vs cleaned condition and for Ultimate Unleaded vs RON95. Benefits vary based on what and how you drive." FWIW I chuck some 2stroke oil in with the cheapo diesel every now and then as its a superb upper cylinder cleaner. Jules |

Dont get me wrong, injector cleaners do work. I bought an Opel Manta GTE in 1986 with 110K miles. It regularly hiccupped upon accelerating from stationary. A can of Wynns Injector Cleaner at double strength cured the hiccupping once and for all. Jules |

But the biggest cost of car ownership is depreciation. Keeping an old car going is usually way cheaper than buying a newer one. Spending say £4k on a new part is far less than the depreciation of a new car. A bought a BMW 3 series in 2006 - the previous owner had lost £15K in the first year from new. I sold it 6 years later and lost £12k. Jules |

Thanks for the information Jules. I must admit I've got a bottle of Wynns Injector cleaner on my shopping list, as I suspected a partial clog there may be to blame for the symptoms. But I'm intrigued by the 2SO having seen many others recommending this. May I ask what type/ brand you put in? I see approx 300ml per tank seems to be the volume to add? |
