• Any - Energy Density/MPG of Road Fuels 31 Oct 2011 (Forum)
  I have seen 35% jet fuel in winter diesel blends and as jet fuel has less energy per litre than diesel, you get (slightly) lower mpg. Also you can see that (one of the many reasons) diesel cars go further on a litre is that there is more energy in a litre of diesel than a litre of gasoline (petrol).
• water in diesel fuel filter 29 Oct 2008 (Forum)
  Well, I've had my welcome to the diesel world! Just bought an old diesel Peugot 309 and driving along a few days ago the 'water in fuel filter' light went on. Have done a little research and it seems this is a common diesel problem. I have several questions but please let me know if they're not appropriate for posting on this site - Could this indicate something more serious than poor quality diesel fuel (last filled up with Sainsbury's diesel, I think)?

• Low Sulphur Diesel Fuel 6 Feb 2002 (Forum)
  Your recent articles suggest that this fuel lacks lubricity. I have a 1996 Mercedes E Class, 300 diesel, with 68,000 miles and which I hope to keep for a very long time. On one occasion you sugested using Shell Plura which may help the longivity of the fuel pump, but this fuel is not available in my area.

• any - the two fuels very close on price now 23 Jun 2019 (Forum)
  I wonder if Diesel is going to stay closely priced to petrol for the forseeable, and is this related to differing sales volumes as the demonising of Diesel gathers pace...if the trend continues will the govt see a handy excuse to raise the fuel tax of demon fuel.
