• Farewell chug a chug Diesels - you served us well. 13 Aug 2009 (Forum)
  The finger of time draws a curtain over period where small economical diesels saved their owners a fortune in fuel bills - and... they could be used as desired without problems. Usually weighing in at around 1,000kg - family cars with decent sized boots and fuel tanks and with full size spare wheels.

• C-MAX Diesel Auto 26 Jul 2006 (Forum)
  Does anyone know if the C-MAX 1.6TDCi 109PS with the CVT auto is any good? If not, can anyone think of any other diesel automatics that offer good fuel consumption within the same sort of price range? Interior space is also a priority.
• Was diesel cheaper than petrol 28 Aug 2003 (Forum)
  Is it my imagination, but did diesel used to be cheaper than petrol in summer and slightly more expensive in winter when people bought heating oil? I was looking forward to cheaper fuel in summer. Oh well. On my 3rd Citroen. Saxo, Xsara, C5.

• Peugeot 405 Diesel (1988 - 1996) - Year unknown TD - Fuel starvation - won't idle 22 Oct 2009 (Forum)
  The probelm seems to be far worse when the engine is completely cold. When priming you can hear the fuel flowing into the filter chamber. The filter was changed three days ago, and has made no difference. It is running on veg oil/diesel, mixed, but this problem has only recently occurred, after several months of veg oil use.

  Has anyone else bought a new Ford Mondeo diesel 2.0DI (115bhp duratorq engine) and been disappointed with the fuel return when compared with the fuel returns quoted in various magazines and websites?

• Mazda 2 1.6d Sport - Diesel Engine Maintenance 1 Dec 2021 (Forum)
  Having bought a diesel car this week which is 9 years old and has about 66k mileage i was wondering what people's thoughts are on looking after the engine, is it worth adding fuel cleaners occasionally when i fill up? Is Shell Diesel really better quality and better for the engine than supermarket diesel?
• SEAT - Morrisons new bio-diesel 12 Jan 2009 (Forum)
  I was at a SEAT dealer the other day and there was a new notice saying if you use the newest type of Morrisons bio-diesel you will invalidate the warranty on your fuel system, including various bits of the engine. The notice said this new diesel contains 30% (I think that was the proportion) of bio diesel (mixed in with the regular stuff) which was not compatable with the engine.
• Turbo diesel or not 27 Oct 2008 (Forum)
  I'm looking for a s/h diesel, I see a lot of turbo versions and I'm giving them a miss as I have the idea that they are not as economical. Given the equivalent engine size and car is this correct? As far as I'm concerned the whole idea of owning a diesel is for economy bearing in mind that diesel fuel is about ten pence more per litre, a turbo might not be any cheaper to run than a petrol vehicle.
