• Diesel Payback Miles 5 Nov 2002 (Forum)
  Diesel cars are more economical then petrol but the cars themselves cost more as well as the fuel. Over what mileage therefore does a new diesel vehicle become a cost effective buy? As a further thought , why are diesel more expensive when the engines are, allegedly, less complicated?
• Running out of diesel 15 Sep 2002 (Forum)
  A question from someone new to diesel..... If a petrol car runs out of fuel I just stick some more in and go. I've heard that a diesel has to be put through a certain procedure; 're-priming' or something like that. Any advice please!
• Cost per litre? - Fuel Duty 15 Sep 2018 (Forum)
  From the HJ article.   "Aside from the fact that petrol and diesel in the UK are subject to some of the highest levels of taxation anywhere in Europe" Misleading or what? It isn't JUST the taxation that matters, it is also the fuel staion margins. See the price of a litre of unleaded in the rest of europe!
• Fuel (Lack of) economy - Winter's here! 2 Feb 2014 (Forum)
  Fuel light came on well before the normal figure of 400 miles...according to FuelLog, the Berlingo did 33.6 mpg to the last tank!  The last fill up on the 18th worked out at 38.4mpg, looks like the winter diesel switchover has occured.

• Common-rail diesels 9 Sep 2003 (Forum)
  Can we have a brief explanation of why the current generation of c-r diesels no longer need the 5-second warm-up of the previous generation? Is it just the high-pressure fuel, or is there more to it than that? (MM?)

• Volvo V50 Diesel - Wise buy? Volvo V50 1.6 Diesel (better than 2.0l?) 16 Aug 2012 (Forum)
  A few horror stories around the internet, which seem to centre on the 2.0litre diesel(poor fuel economy, engine probs) I wonder if the 1.6 diesel unit is a better, more reliable unit. It should also have better fuel economy. Monthly running costs are very important to me, I can't afford a car which is going to let me down.
• Diesel or petrol 29 Oct 2003 (Forum)
  Do diesels require services more often? Does the cost of maintenance outweigh any benefit in fuel consumption? Just trying to get some answers to common questions I guess. Thx in advance. S.

• Ford C-MAX TDCi - Cleaning up after diesel leak in engine 23 May 2011 (Forum)
  I'm very suspicious that the nut in question would suddenly be loose after a service, especially when they had trouble fitting the fuel filter. I've never had trouble with the fuel system before. Needless to say there's diesel all over the engine. What's the best way to get the engine cleaned? Is a steam clean recommended these days?
