• Peugeot 306 (1993 - 2001) - 01 2.0 HDI Fuel pump/ immobiliser starting fault 7 Dec 2009 (Forum)
  This is happening every so often but only ever since my car got broken into, so 2 weeks later "today" the car was turning over fine but just wouldnt start so called RAC out to find the fault he ended up saying the fuel pump had gone and it needs replacing. BUT I have been wondering if the fuel pump has a feed from the immobiliser system hence cutting the fuel pump off? .********* If so then the fuel pump may not be nackered I may just have to take the drivers door card off and check the connections etc etc.
• Fuel efficiency priorities 20 Jun 2008 (Forum)
  An interesting article on the new scientist website today. They have some researchers arguing that presenting fuel efficiency in miles per gallon confounds decisions on how to improve overall fuel consumption. Their argument is very simple. An increase of 3 miles per gallon on a vehicle sounds insignificant, and on an already fairly fuel-efficient car it would be.

• Peugeot 307 HDI 2.0L 2002 - Engine won't start 7 Jul 2014 (Forum)
  I took the head off to check that the valve was still straight, which it was, and fitted a new head gasket and timing belt, along with a second hand fuel pump. The engine won't start. I've primed the fuel system and cranked the engine with the unions slack at the fuel injectors and there is fuel at each injector although there is some air in the fuel supply line to the pump which I can't get rid of.

• how to put up fuel duty AND save money 19 Aug 2009 (Forum)
  anual fuel bill of roughly 1800 quid road tax is roughly 200 quid for a family car like mine. 200 quid divided by 12,000 miles equals 1.6p per mile / 50p per gallon if they put 11p on fuel duty and scrapped road tax i would be about the same BUT the business high mile-ers who use lots more fuel pay more but can claim it back.

• MY17 Focus RS and premium fuel? 12 Aug 2017 (Forum)
  I am picking up a new Mk3 Focus RS tomorrow, and have been having an ongoing discussion, both on and offline, about the best fuel to use in it. Is standard 95Ron fuel suitable for the RS ( will it allow the car to perform at it's best ), or should I use something like Shell -V-power or similiar?
• Supermarket Fuels 21 Jan 2015 (Forum)
  Cue debate...thoughts? Which to avoid. Sainsbury's are currently offering the cheapest fuel however, would it pay to pay the extra and fill up at the likes of Shell / BP? Also, is it true Tesco use Esso fuels - and is it any good? I use diesel in my SD, I ask because I live near a Tesco garage and don't often pass Shell / BP.

• Fuel consumption at tickover 17 Jan 2006 (Forum)
  This morning, I was stuck in a 1.5 mile queue of *very* slow-moving traffic on the A33 heading towards M4 J11. With the fuel gauge in the red and the computer saying I had a range of 12 miles left in the tank, it got me wondering. How much fuel does a typical petrol engine consume (GPH) when just ticking over? Kevin...
