• Diesel Fuel Economy & Acetone 11 Jan 2007 (Forum)
  Hello everyone, I run a high mileage (>140k) VW Passat 110 TDi and have never tried using additive such as Millers etc. (See previous topics) In September Roly93 mentioned adding 1ml of Acetone for each litre of diesel in a previous discussion thread. Sounds like a good, cheap fuel-saving tip! Please let me know more re Acetone....(would the engine be at any risk?) (I must add that I acheive >53mpg on any trips over 10 miles [after which my old cruiser is well warmed up] and 49mpg around town on rarer short trips so I'm not overly worried about fuel economy!)
• Terrano diesel lumpy tickover 21 Mar 2005 (Forum)
  On a 1999 Terrano 2.7tdi automatic the tickover is erratic sometimes and at other times displays a "hysteresis" pattern (thrum thrum thrum like an old commercial diesel). however normal running is OK and fuel economy as normal. Car is regularly serviced so filters should not be clogged. Have tried Redex diesel in a tank of fuel without much success. Any ideas? Not too worried because I'm trading it in soon and the problem is probably not bad enough for dealer to notice.
• HELP!! No fuel to engine-MK3 Golf Diesel 8 Oct 2006 (Forum)
  The car did the same, twice. We got the AA to pick us up and take us home. Once home I changed the fuel filter (i had a spare) and it still wouldn't get started. I thought it could be a problem with the fuel sensor on the dash so went out and got 5 litre of diesel. Made no difference. I then took the fuel pip out from the fuel filter to see what was coming out when i started the engine....there was nothing.
• 2010 vauxhall zafira 1.9 CDTi diesel - ZAFIRA DIESEL 1.9 CDTi - FUEL ADDITIVE ? 25 Sep 2023 (Forum)
  I took it to the dealer but no error codes were found so they recommended I take the car for a monthly drive on the motorway for 20-30 minutes in 4th gear with revs between 3,000-4,000 rpm and that should fix the problem. So I am trying to do that. Is it also a good idea to use a diesel fuel additive to clean the Diesel Particle Filter (DPF)? I have never used an additive before and would like the opinions of others who have. nn Thanks in advance for any responses.
• Ford Focus 09 Tdci - Fuel leak (spraying diesel) 14 Feb 2015 (Forum)
  I noticed a slight smell of diesel a couple of days ago, around my car and I dismissed it as some spilt fuel from the petrol station. It's gradually got worse and is now coming through the vents and into the car. I had a look under the bonnet tonight after work tonight and although there was no obvious signs of a fuel leak on first inspection, after I'd started the engine and put my foot on the accelerator a big cloud of diesel proceeded to spray up and over the engine block.
• Diesel filter priming - Mk4 Golf. 7 Mar 2004 (Forum)
  Can anyone recommend how I should prime a new diesel filter for fittment to a MkIV Golf TDI engine. There is no manually operated pump to prime the fuel system - or if there is I cant locate it..... It also states in the handbook that if you run out of fuel, it may take the engine longer than normal to start - it specifies up to one minute - as the system must be freed of air.
• Avoiding using the wrong fuel 22 Nov 2006 (Forum)
  Despite colour codes and different size nozzles etc, it's pretty obvious that passive methods of avoiding using the wrong fuel on forecourts aren't working. What leads to the worse consequences - putting petrol in a diesel car, or diesel in a petrol car? I am looking for a used car - but there's no way of knowing about errors made in its refuelling history.

• BMW 3-Series E90 (2005 - ) - "Bad" Fuel? 1 Jul 2008 (Forum)
  I filled it with ostensibly the same Diesel Extra. Since then the engine has been running rough, performance has been down and the OBC indicated fuel consumption has dropped to 31mpg. Bad batch of fuel?

• Renault Kangoo Combi (1999 - 2004) - 1999 1.9 diesel - stop valve solenoid 13 Jul 2008 (Forum)
  RENAULT KANGOO 1.9 DIESEL CODED STOP SOLANOID hello, i have just fitted a diesel pump to my renault kangoo and it didnt pump any fuel through to the injectors , fuel got to the pump but no further . the kangoo is fitted with an imobiliser and i think this stops the fuel stop valve salanoid from oppening using a code. now could i have a new code added , or the old 1 changed , or do i have to take the old solanoid off and fit to the new pump?
• petrol in a diesel. please help! 14 Jul 2006 (Forum)
  The car is a T-reg (1999) diesel, would i cause more damage if i were to just fill the tank with diesel and just keep topping it up? or should i just bite the bullet and pay £80 to have the tank emptied at a mechanic?
• Re: Help - Wrong fuel!! 14 Dec 2005 (Forum)
  I put £4 worth of unleaded into my boyfriend's diesel Golf TDI S reg today. Petrol attendant told me it would 'probably' be ok to top it up with diesel and let it run for a few minutes to burn off. It ended up with £40 diesel to £4 petrol and has run fine for a 200 mile return trip.
• problems with fuel sender - Fiat Ducato 24 May 2006 (Forum)
  My theory is the tank was not changed which is causing problems with the fuel properties Diesel more dense than Petrol. This is only a guess. Has anyone got any ideas please? Thanks. Mike.

  Do the fuel companies still alter diesel at the refinery, according to season, to avoid the waxing that used to plague HGVs?

• Honest John’s Motoring Agony Column 24-06-2017 Part 2 26 Jun 2017 (Forum)
  Did he fuel it by using his own canister? Perhaps he was using red diesel or something like that - an extremely expensive error!
