• Renault Clio - Techron D Concentrated Diesel Fuel System Cleaner 28 Oct 2024 (Forum)
  Last year i was getting 58mpg on my clio but the MPG dropped massively to 50mpg and even after a minor service in January , The MPG  didn't improve, So i booked the car into ATS for a Major service last month which included adding Techron D Concentrated Diesel Fuel System Cleaner which i would imagine into the fuel tank. After a few days and a run on the motorway, I am now getting the 58 MPG so i would imagine that the Cheap fuel that i buy from Esso isn't all that clean. " I have a Card for Esso" ATS is selling Techron D Concentrated Diesel Fuel System Cleaner at £32 a shot with a ebay seller selling at £15 a shot, I just wonder if how this competes against Red X and other engine cleaners, Its certainly cleaned out my engine and it maybe worth buying a couple of bottles  I may give the ESSO synergy supreme a try the next time i fill up.

• Vauxhall Corsa B (1993 - 2000) - 1993 1.5d Bleeding Diesel fuel filter 27 Jan 2008 (Forum)
  My hubby has a 1.5D Corsa, on which he changed the fuel filter yesterday. According to the manual, there is a bleed screw on the top of the filter housing, which you bleed until it flows with diesel, to ensure no air in the system. He tried this, even taking the screw right out instead of the 2 turns the manual recommends, and no fuel appears.

• all - Synthetic fuels 31 Mar 2023 (Forum)
  Germany is asking the EU to urgently review their ban on petrol and diesel engines and  to consider running these cars on E-fuels.  The engines would still emit carbon at the exhaust but a carbon offset at production of the new fuel would offset this.  A device fitted to the engines would not allow the cars to run on petrol or diesel.
