LRP to be phased out. 3 Dec 2003 (Forum)
Lead Replacement Petrol to be phased out. http://www.theaa.com/allaboutcars/fuel/LRP.html "LRP now (mid 2002) accounts for only 2.7% of total fuel sales, and forecourt managers will increasingly be tempted to switch pumps to more profitable products. Trends indicate that you won't be able to find LRP from the end of 2003 except at a few specialist outlets hoping to keep something no-one else has." -

Golf 1.4E develops quirks 3 May 2002 (Forum)
Went to fill it up tonight and pressed the button beside the handbrake to open fuel filler cap and nothing happens. I can't get it open! Then driving home at a steady 56 in order to conserve fuel I noticed the gauges dip (rev counter and speedo) momentarily. (I had not changed gear or speed). -
Low Sulphur Petrol - Poor economy 5 Jun 2001 (Forum)
I've noticed that my fuel economy has dropped by ~2-3mpg, and performance seems to have drooped off, since the forced change to Low Sulphur fuel. Is this normal or should I be looking elsewhere? Exactly the same occured with my previous Diesel car when City Diesel became available. -

Ford Mondeo III (2000 - 2007) - 2.0 TDCi - Fuel System and Brake Light Despair! 16 Nov 2007 (Forum)
Had the vehicle checked out under warranty - 3 injectors replaced. Collected the vehicle September 2006 and was returned immediately for the same problem. 2 more fuel injectors replaced. I was told that the reason was "dirty fuel". In November back again all fuel injectors replaced and the injection pump. Again I was accused of using dirty fuel. Dec 2006 guess what back again more injectors replaced. -

KIA Rio Grades 1, 2 and 3 - Impact of tyre width/size/profile on fuel economy? 8 Jan 2014 (Forum)
Can anyone explain why the impact of tyre choice can have such diverse impacts on fuel economy? I have attempted to extract two tables from the KIA published data for the RIO - summarised below - they appear to show that KIA is 'admitting to' a fuel economy penalty going from standard 185/65 R15 tyres to a lower profile and wider 195/55 R16 tyre for three of the four engine choices but that unexpectedly on the 1.4 CRDI Manual ISG, going from the 195/55 R16 tyre on the Grade 2 Rio to a 205/45 R17 tyre on the Grade 3 RIO actually improves fuel economy? -

Yet ethanol is also a powerful solvent that, without a suitable additive, attacks many fuel system components including zinc and galvanised materials, brass, copper, aluminium, seals and hoses, cork, polyurethane and epoxy resins.
