Have used an Applegreen near work quite a bot too, and also the odd time in other locations and never had a problem...and its would usually be filling up by a 1/2 tank or more at a time. ..so not just a tenner in with other fuel.
Interesting mix of results. It's only in the last 2-3 months that I've noticed the pinking. Prior to that as I pass an Applegreen on the way to the office, I'd fuel up there and it was fine up to that point. Since noticing, I rotated and used Applegreen, Topaz, Texaco and Esso. Any time I went back to Applegreen it seemed to me more apparent.
I don't know exactly what the differences between each of the different fuels are, but I'm led to believe that it's exactly the same quality of fuel that all brands use and it's only their own 'additives' that make the difference.
Maybe in that sense, if the quality of fuel coming in is shit, they'd all have the same effect.
Also heard that the quality of petrol extracted from US shale oil is poorer, has a lower octane rating than the normal stuff and it's this grade that is dropping in price in the US more so that then the higher octane fuels. Seems to be affecting the higher end cars such as BMW's and Mercs so their owners are not experiencing the same 'savings' with price drops as the rest of the motoring plebs over there. :-)
Might try and get the M converted to Kerosene and 'stretch' the engine life just in case it is stretching causing the problem :-)
Im using applegreen in enfield for last few years and have never had any problems with any fuel related issues with any of my cars. 1.41 a litre there at the moment aswell which is very cheap.
My father worked for a company and they had a credit card to pay for diesel for there vans they used to use a texaco garage down the country and some of the trucks started having problems. Then one brand new truck only 6 months old went into the mechanic broken down and turned out they had to replace fuel pumps etc destroyed the fuel system in the truck.
Yet i know someone who uses a different texaco all the time for vans and performance cars and never an issue.. so i suppose the moral of the story is it depends how honest the owner is they either use decent fuel or buy in cheap washed fuel!! So if there fuel is delivered at 3 in the morn by a truck with no logo on the side beware [emoji2]
I only ever use Esso and try to stick to the same garages too.
What do you mean by "pinking"?Quote:
