Polskamafia mjl my old buddy, I've come to the conclusion it must surely be an American thing.
The point I've tried to make repeatedly is, the mileage some owners in America claim to get is, basically, not matched anywhere else in the world that I can see except from, maybe, one guy in Estonia.
Some claims appear quite acceptable while others, when calculated (converted) in Imperial gallons, become nearly laughable.
Unless my mathematics is wrong (and I don't claim to be a mathematician), where fuel consumption is listed in m.p.g (U.S gallons), to calculate what fuel consumption the very same vehicle would get per Imperial gallon, the U.S mileage needs to be multiplied by a factor of 1.3
For example, where it is claimed a Volvo achieves 35 m.p.g (U.S gallon), then this is the same as saying that very same vehicle would achieve nearly 46 miles per Imperial gallon.
I've scanned through most of the non-U.S boards and I can't find any posts where a person claims their petrol engined Volvo 850 achieves this figure (i.e. 46 m/Imp gal). Maybe you can find some that will prove me wrong.
So I guess that beings me back to my original point - as I said - it must be an American sort of thing (i.e. the air, better road surfaces, better maintained vehicles, better quality vehicle polish, Volvo install a more economical engine in their U.S. vehicles, etc.) although common sense tells me this is complete BS.
P.S. I'm not really influenced by people who take photos of their instrument panel readout displaying very light fuel consumption as proof their vehicle actually achieves the indicated fuel consumption. Unfortunately, these readouts are easily obtained and, if a person wants to cheat to prove their point they only have to;
(1) reset the computer before coasting down a long gradient then;
(2) raise both engine revs and road speed to make it appear the vehicle has been travelling along at normal road speeds then;
(3) photograph the instrument panel when the average fuel consumption figure displays the desired fuel consumption figure.
There are only two types of car owners - those who own Volvos and those who wish they did.
