I left my wallet in London last week. It’s safe but I won’t see it again until Wednesday and the prospect of being without cash or a Visa card for five days  is something of a nail-biter. Not least, do I have enough fuel in the Shogun to see me through?

The SG4 model is claimed to average 33mpg but just like every other car sold in this country, it’s impossible to get within a gnat’s crochet of the official figures. I don’t entirely blame Mitsubishi for this – it’s just totally misleading for the car buying public when they look at the figures and calculate their own future fuel costs.

The manufacturers would argue that all cars are now tested on the same level playing field for fuel consumption, so it is the fairest method. I would would still say that there has to be a better way to give motorists an accurate figure!

So despite a light right foot since discovering the wallet missing, I’m only achieving only 27.4mpg. And I’d like to think that I can drive fairly economically when required after all these years of testing cars. We are being mislead but nobody seems to want to do anything about it…
