Ok this is not tying to be a scientific study and i know prices vary up and down the country and motoway travel is different to everyday and diferent size engines etc But . . . If you put a tenners worth of fuel in your van, on average how many miles you getting ?
At curent prices, you'd be lucky to get 1.7 gallons out of a tenner. I'd probably manage to get about 50 miles or so.....
i'd maybe get 25 miles seriously. well i used £30 to do 65 miles if that cheers you up. in comparrison i put £30 in my bora when the light came on and i've hit 220 miles and it isn't back on yet....
What I don't understand, and I'm being serious here for a moment, not taking the peee, is that the engine in your bus represents near-as-dammit the pinnacle of VW's development of the flat 4 aircooled engine. It's a type 4, fuel injected engine. They probably went a bit further with the aircooled in the T25, but bearing in mind that this was nearing the end of over 30 years of development by VW of the aircooled flat 4, and an engine produced shortly after the '70s oil crisis, why is it so thirsty? It can't just be about the auto 'box.
it's probably got compression problems i'd guess, it's fairly gutless, i know the auto zaps power and it's heavy but i can't keep up with @moley76 in his 1600.....
I've never looked or bothered to work it out. If I got a return of 40 miles out of a tenner id be surprised. If your mpg worries you you're driving the wrong kind of vehicle. I guess these engines in smaller lighter vehicles aren't so bad, but let's face it they're pushing 1.5 tonne of steel, through an inefficient drive train, on a car with the aerodynamic efficiency of a 3 story house and a ground clearance of half a metre.
