Dustydog & others,
How do I do it? well I don't really know, but maybe it's because I've worked with cars all my life & as with all pieces of machinary I treat them with an awfull lot of respect (even when racing them, cars that is... mainly because when I did race I couldn't afford a a tow vehicle so I had to drive my race car to the track, race it & then drive it home afterwards! so I couldn't afford to blow the engine or gearbox on the track!).
I'm also fortunate inso much as where I live I can be on the "open" road within half a mile so can drive the Sorrie at its most economical speeds within a very short period of time!
Making sure that the Sorrie is in Perfect running order also helps, it's also helpful that I drive as per "fuel economy runs" thats to say anticipation plays a huge benifit, as does not accererating or braking harshly! also I do not coast to save fuel, but rely on engine braking & the engine management system to save fuel consumption!
I also avoid conurbations at rush hours, constantly accerating & braking plays havoc with fuel economy! on the open road I engage the cruise control & it's very rare that I exceed 65 solo & 55 towing.
When I was young & stupid (as opposed to old & stupid now!) Speed & 0 to 60 (or even 100) was everything, now it's 0 to 60 eventually!.......hence "Old fart mode"!!!!!!!!!
Kevin,
As I drive on average 50K solo per year the difference between 41.5 mpg & 35 mpg at 100.9p per litre means
