It coincided with a year long test I'd been running on petrol consumption. Apart from start ups I've only run out of LPG once in the year and only covered 12 miles before finding gas, which I thought was quite a good effort, but still managed to consume £220 of petrol over the year. Throw in the extra servicing and potential extra maintenance and I think its time to go back to a Diesel van.
Whilst I was saving a tenner a day in charges it was a no brainer but like most loop holes they're always closed in the end.
Forgot to add can't seem to better 16mpg on gas whether I'm driving like Miss Daisy or Lewis Hamilton, where as my mates new shape diesel Transit manages well over 30 mpg on diesel on similar journeys to mine.
