So, finally collected my van today after conversion completed. First time I’ve actually seen or driven it, so after reading this thread earlier this week, thought I’d see how it fared on mpg. It’s a new SWB 150 manual highline, with a full conversion running on standard 16inch factory claytons and tyres. Not sure on weight of conversion, but it’s got a pop top, solar, full EHU, water, seat/bed, full kitchen units, fridge, underslung gas tank and 80lt fuel tank. So not light.
Gave it a good 250 mile run home, having filled diesel to max and added some Millers ecomax. First half of journey was single track A roads, max 60mph (and a good few miles static or crawling through Dorset) second half was motorways, up to 75, not much use of aircon, and a good 45mins more or less crawling on the M25. So a mix of driving, and the overall return was 43.9 mpg. Id been expecting low to mid 30’s, so was very pleasantly surprised!
That was calculated on refill when home, so actual fuel used. Interestingly, it also aligned reasonably well with the van calculations, which put it at 42.9 mpg, so VW software is close but slightly under real world in my van.
If it stays around those numbers on mpg, I’ll be well pleased.
