well bought my tranny 100LWB sunday had my 1st long run in it today 350miles down to southend and back to notingham. she run good and got just over 1/4 tank of fuel left aswell. not bad i dont think. 2morrow shes going down to bristol and back to nottingham 360 mile round trip.
mate you need to fill it to the brim then run it for however many miles then fill it to the brim - note the litres and miles to get MPG theres a thread on here somewhere
im going for my record mpg this weekend billing and back one tank easy
