OK i'm looking at buying a van real soon.
now i've just enquired with a bloke about his nice looking Mazda LWB E2500 diesel and he seams to recall it only got about 450 -470 kms out of a 62L tank which works out to be as bad as 13.8L/100kms.
Now this may have been with his tools in the van and he may have a lead foot but comparing on redbook the equivalent Hiace is 10.2L/100kms and VW transporter 9.1L/100kms.

am i being too picky about fuel efficiency??? I guess i'm used to driving a commodore taxi around, so this is about 2L/100kms worse than what i'm used to. which equates to about $5 / 100kms more than a commodore which can go fast and overtake stuff on country roads!

What does your van do???
