I am trying to work out why im getting such bad fuel economy in my gu8. Its getting between 24 - 26L/100km (average 450km from both main and sub tank). from what I can see most people seem to be getting between 12 - 16L/100km. It doesn't seem to change that much between towing or not towing. I would like to know if anyone else is getting such bad economy? It has the usual mods bulbar, 33"s etc..
I have checked filters etc. and all are good. so where should I go from there to sort this out? or have I just got one that chews the fuel
