Well the latest news is that I filled up the tank. So far I've got 490km on 4/9ths of a tank of fuel. Fuel tank is a digital gauge & I am fairly certain the last "tenth" is the reserve. Total fuel tank capacity is 90L. I'm getting 120km per tenth.
This is without the front & rear undertrays but the van is lowered now.
I'm not sure what the reserve is, but it looks like I'll be getting an estimated 7.5L/100km, in this configuration. Not bad for the most powerful version of the engine. I'm hoping to get down to 7L/100km and call it a day.
