I should mention that my tires are 265s or 32". Not sure how to factor that in to the mileage calculations though...

This rig had a tune up not too long ago; the plug leads look almost new and it runs like a top (except for the petrol usage) and I changed all the filters/fluids.

I need to find a way to read the codes (without paying $85 at Canadian Tire). Maybe the next step is to clean/test the EGR or just go for a really long highway drive...like to LA.
