GM-GMC: Gas Consumption, mileage figures, one ton trucks

Question
Dear Dean;
   I want to know the fuel consumption stat or amount of GMC Rally 94 STX 15 passenger van. What is it where in internet I find it?

                  Thanks

Answer
Porya - As far as I know, there are no stated mileage figures for a van like this, because anything over an 8500 # GVW is not tested for fuel economy by either the manufacturer, or the government.  Even on the new vehicle window sticker label, there are no fuel economy figures on either heavy duty 3/4 ton, or one ton trucks.

One thing is for certain, depending upon what motor is in this van, it probably won't be very good.  If you can find out, the 454 will be about 12-15 mpg, and the 350 should be around 14-18 mpg.  Because of the amount of the frontal area of a van, they usually do not get great mileage.

If I can be of further help, please feel free to drop me a line.

Automotively yours,

Dean
