Need to know gear ratio to even make a guess. Does your odometer work? Fill tank, write down mileage. Drive. Fill tank again. Write down mileage again. Also write down how much fuel you added to fill it again. Subtract first mileage you wrote down from second mileage number. This is the miles traveled. Divide that by the amount of fuel needed to fill the tank the second time. This will tell you how many miles your truck travels per gallon without guesswork.

10-12 mpg.

But you have a Blazer!

You asked the SAME question back in the end of July. There are so many variables we would only be guessing. CSFJ and MikeB have both now given you the formula to figure it out. Please report back when you figure it out.

Lol damn, he hasn't figured it out since July?

Lol seriously?
