I asked a question that did not have enough details thus, I am re-asking the question and providing more details. How many miles can you drive on a full tank of gas in a 1999 Chevy Blazer

16.8 mpg average for 13 1999 Blazers on Fuelly. Your mileage may vary due to the way and where you drive. == http://www.fuelly.com/car/chevrolet/blazer

Multiply gas tank capacity by your average fuel consumption. If you're getting 16 mpg and your tank holds 18 gallons that's 288 miles. You have to do the math on your own. To find your average mpg fill your gas tank and reset your trip odometer. In a week fill your tank, how many ever gallons you add to full is a very close approximate to the amount your vehicle consumed. Your trip odometer will show how many miles you went with that fuel. Divide the top odometer reading by the amount of fuel you added. That's your average mpg. Call your local dealer with your vin ready and they should be able to tell you your tank size.

I'll be the smart butt today. You can go one mile, then your tank will not be full. Or you can go until it is empty. Fill it up, check the mileage, drive until you run out of gas and you have your answer. You can get more with highway mileage, not towing a boat or trailer. Better on flat land vs. mountain driving, and doing the speed limi9t and not keeping up with traffic. If you know your approximate mileage for the driving you will be doing, multiply it by the amount of gallons your tank. holds.

My 1986 full size Chevy gets 16 mpg. I drafted a semi from Indianapolis to northwest Indiana to visit my parents one weekend. Normal drive is 2 hours it took an extra half hour drafting the semi but I got 25 mpg....

How many miles do I have till my 99 Chevy Blazer runs out of fuel once gas light comes on
