300 miles on a full tank of gas

Crash

My Trans Am got crummy economy until the motor was broken in. Then it got GREAT economy.

Most 6-speed V8 LS1 combos get about 32-36MPG on the highway.

Sorry if this sounds like a know-it-all....but The way that I have always measured MPG is easy......I fill up and force-fill.......the tank.....dont worry about doing this, I have been doing it for decades and never had a problem with any car. By force-filling I mean: After you think your tank is full, I shake the car and let the gas level go down. Any car will hold and extra 2 to 3 gallons..........it may take about 5 minutes to get all the air out of the tank. By doing this, you get an accurate level to refill the tank on the next fill.
Record the miles till the next fill.........and then you have an accurate level to measure from...........the next time you force-fill your are going to know that the level is the same as before.....as in FULL

Say you go 350 miles and then force-fill again.....it takes 13 gallons.....since you know the tank has been FULL to the same point...you know that you have used 13 gallons....and your MPG was 26.92 MPG

To me this is the most accurate way to get an MPG for a car........I guess I am Squirrly but I do this almost every tank....

eehhhh??? So once you fill it normally, then shake it, where does the gas you have already pumped go?

The gas that you have already pumped sucks in a lot of air and the gas that you have pumped, of course goes in your tank........

When you fill your tank....there is a lot of air that is trapped in your tank and it goes to the top of the gas tank...... this is what can cause condensation in cold weather.....and you dont have to shake the car.......lol.....but it does help to shake the car because it helps work the air out of your tank faster.........
