300 miles on a full tank of gas

TerribleONE · 01-18-2009, 04:46 PM

i know on my G37... after about 5k miles the MPGs went up rapidly.. let it brake in.. it WILL make a difference on these motors.

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.........

Im getting around 240MPT and that is before I can go past 4k RPM. Someone help me.

trema · 02-17-2009, 04:40 PM

How much FPT (fun per tank) are you getting... that's the only appropriate question.

520 miles on one tank is my personal best ( shell gas ) . All interstate at 75 mph.

Blown32 · 09-01-2009, 10:41 AM

I like the car..I buy it! I don't ask or worry about fuel mileage!
I get a kick out of the people that ask "what kind of fuel mileage you get"!Nerds!
I have a family couple that when we go out as couples they break out there calculator to figure what each couple owes seperately instead of just dividing by number of couples?Tightwad whacks that won't even go for ice water.Mooch off everybody and when a barbecue they bring the cheapest six pack and drink everyone elses best beer!Needless to say they are not invited anymore to my house or at our events.
So I guess you know my opinion of the squeakers that are on here worrying about there fuel mileage.Life is to short and if you can't afford the gas you shouldn't have bought the car.
I'am going to fill up now so have a nice day!
