Dumb question on mpg

[xanatost]

How do you figure out my mpg? I just did a long road trip in my hoe and I want to know what my mpg is.

Check your odometer before you start, check your odometer after your trip is over, divide your miles traveled by how many gallons you just put in to fill back up.

I put in 28 gal and drove 421 miles on one tank doing average 75 all interstate and stoping only once for food and rest stop. So what you think my mpg would be?

 

[gpracer1]

421 divided by 28 = 15.03 mpg
Sounds about right for that speed.

15mpg. I usually get 18 hwy. got 13.5 pulling a small trailer at 80 last trip. I check my mileage every fillup to make sure nothings gone screwy !

Fill it all the way up
Trip Odometer to zero
Drive
Fill up completely again
Divide miles driven by the gallons of gas used


I can get 17-18 mpg if I drive around 70 mph, 15-16 if I'm going 75-80 on the interstate.

Do you have a TBI or a vortec?

15mpg is about average for a stock TBI or a lifted Vortec with oversized tires at hwy speeds.

A stock suspension Vortec with stock sized tires like Dylan's will do better.

idk maybe its something to do with the police package or maybe my gauge isnt acurate the gauge reads 20.9 on my dash

Is your speedometer right?

Otherwise known as the lie-o-meter.

At 65 mph highway steady flat road I get 20.2 mpg with the AC on high with my current mods.
Now I just need exhaust and roller rockers to finish it.

its off 4mph because of the wheels

 

[yates ™]

its off 4mph because of the wheels

So your DIC is way off. Why don't you change your tire size with the diablo?

i just put jantzer ported tb on and have to move to to Rockford, IL twice this week. i will get a current mileage run on mine for you all. my speedo is off because of tire size but i can re-calc it for you.

Mine has the Z71 package with 32" tires. I really need a oil change. I usely get 450 miles on a full tank.

If I "old man drive" it I can hit 22. I also have the windows down and no A/C, which let's face it, when it's 100+ degrees out, not worth it. Most of the time, 60 mph, easy on the brakes, coasting, driving like a responsible geriatric (which at 26 is NOT easy) I can hover at 18 - 20 mpg on the highway and usually get between 12-15 mpg in town.
