Really Bad MPG, any advice...

I use quilted cause my rear is sensitive

 

is it cotton ply? It wont flush well.

 

I have a septic system so it's all recycled paper ~ thus the quilted...cause paper hurts

 

BAGAHAHAA... I nominate myself as the interweb police..

 

How often should you change your plugs normally?

 

I get 13mpg as well truck is lifted 3" riding on E load 10ply Falken Rocky mountains. I tow 5 days a week.

At first I was upset about the bad mpgs, but came to a conclusion that its a truck with big V6 so I don't worry about it anymore.

 

about time i see others getting 13

 

OP, do you run youir AC all the time? If so, that will have a big impact on your gas mileage.

 

ive got 33's drive 55-50mph every wear i go. dont use cruise control and drive with a light foot. and it will increase dramatically. i can go about 100 miles per quarter tank .

 

I upgraded sizes and have Load E as well...Get around 15-17.8 usually...Should I get my speedomoter recalibrated so I actually know my true miles?

 

There ya go.

That's a lot of rubber, and cost me 2mpg even on my 360hp Duramax. Truck had no trouble spinning that rubber.

Taller tires slow down the speedo so your calculated MPG is lower.
Those are HEAVY tires. That hurts too.

 

OP,

I think that the weight of the tire, and the tread pattern truly affects the gas mileage of your truck. I had duratrac tires load E and they were somewhat loud, heavy and I noticed a big decrease in gas mileage. I just recently switched to yokohama geolander tires that are 6 pounds lighter and have a less aggressive tread which seems to have improved my mileage. Just some food for thought.

 

I'm stock and I get 13.5-14.5 consistently...boooo

 

not sure if anyone beat me to it, but isn't the movie "spaceballs"?

 

Like others have said, check your MPG with a GPS. I think you will also find that your speedo is now accurate. My 08 with 265/65-17 the speedo showed 30 mph and the GPS showed 28 at 60 the GSP showed 57 with 265/70-17 my speedo is dead on.

 

Nah, I am a windows guy. Plus it's been a cold november so no use for AC

 

there were a couple others that got it right. one of my favorite movie scenes "Ahhh, buckle this"

 

Thanks guys. The tires look and sound cool driving around, but i agree they are probably part of the problem, since i am not 4wheeling all that much. Plus I'm not looking forward to driving on the highway in the snow with them. I may suck up the expense and change out the tires, but keep the same size b/c i do like the look.

Thanks for all the tips and feedback everyone!

 

Your tires are whats killing your MPG.. Ive noticed a huge difference in my MPG once I went from regular road tires to my wider A/Ts.. Maybe get some commute wheels and tires?

*EDIT*

I suppose I should read the whole thread and not just OP before I post! Oops!

 

I've been getting about 20 mpg but you guys must consider she's still all stock. There is one thing I have noticed though. When the price of gas goes down so does my fuel milage and it goes up when price goes up.
