***MPG before and after stereo install... WTF***

[SHOnOFF 10+ year member]

Dayummm i went from 17 miles per gallon with my stock f-150 with a 4.6 V8 down to 12MPG after adding almost a 1000 pounds of stereo equiment and 300 lbs of new 23" rims and tires.

WTF.

did anybody notice anything like this or is my new wheel diameter messing up my " mileage" in reality or just tricking my computer and make it look like i'm only that little now. any ideas.

tires are properly inflated to manufac specs. and no engine lights on.

Those wheels take a lot more power to get going, especially in stop and go traffic. I noticed a decrease like that on my 5.4L F150 as well.

i'm not *****ing about it i can afford all the gas i want. just thought it was odd to lose that much MPG by just adding wheels and a stereo. if i had known that before hand i STILL would have done it. it was well worth its price in gas that's for sure.

After i took my stereo out of my last car i gained 9 mpg. Shit happens.

Probably a 70/30 combo of the wheels/tires and the stereo. 70% being the new rubber, and 30% being the stereo.

I've seen no difference in my gas mileage before and after with my stereo. But it doesn't weigh much either. Maybe 250 lbs all together.

1000lbs is a lot... that's like riding around w/ 10 skinny chicks constantly. what did you expect?

are your new tires outside diamater - larger than your stocks ?

if so then....

your computer is reading 1.3 ish miles as 1 mile.

think like this :

your stock tire = letts say 500 rotations to make a mile.

your new tire = 450 rotations to make a mile since its larger in diamater.

your computer of the car is reading how manny times the tire or drive shaft turns to equil a mile so its off now if you have switched sizes.

plus - for added stress - if you new wheel + tire size is larger than before - your final drive ratio at the wheels is off. so it is now much harder on your ****** and engine to go from stoped to what ever mph. you have effectivly added "highway gears" to your rear end

with the larger tire. this requires more power to start off from a stop, so there is your gas milage down the tubes. on the highway tho, it shouldnt matter much at all.

You are also a driving a dinky v8. That engine doesn't have any extra umph to push the added weight. Sounds like you need a regear.
