fuel mileage/elevation

Does anyone know if elevation has anything to do with fuel mileage? Such as higher elevations such as northern nevada where I live which is about 4,400 ft and say california which is right about sea level. I notice way better fuel mileage in california then I do nevada.

Elevation is responsible for all sorts of changes including your fuel usage. Years ago, Mercedes was one of the first auto manufacturers that designed a fuel system that changed with elevation automatically.

Alright, ya I was curious because on the freeway im driving the same speed in nevada and in cali, and I notice almost 2mpg better in cali. Also flatter ground in cali im sure has alot to do with better mileage compared to all the hills in nevada

Everything comes into play. Barometric pressure, fuel quality, temps etc.

I think I'm going to throw my hat in the fuel quality ring......I've got to imagine Cali has different specs on fuel than Nevada. But that's just my very uneducated guess.

P.S.

The only reason I speculate.....we must have switched to some other "Blend"....perhaps winter....and I've noticed at least a 2 mpg decrease running in mixed driving.

2011 F 350 Lariat Ultimate CC, SB 4x4 with 6.7 PowerStroke. Sterling Grey Metallic. Stock rims, tires. Shocks are Bilstein 5160's...what an upgrade over stock!

2013 PW Boss Mustang with aftermarket fully adjustable suspension, Team Dynamic 18"x10" race wheels and 305mm Continental race slicks at all four corners....O/R X pipe, 84.5mm TB, Airaid cai, 47 lb injectors...tuned by AED...Life is fun in this vehicle!

Now this is just from a 7.3 but still kinda applies:
Pulling an 8k lb fifth wheel up to Colorado, Utah, and the area, I've noticed better mileage.
