Dont forget ppl make up shit on the internet. lol Altitude doesnt have that much affect.Don't forget that @NMhunter lives in Albuquerque, which is around 5,300' elevation. Altitude can have a marked effect on fuel economy.

Uh, ok.Dont forget ppl make up shit on the internet. lol Altitude doesnt have that much affect.
"In the case of gasoline engines, the lower density of air at higher altitude leads theoretically to a decrease of fuel consumption due to the lower negative loop of engine operation due to the decreased frictions due to the wider throttle opening."
It's not just the decrease in fuel burn, it's also decreased wind resistance due to the lower air density. It does make a difference. I drove my EcoBoost Mustang westbound (against the prevailing winds) across I80 in southern Wyoming at 90+ mph for almost an entire tankful of gas and saw better fuel economy than the previous legs of the trip driving at 75 mph across Missouri and Nebraska. Most of I80 in southern Wyoming is above 6000' elevation. Elevation in eastern Missouri starts around 500' and ranges up to around 3500' in western Nebraska. I averaged 27-29 mph at the slower speeds in MO and NE, and 34 mpg in WY. I kept a spreadsheet, so I'm not making shit up."In the case of gasoline engines, the lower density of air at higher altitude leads theoretically to a decrease of fuel consumption due to the lower negative loop of engine operation due to the decreased frictions due to the wider throttle opening."
Theoretically. Its probably minor, like I said.
I have found in my numerous travels driving out west at higher altitudes, Wyoming, Idaho, Utah, Colorado, etc. MPG is better under those conditions.It's not just the decrease in fuel burn, it's also decreased wind resistance due to the lower air density.

If his claimed 28 mpg is stop and go around town driving i don't see that happening.Dont forget ppl make up shit on the internet. lol Altitude doesnt have that much affect.
But he said 28 mpg around town driving not on a trip.It's not just the decrease in fuel burn, it's also decreased wind resistance due to the lower air density. It does make a difference.

I understand, but "around town" means different things to different people. Stop & go traffic in LA rush hour traffic is not the same as "city" driving in ABQ. There are a lot of surface streets with speed limits set at 50 mph and up, and low temps average around 50 degrees in the winter. In my experience the two biggest factors affecting fuel economy with Ford's EcoBoost engines is altitude and temperature. Low altitudes & temps mean lower economy. That would make ABQ just about ideal conditions if you're looking to achieve the best fuel economy with a boxy Ford.But he said 28 mpg around town driving not on a trip.
