New Ranger, Poor Mileage so far...

[Deleted member 15875]

Yes, in fact I HAVE driven down I-17 from Flagstaff to Phoenix many times in both a tractor trailer and my automobiles...but never at that much speed. pretty much everyone here says their fuel mileage starts to go noticeably south above about 72 mph or so.
I was just making an observation based on your dash shot. Higher speeds typically do lend themselves to poorer fuel mileage.

There you go.

Because I don't like to be thought a liar, I took a couple more pics of my dash to show what kind of mileage the truck says I'm getting.
Upon arrival at Costco this morning:

After fueling:

Upon arrival at work...didn't quite retain the 28mpg I had when entering the driveway, with deep apologies for lack of clarity of pic (27.8 mpg):

Think your stock dash is better than mine... It must be one of those production exceptions ...one great spec'd dash that got thru the assembly line with exceptional performance... Kinda like my old Toshiba 30 in CRT TV... When my controller broke 16 years later... I got a hold of a tech that was amazed my TV was still performing great... Said it was known that there once in a great while an over performing spec'd TV that got thru the production line....
Perhaps after several 1000's of miles my Ranger will get better gas mileage...
But not waiting... Getting performance tune sooner than later... That should fix it...better MPG... Or maybe not ...as I will probably have to then...with the extra HP and Torque...drive barefoot or switch to sandals instead of my hiking boots to alleviate "2 Mas El Lead Footoe"... Maybe I"ll invest then in a lap timer... Measure my times to work .. to mom's...the local bar... More time to get there should be better MPG right?

So the goal is to have the most ethonol to get the best mileage?

I think you’d want the least amount of ethanol to maximize mileage. Not sure about the difference, but going from E-10 (10% Ethanol) or E-15 (15% Ethanol) to 0% should some sort of improvement

Nah, it's not an exceptional dash. It's just me using the cruise control a lot and driving like an old man here in PHX (which means staying reasonably close to the posted speed limits and letting the engine and tranny do what they're designed to do).

Nope. The goal is to have NO ethanol. Not only is ethanol bad for engines (and the environment), it actually lowers your mileage because alcohol has a lower heat content than gasoline by volume.

E10 reduces fuel economy by 3% to 4%.
E15 reduces fuel economy by 4% to 5%.
E85 by 25%.

Nothing nearby for me for finding an ethanol free gas station.

It depends on the region. When I lived in a large city that had a large pipeline terminal, all the fuel always had near 10%. Where I live now, we're far from much petroleum infrastructure, so I suspect that most stations have no ethanol in the fuel, even though they are required to state that there may be up to 10%. (Ethanol is usually mixed in at the terminal where the fuel is picked up; it can't be sent through pipelines)

I had a late-90s Mountaineer with a 5-litre V8 that went from getting 16-18 on the highway to 20 traveling in the mountains at 70 mph. I suspect that it was a lack of ethanol in the local fuel supply that was responsible.

I was just reading about someone claiming to get several MPG more using Shell gas. I'm now I'm becoming more curious.

Since I spend time with after-market tuned ECU's in my MC's, most tuners tell me that fuel coming from gas-stations is terrible. We often run expensive fuels in our bikes, like VP Fuel for example. Some of their oxygenated fuels produce 3-5% more power and you definitely can feel it. It's basically like running crack. You never want to run anything else, so I eventually weened myself from that stuff. My pocketbook feels better now.

Just got back from about 900 miles of driving. Mostly 70 mph highway miles with rain and wind. Winter gas blend 87 octane 10% ethanol averaged 23.1 mpg. Same type of driving with summer gas 87 octane 10% ethanol yielded around 25.5 mpg. It looks like winter gas cuts my mpg by 10%.
I thought with a turbo there would not be a big difference. Do all states switch to winter blend or is it a NY thing.

 

[Grumpaw]

I would think that everything is switched over to a winter blends simply for economics....would cost an excess for refineries and stations to have two separate deliveries and storage of separate fuels.

 

[Montana Ranger]

It's regional. Different states/metropolitan areas have different blends.

 

[pbethel]

Why would a turbo help with winter blend fuel?

2021 Tremor here with 11k and change on the odometer. This is what my computer is calculating on the current tank and lifetime average.

Current tank of 87 octane e10

Lifetime average

You can see my average mph is in the low to mid 30's. When i manually calculate each tank, i generally find the computer is between 1-2 mpg more than actual mpg. I've experimented with 93 octane e10 for a few tanks and didn't see a notable difference in mpg worth spending the extra money on.

I have a Roush, little over 2000 miles and I'm getting a dismal 13 to 14 MPG in the city, just terrible MPG so far, any one else with a Roush getting poor gas milage? Does the Fox 2.0 lift and General Grabbers AT/X really kill this much milage?
