MPG Advice

[Randy Schmidt]

On 87 Octane I was getting around 13-14 mpg. On 93 Octane I am getting around 16-17 mph.

Most of the driving around town we do is super short trips. Like 1 mile to the store and back. 1 mile to the school and back. Doesn't even give it time to warm up really and mileage is terrible, 13-15. If we drive it longer and get it warmed up it does way better. Longer around town trips see it hit more like 18+. Highway we are seeing 22+. Towing the 5k RV trailer and we see 12-15 on the highway, occasionally better depending on wind and how level the trip is.

I know for sure mud tires on my jeep drop me 1-2 mpg everywhere. Going bigger also drops it.

Interesting ....

I have a 4x4 Plat with 275/60r20 Michelins (which are apparently good for mpg..)

With a uhaul 12' trailer I get ~12-14. Highway I get 21-23 and mix when in town ~18-19. But I have a light foot, enjoy cruising in 2wd normal mode. I have the Mustang GT for the "sporty" stuff...

What he said, except our trips are all between 1-6 miles. I’ll just add that there seems to be a large jump in fuel efficiency once the transmission warms up.

I have the tow package so a low rear end. I'm getting 20 in normal driving. I got 9.something when I towed a 6600 lb Airstream, so that's brought my average down to 18. something.

I don't live in a city and I use eco mode.

Did you also put a lift kit on it with those tires? Both dramatically drop mpg.

On the highway I can squeak out between 9.9L / 100 kms and 10.9L / 100 kms (or 28.5 to 25.9 mpg) driving about 110-120 km/h. In town I lose bit and get about 20.9 mpg or about 13.5L / 100 kms.

You are using the old Canadian gallon which does not compare the the US gallon the other guys are using. A Canadian gallon is 4.546 litres where the US gallon is only 3.785 litres.
Using the US gal these are the results.
9.9 l/100km is 23.75 mpg
10.9l/100km is 21.58 mpg
13.5l/100km is 17.42 mpg

Wait...gallons are different depending on where you are? I knew we Yanks were beating our own path with the imperial system rather than the metric, but I had no idea things like gallons were different.

What do your milk jugs look like?!?!?

Mind=blown

DAMN YOU UK GALLONS....

New 2019 Platinum 4x4 is only getting average 12.5 mpg. I do have after market mud tires. Anyone else getting around the same or better mpg

Are your mud tires the same diameter as the factory tires? 12.5MPG is atrocious. I don't think I've ever gotten less than 20MPG except while towing.
