My MPG sucks first 1k miles

[Emarc]

I have around 800 miles on the truck. Almost all my driving is city driving 4 miles to work, 4 miles home for lunch, 4 miles back and 4 miles home. About once a week I take 50 mile interstate driving trip. I am in Florida, it has been in the mid 70's for the past 10 days.

I am averaging. 12.5 on the current tank. 15 MPG lifetime and I think the only reason it is that high is because it was a dealer swap that had to be driven here.

Could this just be because I don't drive that much? My truck has zero mods...right now

No doubt the 4 mile city trips are a big contributor. Not having any miles on likely also has an impact.

About what I get on mine, those 4 mile trips definitely hurting rather than helping mpg's.

funny, I have the same city commute (about 4 miles) and I also drive back home sometimes during my lunch break. I get 14.5 to 15 mpg. Which is better than some F150 crew cabs I had that only got 12 to 13mpg same commute.

 

I got 21mpg on an all highway trip. This was with under 1k miles on the truck. I've had the truck 3 months now and it just rolled over 2k miles. Lifetime mpg is 16 according to OnStar app.

I'm dealing with the same thing, very short commute to work so I average about 10.5 city. Frustrating as hell because i get about 19-20 or so on the highway. But the city is killing me. No idea where they get 16 city mpg from, but that's definitely not what I see. 5.3 All Terrain SLE 20" rims SRA stock tires. Everything stock.

I guess it is what it is. Makes me feel better that it isn't something wrong with my truck.

remote start kills your mpg as well as idling at any lights. my commute is all city and i get about 12mpg average but can get up to 16-17 if i baby it. 6.2L

My MPG have been getting worse since picking the truck up. Anyone else notice that?

[stevev]

^I believe winter blend gas is out now so it can cause a drop in mpgs.

[fondupot]

Short trips are bad for MPG. Doesn't let the motor warm up. And its even worse if its stop and go for 4 miles.

[jonny24]

Feeling a little better about mine now. I was getting kind of ok numbers, but the last couple weeks have sucked. I'm hoping its a combo of winter gas and remote starting. It's 90% country driving, you'd thing I'd be getting at least better than city numbers. City is 13 l/100, was at 17.2 this morning. I've never seen the advertised 9 l/100 hwy except when going downhill.

[Ride.Safe]

My mileage is between 13 & 14 MPG with a 7 mile work commute and sometimes I have the truck idling as a remote start with a 1000 miles on the OD. Taking the truck on a long trip and I'm anxious to see how it does on the long trip.

Well I am averaging 16/18 with mud tires and a level kit. So far the lifetime is at 16 mpg. Before my tires and level kits I was running 18/22 mpg.

[colton_m]

I'm averaging 15.5mpg, 10 miles back and forth to work each way. 18-19mpg on long highway trips. I've got the 6.2L, level and AT tires tho... I hope your mileage improves.

[Spurshot]

I'm in the 15-16 mpg for the 10000 miles I've had it. Almost all "city" with some city freeway stuff in there, which can go from the Tijuana Grand Prix to stop n go.
