2014+ Gas Mileage (MPG) Topic

[NitrosBoss]

Averaging 13.6 mpg mixed driving with roughly 8000 miles running 33x12.50 tires on a 22" wheel

 

 

 

[hutch08]

295/55r20 Toyo AT2 Xtreme on Stock 20's, RC 2/5" Lift/Level. Truck is still under 1000km.



I haven't re-calibrated my speedo so the mileage should actually be a little better than what's displayed. I average 80% highway, 20% city.





According to my calculations... I'm displaying about 3.4% too slow, so that averages me approx. 19.3L/100km or 12mpg!
I'm surprised how horrible the fuel economy is, anyone notice an improvement as they got more miles on the truck?

I saw a slow improvement as I got more miles on mine. I have only seen ppl go that far down in milage with MT tires at that size. Could the low milage also be because it is so cold where you are?

Quite possibly... temps are well below 0*C here, even dipping below -25 on occasion. That's below -10*F for you U.S folks. The cold weather in general combined with idle/warm-up time definitely does help.

I know I personally can't stand the cold. I'll remote start the truck a few minutes ahead of time if it's even just 40-50*F outside. If itwere as cold here as it is inup north or even Canada, I think I'd go on vacation till winter was over [emoji16]

I've put in E85 for the last three tanks and looks like I get between 10 - 11mpgs in this weather (-9 Fahrenheit this morning)

Winter has is upon us and my increased "warm up" time and crap fuel has killed mileage lately.

 

When I do take a road trip back home to MA (about a 2hr ride), I prefer to use 93 octane as I feel I yield better MPG. Typically I run 87 octane in town as that's 90% of my driving.

I just noticed on a drive tonight that the engine would not go into V4 mode until the operating temp reached 210. It may say that in the manual or may be common knowledge but I never knew that. May actually explain some of the loss experienced during cold weather. It took my truck forever to warm up 2 degrees outside.

My 08 does that too... Took it quite a while to switch into that tonight considering it's about 0F there tonight..going down to -8F.

It's actually waiting for your tranny fluid to get up to temp. The colder it is outside, the higher your tranny fluid temp needs to be. On mine in extreme cold 0ºishF it needs to be above 113ºF. That can take 8-10 miles some times. This is my second winter, and if the air temp is around 32ºF, it might switch around 95ºF on the tranny fluid temp. There is a definite correlation between the two temps.

 

In the summer, mine will switch as soon as I get into 3rd gear and above 15 MPH. The tranny fluid is already warm enough, and the engine is no where near 210ºF yet.

Yeah I just noticed that again, I put my truck back in the garage and went for a drive and it was immediately going into V4 mode so I guess the garage keeps the fluid warm enough to instantly allow V4 more.......one more reason to keep em in the garage.

I know I've increased idle time in this weather. The darn remote starter needs to be able to just start the truck when you push the button no matter how many times you push it - two starts for 10 minutes each just doesn't come close to cutting it in this weather.

 

Either they should not limit it to two remote starts or they should've made the truck so it warms up sooner - a lot sooner. Seems like it takes this engine about three times longer to warm up than my old 2000 S-10 and 2003 Trail Blazer.

Yes, the garage definitely helps.

All Aluminium Engine sheds heat very quick.

Avg 19.5 MPG with true dual exhaust, CAI (Airaid), factory tires (soon to be upgraded to Michelins), 28k miles and 93 octane with 60-80 deg temps. 87 octane, below 60 deg temps and mileage goes down to 14-16MPG. Pulling horse trailer......11-12 MPG. Every once in awhile I'll get a good load of fuel and MPG will avg 22 for that tank. Driving 3 hours at 80 mph on freeway from Dallas after duals were installed I hit a "Best" of 26.1 MPG!
