Was wondering what some of you have been getting for mileage now that the temps have been droping as we aproach the start of winter. I live in southern Ontario and normally calculate km/L but I did some conversions.

Currently getting the following mileage:

5.8km/L = 13.67mi/US Gal = 16.39mi/Imp Gal

I'm sure its gonna get worse before it starts to get better again.

 

worse? maybe...you're running in denser air. I would think that you would start getting better millage. What does your tire pressure look like?

 

"worse? maybe...you're running in denser air. I would think that you would start getting better millage."

Someone correct me if I'm wrong but the denser the air the more fuel is required to maintain the correct AFR. The thinner the air the less fuel is required.

All 4 tires at 40 psi.

 

In addition to the denser air (more drag):

1. Winter blend gas
2. Longer time to optimal operating temp
3. Idling (gotta be toasty before we get in)

etc...

Thanks for that link shotgunz. I like the way it starts off "another reason to hate winter"

 

cool, that's good info. I used to get better millage in the winter in my old Tahoe. That's mostly what I based my first post on. I probably just thrash the throttle more in the summer

 

I get better gas mileage at high altitudes - air is less dense.

 

I get around 20 to 33mi/Imp Gal ... 33 when on the highway. 20 when stuck in the city ... TO to Brampton daily to work.

I found using 91 octane from Shell or Husky, which has no Ethanol, gives the above milages constantly. The 10% ethanol blend gives about 10 to 16% worse milage. I don't tromp on the gas pedal ... and stick to around 90 to 110 km/h.

 

How can you possibly get 33 miles to the gallon on the highway with an FX4??


explain your method...

 

freewheeling downhill, being pulled up the other side with another FX4!!!

 

 

Lie-o-meter has been pretty consistent between 12-13 l/100km (means nothing to me, damn metric)
19.6-18/US gal. = 23.5-21.7/Imperial gal. Combined city/highway, 5.4, 2 wheel drive.
Formula jg, that mileage kinda stinks. I'm in southern Ont. as well.

 

rufas,
I had a feeling my mileage sucked thats why I posted this thread to see what others are getting.
Do you manually calculate your mileage?
I have only used Sunoco 87 octane (now PetroCan) maybe I should try another brand.

 

I keep around 90 to 100 km/h ... also use Shell 91 or Husky 91 which is 100% gasoline ... no ethanol. With 87 + ethanol I get around 14 liters/100. 8 per 100 = 33 Imp/mpg. I don't tromp on the gas ... and take it easy. Usually running in 2 WD ... 5.4 with 3.73 rear ...

Sticker shows close to 29 mpg on 87. The 2010 and now the 2011 have improved the mileage ... including a 6 speed transmission.

 

Look for a gas station that does not have ethanol. There are a few around ... hard to find. Ethanol has 85 to 89% of the BTU's that pure gasoline has. This cause the mileage to drop. Switch to pure gasoline and you will improve the mileage by about 10 to 20%. In my case it's close to 20% which makes the change to 91 (pure gasoline) worth the extra cost. The only stations I know that have 91 pure is Shell and Husky. Look at the pumps or on-line at their respective web sites.


Temp here has been in the plus, usually around 5 C. Not like out west ... so the mileage may decrease when it gets colder. Most of the readings have been around +10 C or so. Recently it has dropped to +5.
