I have read some posts on the fact that the cold weather brings winter blend fuel to the pumps. This intern means poor mileage in the V5x2. Does anyone know of an additive that will combat the winter blend fuel and return mileage back to the numbers we see in the summer? Or do we have to wait for the spring thaw? Thanks in advance.

 

you are stuck with oxygenated fuel until january.

 

I won't try to say this is part of YOUR problem, but if I lived in Billings, my mileage would super-suck!!! Getting 0 MPG while waiting for the truck to warm up really kills the average.

 

January... Winter starts in January

 

the western states only have to have oxy fuel from october 31st thru january 1st


P/S winter starts in december.

 

December, heck I think the four seasons of ND are: Almost Winter, Winter, Winters almost Over and Road Construction, lol. My mileage usually goes to crap in september, thats when hunting season begins and I can tell you that your mileage when puttsing down prairie trails is near 0, it's kinda like Idealing in the driveway. I don't know the last time I made over 230 miles to a tank!!! I'm guessing it was before labor day!!!

 

is that a 29 gallon tank or a 38?

 

I thought gas was oxygenated in the summer to combat smog/etc ??? Now I gotta look at the pumps, although here I think we have 10% ethanol year-round.

One thing that I have to mention:

Gas mileage sucks in the winter because the air is denser, which the MAF sees, and the computer richens the mix.

I have noticed NO MPG or power differences with 10% ethanol (or MTBE) in any of my modular motors (2x4.6L and 1 V10) vs. 100% gasoline. I've driven upstate and into other states where the gas wasn't oxygenated, filled up, and noticed NO DIFFERENCE.

This has been brought up before, and even in places without oxygenated gas, colder weather means lower MPGs.

 

I've got the short box so I only get the 29 gal tank!! It still hoovers around 8-9mpg. Like I said idling around is terrible for mileage, heck I get 8-9 towing 10k lbs worth of crap at 65-70mpg yet I get the same mileage when i'm out hunting, go figure.

 

we get oxygenated (methanol added) fuel here in the winter. Typically we lose 1-5% of our mpg.

 

Methanol or Ethanol???

 

what ever this garbage is i'm off almost 3 mpgs.

 

I was also wondering about Ethanol blended fuels such as Mohawk/Husky brand. Does anyone have any info on how this Ethanol affects the trucks performance?
