Does anyone know how much having the truck in 4 high kills you gas millage? It's winter in Colorado and I find myself driving in 4 high quite often so I just wanted to know how much it's costing me. By the way its a '95 xtra cab with the 3.4L.

 

quite a bit. in 2wd my truck gets about 17 around town. in 4x4, ive filled up, gone offroadin in mud in 4lo, and was almost empty 2 hours later.

 

If you are running in 4 hi, it shouldn't be more than a few mpg, but realistically, snow+4hi+lo speed= less mileage.

I got 19 running between Moscow and seattle in the winter-- about 60% 4hi, 40% 2hi.

 

I never calculated it, but a whole offroading trip (the whole day) I went in with a full tank and wasted maybe 1/3 to 1/2 of it. Almost all of it in 4hi too.

 

Well last night I did a 5hr snow trip, engine was off maybe 20 minutes to help a fellow yota owner with a wet distributor on the trail. Overall mileage was around 60 miles i guess.. hard to say, i go by hours when im in the hills.

I started with a smidge under half tank.. and got home w/ a smidge above E.

I average 20-21 mpg highway/town.. 22R.

You cant honestly calculate mpg when your wheeln or on a snow trip. It's impossible. It's a terrible way to figure out a rate of burning gas. I figure I'm burning no more gas than normal. The motor has only one efficiency. Just figure if your putting more resistance on the motor the more gas it will burn.

 

I think he is talking about in town and highway driving while in 4hi...

 

Yes i am talking about just basic around town driving on the icy roads here in denver. Four wheeling would be a different story.

 

I'm in Colorado too with the same truck. In the summer I can get 325 miles from a tank on the highway. In the winter, I usually get 300 miles to a tank. (I always get the best mileage on hwy285 from Buena Vista to Denver). I just guage the type of mileage I'm getting off the 1/2 and "E" mark based on 300 miles I expect before the light goes on. I watched the mileage closely on my last trip using 4 Hi for a chunk of it. I didn't notice a huge variation in the mileage I got. My mileage always craters above 70 miles per hour no matter what I do. I may get crappier mileage because of a big rack frame that goes up and over topper.
What kind of normal mileage do you get?

As for the city streets in snow, I usually misbehave on the gas pedal anyway, so that's not a fair comparison.

 

I'm not sure exactly what kind of millage i'm getting i'm guessing its around 18-20 like everyone else. I am also prone to misbehaving on slick roads which is no good for the gas millage but what the hell its good for the soul right. I recently put a small amount of gas in the tank when it was just about empty and left it in 4 high the entire time until i ran it out. i was expecting to get about 80 miles on the gas i put in and only got to 68 so it does make a noticeable difference but not a huge one.
