Hills and heavy loads are good reasons to get a diesel. Economy and performance suffers more with a gasser under loads. Short trip city dwellers would benefit more from a gas engine. Our diesel needs to be driven and worked to realize the advantages.

Re: Eco Diesel Mileage

Regina, this will be my first winter with the diesel KGC-- we live in Minnesota. I am sure there are other readers heading into their first winters in cold climates. Do you have any tips for winter starting, etc? We have the heater cable. Did you use it, and if so, at what temperatures? Thanks in advance for your advice.

Re: Eco Diesel Mileage

This will be my first winter with the WK2 diesel but I had a WK diesel for several years. I'd use the block heater when parked out side if the temp was under 30 degrees - just as a precaution as I use them on my gas vehicles as it makes start up easier and you have heat much faster in the vehicle. It also saves on fuel as the engine doesn't have to fast idle as long (to get up to temp).

Most of the newer vehicles work fine in the colder temperatures and the the GC is no different. At -4f we generally start to plug in our vehicles but during the day it is not always possible. Last year was extremely cold and there were many days where the vehicle was in -22f to -40f weather not being plugged in for 6-8 hours, it started and ran fine. (Just let it warm up for a while before driving, watch your oil temp gauge). I only had/have 4 winter issues. 1. Colder than -4f the remote start did not work all the time. Dealership couldn't find anything wrong. 2. The first cold snap below -22f the GC ran like shit (sputtering) and I was upset but found out it was probably fuel related and switched gas stations. No issues since. I just talked to a lot of truckers and guys with diesel trucks and found out where they filled up. 3. The fibre inner wheel wells can collect/accumulate snow and slush in certain conditions. If you notice it happening park in a warm garage or go to a car wash and spray it off. Mine are getting replaced by the dealership as they are in poor condition now (Cracked and split) once the parts come in. Would love some improved after market ones. 4. Air suspension developed a leak. Fixed under warranty. I suspect operating the easy access lowering mode in -40f was not a good idea. I will disable that feature when it gets cold as well as when there is some hard packed snow where you park. My GC lowered the front air dam right on top of frozen ridge from the city's snow removal service and crushed it. No issues at regular ride height to park but be careful when it lowers, luckily no damage but if it was a bit colder I am sure it would have cracked or snapped some fasteners/rivets.

It was an excellent winter vehicle, maybe not as rugged as I would have hoped but some simple mods should help that. Love it though, especially the heated steering wheel.

Re: Eco Diesel Mileage

Drove from Oklahoma to Montana and averaged out to 28.2. I was generally driving 75-83 mph. Couldn't be happier with the mpg considering the hills in Wyoming and Montana. As others mentioned, if you keep the vehicle in the 55-60 range the MPG rises dramatically. The range on this vehicle between fill-ups is incredible!

Re: Eco Diesel Mileage

Have 10.8k on a 14 GC Limited 4x4. Best case, 32 mpg for 200 mile trip from VT to MA. Usually average 28-30mpg. Highway and City driving difference is around 2-3mpg Towing a 29 foot travel trailer we get 15-16 mpg.

Re: Eco Diesel Mileage

I changed tires in Feb to 275/65/18 and figured out I lost about 2-3 mpg

So having said that, I'm 19-20ish city and 28-29ish highway.
