Anyone using one during the winter months? We've been in full winter mode the last few weeks. Nigh time temps have been in that 5 to -6 range and as low as -22 so far. I just wanted to share an observation, see what everyone else with a 6.4 in cold weather is witnessing. Pulling our snowmachines (~2500k#) 20 miles home last night it was 3 and truck oil temp never got above 195 on the digital display. I idled it for 20 minutes to warm the cab up before we headed down the road. Cab heat is good, no problems there. Coolant temps on the digital where the same as the oil, which, after warm up, are usually 10-15 degrees cooler than the digital oil display. I've always seen that oil temps are 10-15 degrees lower when the air temps are cold and efficiency (mpg) goes downhill. It seems there is an air temperature range around 20-25 degrees where the truck hits that 205 range where it is most efficient. Its just real noticeable in cold air temps and I was thinking that I would see oil temps above 200 when towing due to the added resistance. Any thoughts/opinions out there? Thought a winter cover may help.
