2015 Overland Trip Report

Just got back from a round trip from southwest Utah to Denver, CO.

Total mileage was 1240 miles. Elevation changes exceeded 8000 feet; 4000 feet multiple times. Coldest temperature was -15 deg. F.

My Overland now has just over 2500 miles on it. Average miles per gallon on Winter blend fuel was 26.5 mpg. Top speeds were around 85 (Utah) and 75 (Colorado).

Car was loaded to the gills both ways; did not weigh it but there had to be over 300 pounds of "stuff" in the car not counting the two occupants.


Comments:
I used a cold weather fuel additive to keep the fuel from gelling as the car was stored outside in the Denver area for 8 days. Night time temps. got down to -2 deg. F. and always below 10 deg. F. every night. I did plug in the engine heater on nights where I knew I was going to use the car the next morning. Oil temps. were 35-40 degrees at engine start.

The car did well on the long steep grades; both up and down. We hit packed snow, slush, ice and melting snow in many spots. Other than getting a salt bath and slushed up, traction was excellent.

The car climbs like a mountain goat...glides up and down steep grades better than any car I have owned or driven. I had to watch my speed even on very steep (12%) grades as I was blowing past many other folks without even trying.

The only issues I had was damage from one truck that must of just gotten off of a gravel road. I had two rock chips in the windshield, one on the hood, one on the driver side mirror and one below the grill. It was sudden and no avoidance was possible so I got a gravel bath.


Overall, I am happy with the car and the performance on our first real trip; especially in the cold and all the issues with diesels in the cold. I was impressed with the mpg despite having a heavy foot crossing most of the Rocky Mountains (I-15, I-70) and many elevation changes in very cold conditions. The Cooper Discoverer ATP tires were excellent on all road conditions. I have significant back issues and the seats were surprisingly comfortable for the 10 hour drive (each way).

Great car...great performance..great mpg...great comfort and I even like the color.

Great trip report. I live in Utah and am headed to the springs this weekend for a quick trip. I'll see how mine does.

Re: 2015 Overland Trip Report

Thanks for the report. I also just switched to the Cooper ATP and I am making a trip from Houston-Denver-Salt Lake next week. Good to know everything went well and that I shouldn't have any problems.

How cold of a start did you have without the block heater? I don't have the cord and wasn't planning to pick one up for this week long trip. Manual states down to -20 should be fine, I'll just be cold for a while until it warms up.

The coldest I tried to do an engine start after sitting in the cold all night was 5 deg. F outside temp. I never started it without the block heater going for at least a couple of hours. It started just fine...just had more diesel "rattle" than usual for a few minutes as the oil got moving. Oil temp. was around 35 deg.

My biggest concern...not getting oil on the cylinder walls and other moving parts. I treated the diesel fuel to make sure it would not gel but the engine oil was my worry for really cold starting. My other diesel is my 400 hp Cummins ISM in my motorhome. I also use a block heater in it when it gets under 20 deg. F outside.

I see no reason to stress a brand new engine with oil starvation.

Good luck on your trip. Drive careful...way too many nuts out there on the road these days.

Re: 2015 Overland Trip Report

In the previous winter in Minnesota I started my Jeep at -15 degrees several times without using the block heater. It didn't struggle starting up, so I wouldn't be worried at all about temperatures in the single digits or just below zero.
