Greetings All

Just returned from a 2200 mile road trip with the "85' 240D. Went down to northern CA and did some zig zaging back and forth from way inland to the coast thats why all the miles. Had no problems and used no oil at all. The PO was using Penzoil with some kind of "slickem additive" Arrrrgg! so I switched to Amzoil, changed it after 2500 mls then took off on the trip. Gotta admit its gona take a while longer to get used to the gyrations of the temprature gauge while driving in the mountains. With a "gasser" something would surely be amiss with such fluctuations. I had read lots of archives about the behavior of diesel cooling and I had never taken a long trip in HOT weather through the mountains. The highest it got was over the 100c mark, maybe to 105c on a LONG pull in third gear but most of the time on a pull, not over 90 or 95. Then down the other side she'd drop down below 80c. On the flat at 70-75 mph in 5th she would run at about 85.

I am wondering if you folks with oil coolers experience these sort of temps. Also it seems when I take off in the morning it really takes a couple of hours of freeway driving to get up to temp (85). Of course its nice and cool as I usually start early.
