We just completed a 3361 mile, 3-1/2 week trip from Tucson up through the Grand Tetons, Yellowstone, Devil's Tower, Rapid city and associated attractions, then back down through Wyoming and Utah to Tucson. I had no problems with anything on the coach but I was concerned abut my oil pressure readings on the factory gauge. It never went below the low line (about 1/4 of the way up) and was always higher than that at any speed above idle, but it was all over the place while driving.
The engine has about 12,000 miles on it (now) and used about 1 pint of oil during the entire trip. The trip included SEVERAL 6 - 8 % grades for miles and miles in second gear and topped out at over 9600' elevation. All this while towing a 2003, four door Tracker (~3000#)
My dream is to someday go with a Mac-Dash and have a REAL oil pressure gauge among other things, but for now I would like to get the most accurate reading out of my stock gauge. If I remember correctly, the sending unit comes in two versions, a 60 ohm and a 90 ohm. Which one provides the most accurate reading on the gauge? I currently have a 60 ohm and don't trust it to be reading correctly.
Thanks.
