Long trip gas mileage results - 5/12/2008 9:08:41 PM    JayhawkinIdaho Posts: 103 Joined: 12/9/2007 From: Idaho Status: offline Hello everyone, I haven't been here for a while. Still have all 3 of my Rovers but sadly going to have to sell the '88 Classic. Last summer I took my '01 Disco from Boise, ID to Wichita, KS and averaged 18.2 mpg. Last weekend, didn't think it could be done, but my wife drove her '95 by her self from Boise, to Omaha, (we are in the midst of relocating), and she got an amazing 21.15 mpg. When she left I gave her specific instructions as to not go over 2800 rpm as I have mentioned in other posts. Believe it or not she followed the instructions, however in her rig, 2500 rpm happens to be about 74 mph. She averaged the whole trip through WY and NE at that speed (even with the cross winds in WY). She drove straight through except for a 4 hour break. She used premium gas the entire way, as per my instructions. The only difference with her truck vs mine is that when we got hers, I had to change the plugs and wires. This was before I knew about using Bosch plugs and Magnicore wires and this forum. I put in Autolite plugs and GM 8mm custom wires for a 350. The tires are also above standard size 245 75 16". I don't know if I got lucky, or we just have a great vehicle, and did finally get the radio fixed, (a relay located inside the left front kick panel). A properly tuned vehicle and a little maintenance will go a long way. Her's was a great find, a 1 local owner when we got it nearly a year ago, with 115K miles on it. It ran rough after we bought it, but after the changing of the plugs and wires it has been a great vehicle, and surprises me every day. Thanks to everyone's help here. _____________________________ Jeff jliechti61@cableone.net 01 Disco 2 SE 60K 95 Disco SE 7 115K 88 RR Classic Former RV Manufacturer Service Manager Post #: 1

I drive to Seattle Wa. every year and going to and from my mileage stays the same on I-70 or I-80 from Tx to Wa. _____________________________ I do not need the National Geographic channel I just look out the windows of my Land Rover Discovery code name Romulus Prefix-N or 1996 Classic Discovery, RPi remapped ECU NRP Preformance cats/Y-pipe (in reply to NiteTrain) Post #: 7

RE: Long trip gas mileage results - 5/14/2008 10:40:48 AM    Mark G   Posts: 282 Joined: 9/15/2007 Status: offline I was going to post about the elevation change too, but besides coming down the foothills, the change is spread out so far, I don't think it would have a profound affect. I drive to/from S. Dakota every year, sometimes a couple times a year, and one thing that IS a factor sometimes is winds that seem to almost always blow towards the east. But I think he said there wasn't any wind on his trip. I know when I came back from Colorado, one problem I seemed to have a lot was getting the tank full. Sometimes it didn't seem to take the amt of gas I was thinking it would, other times it would. So I was showing these wide swings in MPG calculations. _____________________________ Mark G 1998 Disco, 135k mi. (in reply to Landzu) Post #: 8

There are a lot of elevation changes from Boise to Omaha. The first major elevation change is north of Ogden, UT, climbs to around 7000 ft over 12 miles from about 4200ft. Then the western part on I-80 in Wyoming, the "twin sisters" which are up and down to from 4500 to around 6000 ft or so. Then the last major pull is leaving Laramie, going east to Cheynne that you climb to I think 8600ft. She did tell me through quite a bit of Wyoming, as normal there was some cross wind that did keep her awake, and then of course western Nebraska, you never get away from wind.  The only complaint she had with the whole trip was the cruise control would work about 10 miles and then just quit.  _____________________________ Jeff jliechti61@cableone.net 01 Disco 2 SE 60K 95 Disco SE 7 115K 88 RR Classic Former RV Manufacturer Service Manager (in reply to Landzu) Post #: 9
