Well, I said I was going to test the DIC mileage figures on a 3300 mile trip I was taking from TX to NM, AZ, NV, and UT. I kept meticulous records of mileage and came up with 3322.2 miles traveled and 122.012 gal of gas used. The DIC, which I reset as I left for the trip, said I got 28.6 mpg. While there were long straight stretches of desert where my mileage was higher, I did a lot of mountain driving in the Santa Fe/Albuquerque area, the Flagstaff/Sedona area, and the drive into SW Utah. These areas brought my mileage down a couple of mpg. My first long leg from Ft. Worth to Santa Rosa, NM was 29.9 mpg on the DIC. However, when I added up my total miles and the gallons used, the calculator says I got 27.23 mpg - 1.37 mpg less than the DIC or 4.8% difference. I have seen questions on DC in the past about the accuracy of the DIC, so here is a sample of one. :laughing:
Interesting side story. We stayed two nights in Vegas (my favorite place). We stayed at Treasure Island where I have stayed many times before. I valet parked and tipped up front to have the Vette well taken care of. The second day there, we were planning a drive into Utah to check out the beautiful countryside. The round trip that day was about 300 miles. After we checked out of TI and were about to head back home, I stopped to fill up. When I went to fill out my mileage book, I checked my trip odomoter which had been at a little over 1700 miles at the last fill up. It read 89.9 miles! The only way it could read that amount IMO, is for someone in the valet group to reset the trip odo and then drive 89.9 mi. There is no possibility we reset that odo ourselves, and even if we had, it would read 0, not 89.9. Needless to say, I was furious. Another clue was that we had a plastic bottle of orange juice in the passenger side of the floorboard. It had been stepped on, cracked and leaked profusely on the floor mat. So someone had been sitting in the passenger seat. We had already checked out, so I called the hotel, asked for security and filed a complaint. They were going to check cameras and get back to me. We'll see. I checked the car with a fine tooth comb and could find no damage. But who knows how hard they might have driven the car? If you can't tell, I'm still burning over this.
