Follow Up post: Between 85,xxx (Starting) to-88,300 miles ending on Odometer-
I just got back from a 2 day Birmingham to Denver drive, (Stayed 3 days in Colorado) and then returned back on a 2 day Denver to Birmingham drive.
Total mileage for the trip was 3285 including the 3 days in Colorado.
MPG- for the 3285 miles was 46.8 overall. Instead of doing a tank-by-tank average, I wanted real data for an entire trip. This included city-ish driving in and around Boulder with somewhat long stretches.
My best mileage was on the return trip, 53.9 mpg overall for the 1285 miles home. I broke up the trip over 2 days, and didnt need to fill up after the first 12 hour day. I waited until the fuel light came on early in day 2 before filling up. I hated stopping to use the rest room because I watched my tank range drop sometimes 30-50 miles every time I restarted and returned to the interstate speeds after each stop.
The Trip to Denver averaged 51.7 mpg over 2 tanks. 802 miiles on one tank, 737 on tank 2 (including in-town driving while there)
Driving style: Like a Grandpa on the Interstates- Steady Speed- Air Conditioner on 95 % of the time, Cruise Control- and I Drove EXACTLY the speed limit which was as high as 75 in Colorado and 65 in other places. I was careful not to use Bio-diesel blends, and put 6 oz of Power Service in my tank on each fill.
Tires are at 44 psi, Continental Pure Contact. 18" Tires.
Observations:
The car seems to get the best mileage at 63 mph with cruise on. I ran that speed on 150 miles of a lonely dark stretch of East Colorado highway early in the morning on the day I left, and my instant readout never dropped below 60 mpg. Granted, it may have been somewhat more downhill than uphill as elevation dropped from 5200 ft to 3900 ft at the Kansas border.
Anyway, the fix seems to be good on my car.
It seems to like higher cetane than the usual 4 oz of Power Service with every fill up. I experimented with 6 and 8, and there was a difference between 4 and 6 ozs, but no difference with more than 6.
