Fill date Distance Fill amount Price MPG Details
2009-02-14 282.8 mi. 15.95 US gal $1.739 17.73 US All in town stuff, never once (I mean never) above 50mph, mostly 20-40mph. Terrible, cold, short trips, needs oils changed, plugs and wires, radiator fluid flushed and replaced, new thermostat, the list goes.

Poor car. It needs help.
2008-12-03 306.8 mi. 16 US gal $1.699 19.18 US All city, not even a hint of highway speeds. Drove up a mountain road, kept it in 2nd because of snow and ice, so at times it was rolling 3000rpms for extended periods. Plus the last 1/4 tank was total hoon action. It snowed 5-6 inches, I couldn't resist taking it for a few spins!
2008-11-11 478.5 mi. 15.61 US gal $2.159 30.65 US Trip to Missoula and back to get a bike. Sad that driving was cheaper than shipping. Ah well. decent enough mileage.
2008-11-06 332.5 mi. 16.38 US gal $2.259 20.3 US Cheap gas, I can make 1 tank last 3 weeks, even when driving 4 out of 5 days to work.
2008-10-14 312 mi. 15.13 US gal $3.089 20.62 US Had a lapse in data logging, but I've started again.
2008-07-06 383.9 mi. 13.06 US gal $4.059 29.4 US From CDA to Bozeman. I didn't drive, if you couldn't tell. I was too tired, and decided to let the FE suffer, as well as my tranny! good god he made it shift a lot.
2008-07-06 305.8 mi. 9.876 US gal $3.899 30.96 US Seattle to CDA. Going home. I didn't try too hard for mileage, it was super early, and I only had 3 hours of sleep. We also had a time frame to meet, so I pushed it harder uphill than I wanted to.
2008-07-06 441.6 mi. 14.62 US gal $4.379 30.21 US CDA to Seattle area, via Highway 2. Scenic, but probably knocked the FE a little. Also lots of fast city driving, certainly killed the average.
2008-07-04 428.4 mi. 12.57 US gal $3.899 34.08 US Bozeman to Coeur De' Alene. Me driving, 5 passengers with luggage for 4 days. Estimated car weight at 4200-4300lbs. The real distance is 365 miles (some random in-town at the end), took us 5.5 hours. I amazed myself with the mileage and time. Still 100% stock car.
2008-07-02 378.3 mi. 14.54 US gal $4.059 26.02 US All in-town again, maybe 50 miles on 60-65mph highways. Not bad.
2008-06-13 332.8 mi. 15.16 US gal $3.959 21.95 US All in-town driving. Easy on the throttle, off at red lights, neutral coasting as often as possible.
2008-05-25 461 mi. 15.8 US gal $3.749 29.18 US Cour De' Alene to Bozeman. The last 90 miles are in-town driving, averaging 22mpg for those miles, one can deduce our actual highway mileage. (31.68mpg highway)
2008-05-19 549 mi. 17.27 US gal $3.509 31.79 US Technically more than the tank would allow. Stopped early and filled 1.309 gal @ $3.819 in several miles back just in case we didn't make it to my fav Coeur De' Alene station. Coming from Forest Grove.
2008-05-16 301 mi. 10.29 US gal $3.939 29.25 US Forest Grove to Seattle and back. Mom drove, not so great FE.
2008-05-16 414.9 mi. 11.89 US gal $3.699 34.89 US Coeur De' Alene, ID to Forest Grove, OR
2008-05-15 370.8 mi. 11.23 US gal $3.499 33.02 US Bozeman to Couer De' Alene
2008-05-15 219.7 mi. 9.953 US gal $3.569 22.07 US Fill before a weekend trip.
