All these impressive mpg numbers make me sad
Best I have ever gotten in my 4Runner (stock 99 with e-locker, so 4.30 gear ratio vs 4.10) is 19.3. This was all interstate, cruise set at 80, two big passes to climb (one of which is the continental divide). I usually keep it around 65 on the big hills. By the time I rolled in to Butte, the low fuel light was on at 250 miles give or take, and I filled up with 12.x gallons. Keep in mind I did a full tune up before this trip, with spark plugs, wires, tb and maf cleaned, TRD tb gasket, air filter, fuel filter, and front o2 sensor.
My usually interstate average is below 18, like 17.8 or so. Around town I get low 15s, but my daily drive to work is less than a mile. I saw high 22s once when I drove from Red Lodge to Butte in the worst blizzard I've ever seen, 4wd all the way, top speed was maybe 50. My girlfriend was following me in her 95 civic dx, so I couldn't go too fast without her getting too uncomfortable.
In highschool, I had a 95 GMC Suburban. 275k miles, burned up to 3 quarts of oil between changes, and regularly got between 6 and 8 mpg. Cost well over $150 to fill the 42 gallon tank

the water pump went out on me right after graduation, so I replaced it along with the thermostat and listed it for sale. Lo and behold, my last tank after the water pump job, I got 13 mpg :mmph:
