Will be filling up in the morning with fingers crossed this is an anomaly, cause that would be awful gas mileage for a mostly highway driven DD, usually with cruise on. No, I don't worry about gas mileage, but this really poor rate (based on my driving habits) could indicate potential fuel line issues somewhere, since it is on a car with only 1700 miles on it and not tracked or even hot rodded...Shell premium, so not the gas...
Filled up on way to work this morning and car only took 14.12 gallons (and was showing quarter tank on gauge again). Quick math tells me made 19.62 miles per gallon. Last full fill up was 10 Jul and showed 20.01, but I was in break in period and trying to not exceed 4k rpm. So all appears okay, just wish gauge wasn't so flaky with 5 gallons left in tank...another 100 miles is 2-3 extra days I could go between fill-ups! Maybe as I own the car longer and learn it's nuances better, I'll feel more confident relying on on odometer/distance driven...or I'll just resign myself to filling up at 1/4 tank remaining.
