New guy's first tank report

[mirageman]

I just went through my 2nd full tank on my new (used) 09 5 speed sedan. First full tank was a spirited drive using BG44k to clean out the system. Car has verifiable 17,000 original miles, saw very little use, old gasoline from last year probably in the tank etc. Anyhow, changed the oil, tire pressure at 38psi. That tank got 36.5 mpg. Filled it and took it easy aiming for peak efficiency. Drove 457.6 and kinda force-fed 10.518 gallons this morning for a tally of 43.5mpg. This is 100% suburban driving with few red lights, a few more stop signs and lots of moderate hills. I really took it easy going 42-52 miles per hour and shutting off at known long red lights. I could have shaved just a bit more corners here and there though. Last bar fast blink is supposed to be approximately 1.1 gallons in the tank, so when that happens, you know you burned very close to 10 gallons since we have 11.1 gallon tank. I was at 451 miles when that happened, so I thought I was going to be at 45.1mpg, but alas, the gas gauge is not perfect, or perhaps the gas station pump or both. Happy. Would love to see what I get on the highway.
