so, for the entire winter i averaged about 31mpg in
my integra GSR. i installed a partial front grill-block in march and my mileage immediately jumped 1-2mpg, even with cold temps and driving fast. for the past 2 months i have kept it at 32-33mpg.
this week i decided to slow down and change my driving technique slightly. i kept the speed at a constant 60mph on 55mph "back roads" (versus 70-75 typically... i know, i know), coasted to stops and did everything i could to avoid completely stopping for lights.
from those changes alone, my last tank was
38.03mpg average. ~5mpg increase from an already high 32-33mpg average. this tank was about half highway cruising at 75mph. my gearing is so short that i'm revving at 4200rpm at that speed, just before VTEC engagement.
i'll be very interested to see what next week's tank looks like
here's my
gas log
note: mileage all adjusted 3.3% because i have civic sized tires installed - 195/50-15 vs 195/55-15 for integra
