I get 56-58 mpg on my WRR. So far it is stock except for a 12T front sprocket. I weigh 220# and usually haul about 10-15# worth of stuff, I ride about 50/50 on/off road (hours not miles) and am usually in the upper half of the rpm range. I run 90 octane (best there is in these parts unfortunatly).

1- What do others get, include before & after mods, rider/gear weight, fuel octane rating etc.

2-When you calculate mpg are you adding the low fuel odometer miles? I'm not because I believe that the standard tripometer continues to count when the low fuel light comes on and adding the two meters would give me a false mpg calculation. Somebody please verify this if you would.

I usually get about 62-63 on my WRX ridden 90/10% street/dirt.

She has a K&N filter and powercommander.

You don't need to add the low fuel mileage counter. The trip meter will keep a continuous count from whenever you reset it last.

Stock, street riding normally, best was 84 mpg. Worst was 68, offroad, riding REAL hard. Normally riding offroad with some throttle cracking fun I'll get as low as 76. With tuner/pipe/airbox, best 82, regular street riding. Worst, 75 offroad. Run 94 Chevron hi-test, and I fill up when my light comes on, and don't add in the F miles after.

I usually get around 65 mpg. 90% street.

Normal: 61 - 65 mpg (U.S. gallons)
Highest: 69mpg
Lowest: 55mpg

I normally get 61 - 65mpg (U.S. gallons) whether I am commuting 16 miles back and forth to work with cold starts, doing long, fairly high speed rides on the tarmac, or hammering it in low gears out on the trails. Two exceptions have occurred outside of that bracket. One high. One low.

I once got nearly 69 mpg ride where I did an entire tank on an meandering 45-50mph gravel road in high gear. The other exception was a hard trail ride while in MN (near sea level) where I only got 55mpg; my lowest mpg ever. My other two tanks of gas, near sea level, were up in the usual 60mpg range, but those were country road cruising where I would have normally been up around 65mpg. In MT, my usual riding altitude is 4,000 - 6,000 ft.

Total weight of rider, gear, and full dirtbagz is usually around 190lbs. Bike is stock in regards to anything that would impact mileage (exhaust, programmer, gearing, tires, AIS/EXUP, speedohealer, etc.). I'm calculating mileage using the stock odometer reading, so that might throw my "calculated mpg" vs. "true mpg" off a bit.

I try to run premium when available, but don't worry too much about running mid or regular if that is all that is available, especially since real summer heat hasn't kicked in here, yet. A few days in the 90s, but we haven't had the usual July 100 degree heat yet.

It seems there is a wide variance in reported mileage, which is common with any other bike-specific mpg thread. Differences in riding style, factory build, break in style, gas quality, altitude, rider/luggage weight, aerodynamic changes (windshields, saddlebags), and especially bike mods, like gearing, tires, FI programmer changes, etc leave so many variables, it's tough to say was is normal mpg for a specific model. It's still interesting to see everyone's reported mileage, though.

500 Miles On Wrx. All Street Riding On It. Q4 Pipe At 300 Miles. No Change In Mpg With Pipe. 13 Miles To Work One Way. Mostly 55 To 75 Mph With Some Stoplights. Average 67-68 Mpg.
