Gas mileage for Road Glide

I have a 2006 RG with a stage 2 big sucker, rineharts true duals, and the 95 cam performance kit. I get 180 miles per tank og high test with 10% eathanol. Is this fairly typical? I checked the Power Commander III map and the numbers are much higher than the references on thee PC site. I can post my map if that helps.mapping

Sounds a little low and if you mean that you are only gettin 180 ,is that when the light comes on if so your gage for reserve may be off
I also think thats why harley went to the larger tanks
I always complain about my fuel after i been riding at speeds in excess of the posted .LOL
I travel for a living and I like the ethenol blends on regular and I guess I never realized that it was available on the premiun gas which is what I run and harley recomends
The big scam in my book is "Oxynegated" fuel what a bunch of crap that is LOL

I'd like to hear some feed back on gas mileage with specific combos also.

My 2010 got 200 miles per tank stock. I added V&H dresser duals, big sucker intake and a PowerCommander V, and it dropped to 140. So then I bought the AutoTune and bumped the cruise air/fuel up to 14.5 and it got me back up to 160 per tank, but I'm still not impressed.

The 2010 is supposed to have a 6 gallon tank, but when my bike gets the light on and says no miles to empty, it only takes 4.5 gallons every time.

Thoughts?

It pisses me off cause thats what mine does too
Its like they left the Positioning/ sensor in the same place for the 5 gallon tank as the 6 (I think the fuel acts as a cooler oer the fuel pump) believe it or not
Unless your riding tank to tank its not a problem

Well, it is healthy for the pump to be cooled by fuel. But still, a gallon and a half of useless capacity seems overkill.

I'd be curious to hear if other 2010 owners (do 09s have the 6 gallon too?) are hitting the light and getting a 4.5 gallon refill.

I'd also be curious to hear what 5 gallon tank owners are getting on a refill when they get their light.

Gas mileage for Road Glide

In response to your question, the 180 miles was from overflow (almost) to bone dead empty call CAA for gas empty. The gauge is out 1/16 of a tank. I figure I need to tune the ECM Power Commander III but would want a match on my configuration . I don;t have access to a dyno but I have flashed my Power Commander to update the firmware and have backed up my current map to the laptop. No 2010's arround here. Everyone is into Street Glides so no feedback on the 2010 issues.

Thanks

I've gotten (actually alway been) compulsive about keeping records on all my fleet. I've gotten 42.11 mpg on the first 15,000 miles on my 09 RG. I try and use 91 octane real gas whenever I can, from the same station, and from the same pump, to normalize my readings.

I have an excel file that I log information for every fill up, starting and ending odometer reading, miles driven, how many miles are remaining, (according to the bikes computer) price per gallon, how many gallons I can get in, etc.

It's too big to upload here but if anyone wants it, I'll be happy to send it in an e-mail if you PM me.

Thanks everyone. It appears I am running about 20 to 30 miles under what I should per tank. Anyone got a RG with my config and has a mapping for the Power Commander III USB? Dual Rineharts, Stage 2 Big Sucker and the '95 Kit.

Running hard, I get 42 MPG. The light comes on an the gauge shows empty with at least 6 quarts left in the tank. I just ignore the gauge, always reset the trip meter, and know that I need to refill at about 240 miles.

With my 2009 Road Glide, I use Gas Buddy to keep a record of fuel used and mileage. After 15,000 miles, I have average 39.3 MPG. I get better mileage if I keep the speed around 70 MPH on Freeway trips. Around town I get about 36 to 38 MPG. I have gotten as good as 52 MPG when I was on a trip and kept the speed at 65 MPH.
