Trying to get an idea what the average MPG is on the 1800. Mine has around 10,000 miles on it and is a 03 and I have noticed a drop in milage. Had ECM done a while back. Maybe the Sheets low grade gas I'm using, don't know. What do you guys normally get MPG wise and out of a tank of gas.

Thanks

My '02 1 up averages 43 around town and high 40's (sometimes low 50's) on the open road as long as I keep it below 70mph.

About the same here. I live at 7000' and am not easy on the throttle, but I think my high milage is related to the altitude. If I lived at a lower altitude, I'm sure the milage would drop.

MPG on mine is usually between 40 and 45. A lot depends on your wrist, and as mentioned, altitude seems to effect it also. The higher you go, the better your mpg.

I have always done 28mpg to 36mpg. But I have a wrist.

Just checked my gas spreedsheet for '03. From 3/15 to 11/20 a total of 11764 miles on about 295 gal. = about 39.9 mpg. About 4800 miles pulling the Bushtec. I think the owners manual said no hard or full throttle for the first 300 miles. After that I did not spare the throttle.

my 2002 has averaged 43 mpg for the last 43,000. Has been as low as 29 and as high as 51 mpg.

Hawk, I'm not picking on you, just using the numbers you gave as an example. The odometer/speedometer is known to have a 4 to 6 percent error built in by mother honda. So if we take your 11764 miles and factor in a 5% error your miles were closer to 11176 (11764 X 95%) then divide by the gallons used, we now have a corrected mpg of 37.88.

Do you suppose all the other posts have included the mileage correction factor in their average mpg?

I suppose I'm in the same MPG range as the others who have responded - mid-to-upper 30's. I kept track of such things far more after first getting my Wing, but slacked off, except for long trips. I hope I'd recognize a poorly running engine through performance or sound before I'd do so by checking MPG's. I do like reading about the MPG's the folks at higher elevations are getting, though!

Hey, Hawk, great pics of your '03 Silver and trailer. I'll be watching for you around the Cities this summer.

See what you started Joe...don't even think about asking a question concerning oil...the responses will give you fits.

Hawk, if they don't say it is corrected, I have to assume not. If you posted corrected mileage, my apologies to you.

There are a lot of factors. With over 120K on two GL1800's I have averaged about 37 per the ODO.

One thing is evident as I have tracked my mileage for quite awhile is that the GL1800 likes warm weather. I'm in Indiana and ride all winter. I will usually see a 5-7 mpg drop in the winter.

I don't care what mine gets.

It's just too much fun to ride to worry about fuel mileage :D

I have noticed that lower mercury makes for higher fuel consumption also. I think it is due to the the rich mixture until warmup.
