Hi All,

I'm on an adventure to Newfoundland (blog Chuck's Travels ) and my fuel mileage as fallen from about 50 to 38. My air filter is new, tire pressure good, and at the speeds and load I have, I should be getting about 50 mpg.

The weather has been snotty- lots of fog, rain, mist for the past 2-3 days. On my Ural, I'd dry the air filter & not worry about it. I've not heard of this with a Wee. I was getting a steady 50 ish until my last 2 tanks of gas, both gave me 38, and both were bought in New Brunswick.

Ideas?

I'm in Nova Scotia right now, pointed toward Newfoundland. I'm hesitant to head for the hinterlands if I have a problem developing.

Thanks!

What is the outside temperature like? And the road conditions? Wet weather will not have a drastic effect...I ride every day here in the PNW and noticed no ill effects on my past DL650.

If the temperatures have gone low, that could contribute to your drop...but not that much. Also, bad road conditions could also have some effect.

Most likely, it's bad gas that you recieved in NB. Get out of there and find a good quality place to buy fuel from. See if that helps things.

Thanks for the quick reply- just enough time for me to finish my fish & chips. The roads are nice, not too hilly. Fingers crossed for bad gas.....

Any other symptoms than fuel mileage - Is the bike running and handling like normal? Was anything done to the bike just before this started?

The usual culprits are speed and aerodynamic drag. Are you going faster or adding luggage on top of your helmet?

Just two thoughts;
First, is Canadian gas mixed with higher levels of Ethanol? Have they already switched to the dreaded winter mix in that region?
Second, how long would it take the ECU to learn the new elevation. Nova Scotia is pretty much sea level. Did you just come out of much higher elevations?

The ECM doesn't learn. It has an atmospheric air pressure sensor providing information constantly. Fuel economy is better at higher altitudes.

I'm finally back with internet.

At the next fill up (in Nova Scotia) I sprang for 89 octane. My mileage is back to normal. I'll stick with the higher octane until I'm home. I'm hoping it was just some evil blend of gas in NB.

I'm riding at what I would consider normal speeds, with a load I have carried many times, at roughly the same elevations as home. Scott oiler is working fine- so I was worried. Things that change for no reason are usually not good.

I'm now in Newfoundland, hoping the rain stops. Next stop- L'Anse aux Meadows- the viking site!
