GS Fuel Mileage

[MarkLawson]

My wife & I road in the mountains of north Georgia after church Easter Sunday. Because of some work I am doing on my RT, I was on our GL1800A Goldwing while Mary Lou road her '08 GS. This was her first time in the mountains and the twisty roads while in the front seat. We took the day nice & easy & she did great.

On the way back, we stopped for gas. I got an amazing 43 mpg on my Goldwing, some 10 mpg higher than normal. Over the same miles, she only got 20.1 mpg on her GS, some 10 mpg less than the previous tank.

I really was amazed at the difference. If the miles were that easy on the Goldwing, why was it just the opposite on the GS? :dontknow:

Too much time in the incorrect gear on the :spyder:? :dontknow:

I would think the wing would be more forgiving with that flat 6. Just a guess....

It can be difficult to get a go MPG calculation from just 1 fill-up. Just a small amount of difference in fuel level in the tank can make a lot of difference.

It takes at least 3 or 4 fill-ups averaged to really know what MPG your getting.

How you ride can make a lot of difference as well even over the same piece of ground going the same (average) speed.

Regarding averages, I agree.

One fillup can be a data point, however. There are different variables as you imply. The more you reduce/eliminate those variables, the more accurate your data is. Alternatively, the more data points you have, the more believable your data is...at least, should be.

You have to make sure your filling the tank with the same amount of fuel every time. There's something with the Spyders tank that makes it hard to do. A couple of tents of a Gal. + or - will trow your calculations way of.

Exactly. And I'm not saying the MPG's given are not accurate. All I'm saying is that 1 MPG calculation on anything with a tank as small as the Spyder or Goldwing has a high probability of being off by quite a bit.

The Goldwing was sucking gas out of the Spyder while you weren't looking?:dontknow:

They do share a garage together...
