Just wondering,
Does anyone run 20w 50 weight oil continuously in your GL1500?
And what benefit or bad effect if any did you notice.
Not interested in brand just weight. I currently and always have
run 10w 40 since 2004.

Re: 10w40 or 20w 50
Most of oil weight differences are due to the smaller size of crankshaft oil passages.
My F-150 crank (for example) has smaller passages.. Ford requires 5W-20.
The other clearances are the same as older design engines.
I'd guess it's an effort to improve oiling toward the other (upper) areas of the engine.
This is in reference to improving mpg with less oil going to the bottom end, windage, and the improved
quality of todays oil.
"Bob the Oil Guy's" website is interesting btw.
I'd suggest using whatever weight oil is recommended by Honda. pc
