2018 GoldWing. Mobil1 0W40 fs. 3800 miles on oil
Honda specs 30 weight. As typical with shared sump bikes I suspect oil sheared to a 30 wt. within about the first 500 miles or so. Starts out at a mid-low 40wt. Sheared to a mid-low 30.

I didn't know M1 0w40 would be suitable for this application.
Do you have a link to the version you are running?
Considering it's suitable for a shared-sump, I'd consider running it in my VFR.
 
Wow, that 100ºc KV was torn up at 10.22 cSt. I'd stick with a 10W-anything for this monster. I think Honda's recommendation is a pretty spot-on grade for this bike.
 
Is there a fuel dilution value there somewhere? If so, what ASTM method was used to determine the value?

Without that no one can determine if a viscosity deviation is due to mechanical shear of the VM or from dilution. Both have different causes and different potential mitigation.
 
This Mobil 1 FS 0w-40 was a good choice. As you mentioned they recommend a 10w-30 but the Jaso T 903 their basing it on is a bit slim on viscosity. It allows 2.9 HTHS as the minimum & you used a 3.5 HTHS minimum oil here. Jaso spec allows 30, 40, & 50 grade oils to be used. Your results on this sample look good in any case but don't have much to compare it to either. Stay visible out there

Here's some other options from thin to thick. :)

It’s just 0W40 fs from Walmart. Not JASO rated if that’s what you are referring to. I have close to 500,000 miles on shared sump bikes and have never used a “motorcycle oil”. I only ran the sample to see how the viscosity held up.

Didn’t run fuel. I’m sure it’s from mechanical shear. Bike is almost NEVER started unless I’m going to ride it minimum 50-100 miles. Have run analysis on 4 other bikes with different oils including “motorcycle oils” and all shear the Viii’s within the. first few hundred miles.

Never have used “motorcycle oil”, but if you look at other analysis in this section you will find Honda oil shears to a mid- low 20, and is not a very impressive product in both the Dino and synthetic blend.

Also with a measurement of fuel dilution?
