Engine is breaking in, of course, but looks good. Need to confirm the shop used 20w50 Yamalube like they told me since the viscosity appears to be lower, possibly 10w40 based on the numbers. When I do the next analysis I'll see how the 10w40 AmsOil holds up to 4,000 to 6,000 miles of use. The lab even suggests I can run 6,000 miles on the Yamalube the shop used before changing, falling inline with what the EU manual recommends for oil change intervals.
I didn't bother with the 600 mile service oil analysis. This is the second oil change with 4700 miles on the bike. I'll probably be doing my oil changes at 5,000 mile intervals (thus the 4,700 mile oil change this time). If it was on the track I'd change it more often, but it's a daily driver (although it's getting about a month off right now).
That's what I thought was weird also, so based on the numbers I'll assume they used 10w40, not 20w50. That makes it a more even comparison between the Yamalube and AmsOil.
Perhaps there's not much to be learned about the engine, but it does help establish a baseline for my bike. Besides, it was more about the oil since I added the TBN test and want to see a comparison between the Yamalube with OEM filter vs. AmsOil with AmsOil filter. Since I plan to change oil every 5,000 miles, that's only about twice a year for me, at the moment. With the money I save by not changing the oil each month, I think I can afford $70 per year for oil analysis.
I've done exactly one oil analysis in my lifetime and that was at 5,000 miles on T6 to see if it was still good. It was still in good shape and it's now my new change interval. Save your money, run a good synthetic, change it every 5k miles and forget about it.
Exactly what the end plan is for me. Just want to be sure I'm running a good synthetic and wanted something to compare it to.
