I thought I'd share this so that others could try it and see if they run quieter also. I'm interested in hearing about your experience with oil. I think I'm sold on the V Twin Synthetics.

I too ran Mobile 1 v-twin 20-50 my last and currant duration. Total miles at last change 9000.
I also sent a sample to blackstone lab far a complete analysis including tbn. My oil had 4500 miles. The last 900 miles of that 4500 was a trip to the dragon. 90% of my miles are in 5th gear. 50% of those miles are @ 75mph interstate.
The lab told me to "check back in 5500 miles" before I change.
TBN was 6.1 and should be greater than 1.0
Aluminum was a little high at 27 which should have been below 7 ppm.
Iron 18, should have been below 15 ppm.
Silicon 15 should have been below 10 ppm. I like that.
Zinc 1488 which is great. They wanted to see at least 1363 ppm. Zinc helps prevent wear, but kills catalytic converters. I like high zinc oils. Most racing oils have high zinc levels.
Hi-Vis: This is a young engine yet, so we're not worried about the elevated aluminum, iron, and silicon
readings. Chances are good the metals are due to wear-in of new parts and the silicon is from sealers used
when your engine was assembled. It can take a few oil changes before a brand new engine starts making
average wear, so we'll look for improvements next time. Averages are based on 1,500 miles. Since you're
already running longer, your metals may not match average, but they should be close. The TBN is fine at
6.1 since 1.0 is low. Check back in 5,500 miles.
Guys, I have worked in a lab 33 years. I am certified to do my lab work and I respect the work of other labs. I beg others to do an oil analysis. Especially when some members are reporting top end failures @ 30k miles.
