I like an oil mix to make my own semisynthetic, but many people would get a blowjob from their grandmother before they mixed oils.
A couple of quotes that I found-
"The oil that works well for others might not work well for you, even in the same make/model bike. Amsoil made my bike jump out of 5th and was a bear to find neutral, but other people run it without issue."
"The ZX-14 has a lot of HP and torque and it loves the Rotella T. The ZX-14s run hot normally and the Rotella T has helped the bike run much cooler too. I highly recommend Shell Rotella T synthetic [T5 or T6]."
"That's great advice.....go to a Suzuki Katana forum to get info about a Kawasaki
......just fucking brilliant."
The answer I would expect from someone with nothing new to add, just bashing.
"Until he reached thirty, Randy felt bad about the fact that he was not socially deft. Now he doesn't give a damn. Pretty soon he'll probably start being proud of it." from Neal Stephenson's Cryptonomicon novel (1999).
I've used the T5 and T6 for the last couple years, nothing bad has happened, everything feels the same, bikes run just fine. Done trackdays, everything went well and still is. I have it in my 250, Daytona 675, and my little CRF70, all run just fine. A company like Shell isn't going to put an oil out with a JASO MA certification that is going to murder your bike.
