Then I change nothing, because I trust Crimson on everything. I guess I'll go ahead and switch to Rotella for the same reason at some point.
I hate oil and tire threads,
Your decisions are all up to you,
I use Castrol dino oil, and change it @ 4-5k intervals, with a new filters..
All in all, every owner needs to build a database, subject to their findings using whatever for a long enough period of time, to find them viable...
I don't make a decision on "group" recomendations, I've been doing motorcycle repair and service for 40+ years, my choices are based on those years, and any findings I had making changes... I've found that using something another person says is gold, was only gold for them, and if they sold off the machine after 3 or 4 years, they could have used olive oil in the machine for that basis...
Now I'm gonna try the Castrol synthetic one time, next week, and I will run it for 8k miles, because it SHOULD be good for that many,
People draining synth oils every 3-4 k are just tossing money away..
Oil threads suck bigtime.
