My Mobil 1 15/50 Oil Numbers
Just got my oil analysis back. OK, I know, another freakin' oil thread. Well pop the cap and grab the popcorn and have at it anyway.

Very interesting and what do they charge for the lab work? Any other suggestions that they offered? I noticed a 1/2 qt of make up oil. Was that normal for your machine?

I changed out my filter every 2500 miles.

Looks good me to. The motor beat it into a 40wt after 6k miles which is pretty normal for motorcycles. I use 15w-50 but change it every 3k miles because of the viscosity loss. The mobil 20w-50 would have stayed in grade longer but wear is the bottomline and your wear looks good (lack of wear).
