Ok, all good answers and info...so next question....if I switch to 20/50 because of Oklahoma summers.....(over a hundred) is there a possibility of it hurting the Vmax? Will it add a couple pounds of pressure at hot idle? Will it offer more protection? Or am I better off doing Seans upgraded oil system and the like.

:ummm:

Yamaha Recommends using 15W40 (or YamaLube 20W40) for temps up to 120 F.
You probably wouldn't have any issues with 20W50.
I used 15W40 for years in my Vmax when I lived in Raleigh, NC and summer temps regularly hit 95 - 100 F without any problems.
The Attached picture is from the Owners manual.

All I run in Toxic is 20/50 Castrol. Have had very good luck and it seems to maintain its viscosity across all the temperature ranges I ride in.

I use the mobil 1 20w50 without issue.

You could always blend your own using the same brand/type 2Qts 10w40 and 2qts 20w50 = 4 qts of 15w45

Went to napa today for some rotella t 15w-40. On the way out I saw napa 15w-40 on sale for ten bucks a gallon. I kept my rotella, but I thought that was a good deal if anyones interested.

I've seen good reviews on the napa diesel oil. I just started putting it in some dirtbikes for a trial run

I've always used Rotella T 5w40 in my turbo Subaru. Good stuff. Can anyone tell me if they have a synthetic 15w40?

No, The Shell Rotella T 15W0 is Regular Oil but it is JASO MA Complient (or Motorcycle Use).

They make a Shell Rotella T6 5w40 Synthetic that's also JASO MA Compliant.
Personally I use the Regular Rotella T 15W40 and have been for over 10years now without any issues.
