• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

Valvoline 20-50 MC convential oil in a 2015 St998

Am i ok to put this in for the summer?

I run against the grain ( somewhat ) I normally use this Formula ….. 4 qts. 5W-40 FULL synthetic and one qt. 20w-50 also FULL synthetic … I do this to lessen the viscosity loos ….. jmho .. …. Mike :ohyea:
 
I have been using 10W-40 Valvoline Motorcycle oil. I would not use anything heavier and it would have to be motorcycle oil for wet clutch. It is FULL synthetic oil.

Is there a particular reason that you want to use that specific oil? The specified oil is readily available. Just curious

Always a good, No:cus: recommendation. Unless one has PhDs in petroleum and mechanical engineering it's always wise to follow the instructions of those engineers that designed and manufactured the vehicles.
