Changed oil in the beast today and realized I screwed up and grabbed 2 gallons of 5-40 and 2 gallons of 15-40. So I now have 8 quarts 5-40 and 7 quarts 15-40 in the engine.

I'm running Rotella T6 synthetic...

Preliminary research on the interwebs make me feel this will be fine but thought I'd throw it out to the motor heads here as well for an opinion..

It's almost a hundred dollars worth of oil so I really hope not to have to drain and replace.
