The second set of numbers below is from the previous test with Amsoil 10-40
done with 4000mi on oil.
With 3000 mi on RotellaT viscosity (11.5) held to upper 30W, it looks like it
would work as long as one wants to change oil every 3K. No oil was added.
Note, that this is a machine that BRP claims only needs oil changed every 9000+ miles!
I'm running Motul 7100 for the next test and will test it at 4000 mi.
Lab saw no unusual wear numbers but gave the viscosity a Yellow flag.
