I have personally used Amsoil products for over 10 years, in nearly every aspect of racing and hard street riding. I firmly endorse their products.
I recommend the 10w-40 or 20w-50 Synthetic High Performance Motor Oil (available by the gallon)
(NOT the Series 2000 which is formulated for wet clutches), and the Series 2000 75w-90 Gear oil
for your trans and final drive.
The SMF134 oil filter is recommended for both the California based V11 and
the V11 Sport models. Dan Doran - AMSOIL Filtration Department
