Amsoil recommends 20w50 in all three holes, with a secondary recommendation of 75W 90 in the tranny. \\;I believe a heavier weight oil is better in the tranny so I am going with that. \\;My indy wrench also recommends a heavier oil in the Tranny.
what they said sounds like a lot of people know about amsoil
 \\;
it is a quality product i just become a san fernando valley distributor
 \\;
good choice all three holes
i would like to add the 1st and the best synthetic amsoil was the 1st to bring out
synthetic oil back in 1972 there product today no one compares mobil v twin is close
but amsoil never breaks down
