I've owned alot of Amcs with the inline six.They always seem to prefer thicker oil.So now that I'm on the synthetic oil bandwagon,is Castrol edge 5w50 a good choice?
I Just got a nice 82 Eagle with 200000 on The clock.Its a auto and 258 carbed six.I'm wondering if I should use atf+4 in the trans and transfer case,and Delo 80w90 in the rear?
