i own an acura rsx and, i use synthetic by choice for extra protection. this makes sense because it is a high-revving, high performance engine.
my dad just bought a 2003 2.3L ford ranger truck. why does the manual say only to use synthetic oil? the ford ranger 4.0L requires regular oil while my dad's smaller 2.3L requires synthetic. can anyone explain this?
