I'm a new guy with probably an old question. I was curious what oil other bolters are running, I have been running castrol 5w30 with BG's RF-7 additive in my 250 six. Is this a good combination or am I missing something vitally important? Just concerned about what I hear with modern oils not having friction reducers in them that older engines need.
Any help is appreciated
