What's the hot ticket on engine oil?

I would think most guys here just want the best and don’t worry too much about cost when it comes to oil

The 1968 service manual says to run 20w50 so that is what I run.

I run Royal Purple HPS 20w50. $50 +/- for oil and a filter is no big deal. That's less than it costs to fill the tank once a week. If I wanted to save money on gas and oil and ****, I'd drive a ******* Geo or Yugo!

You make the call.
