Hi, I am a new owner of a '46 3/4 ton with a stock 216 and 4 speed trans. I have other vintage vehicles but I'm new to the chevy in line six. In other cars I use Valvoline VR-1 racing Oil 10W30. I like it for the elevated level of zinc to protect the engine. Yes, I know that discussing engine oil can be polarizing but I'd like to hear what you guys think is the optimum engine oil for this old 216. Also interested in what what you recommend for transmission and differential lube. Thanks!
