I'm not very informed when it comes to deeper internal engine knowledge . So I want opinions from the pros who do deep older engine repair. What grade and type of oil and manufacturer do you use in your flatheads ? Why do you prefer it what gains or advantages to what you run . I know alot of younger guys on here could use this info also . As always Thanks for the help and opinions are valued as always . Before anybody chimes in I searched if there is a thread on this it must have an odd title I could'nt find anything.
