I run 20W50 Mobil 1 synthetic in my Spitfire. I have not had any problems,
or leaks. I have noticed, though, the engine does run a bit cooler. If you
are using real rubber (not neoprene) in any seals, though, I would not
suggest using synthetic, as I have heard that organic helps keep the seals
from drying out and synthetic does not.
This is from my experience, as I have put ~10K miles on my Spitfire while
using Mobil 1. I have tried lighter weight oils, but it seems to run better
with 20W50.
