don't want to use synthetics for breakin anyhow. There are a lot of

Why not- cheap & easy.

Run Castrol 20-50 in all my British street engines in summer. 10-30 or
20-50 in the Japaneese stuff, seasonally. Something reasonable in
my Ford truck, and straight 30 Wt in my '39 Ford tractor. The
30 wt. is a candidate for break-in. Less additives.
Just to throw in my $0.02, upon rebuilding my Spit 1500 engine I was told by a
very
reputable place to use straight 30W for break-in: racing oil. It worked fine.
Also, change the oil and filter after the first 100 miles.
