We use Valvoline 20W-50 Part #VV851 which is available at just about any
auto parts store. You have to ask for it by part number only and it is
kept behind the counter because it is not "street legal" due to the ZZDP
and other friction modifiers used in the oil. Have had no problems with
it and we use it in a number of antique cars varying from 45 to 75 years
old.

In the world of aviation, we break in an engine with straight mineral
oil
for the first few changes (10 & 25 hours) then switch to an ashless
dispersant (additive) oil or semi-synthetic. The FAA subscribes to the
theory that
straight synthetic oil will run off the cylinders and other parts,
leaving
them open to rust and corrosion. Most aircraft engines, like most Tiger
engines, do not see everyday use.

Have you already done a break in run on the engine? I would use
10W30 not 20W50 plus a bottle of break in oil that has all the high
pressure
additives for the break in run unless you have a roller cam which does
not
need the additives. I would continue to run 10W30 or 10W40 as regular
oil.
Some of the oils have more of the additive but I'm not sure off hand
which
ones.

Subject: [Tigers] Best Dino Oil for 260/289/302?
I am trying to figure out the best choice of dino oil for the 289
engine.
Because the engine is freshly rebuilt and needs to be run in, I don't
want
to use synthetic (too slippery). What grade oil are you all using,
20W50?
