Just a couple of weeks ago, I heard an oil engineer from Spectro do a
tech on this at a bike rally. Afterwards, I asked him what I should run
in old British cars with flat tappet cams if I did not want to spend $12
a quart for specialty motorcycle synthetics like his product. He said
if I wanted to stick with dyno oil to choose any of the major diesel
truck oils for a good dose of ZDDP. Stuff like Delo or Rotella-T.
And what about the idea somebody threw out a few weeks ago about dosing
our old 20-50 Castrol GTX with bottle of STP? Any validity to that?
Necessity should be the mother of invention!

Hi Ed,
The article is good, but there have been some changes in formulation
since
article #3. Industry has reformulated those reccommended oils so little
of
the oils are available with the ZDDP at levels needed for our engines
and
the type of oil needed. Yes, Oil is not oil for lubrication purposes on
engines.
For the break in oils, it's now suggested that any HD30 weight with the
Crane Super Lube added to it. At the moment, Crane is backordered on
the
additive. After break in there are but 3 oils that are suitable to use
on
our flat tappet engines.
Valvoline VR-1 20-50
Castrol Syntec 20-50 Look for the notation on the bottle back, suitable
for
classic cars.
Red Line 10-40
That's about it for now on the oils suitable for our newer old engines.
I guess the days of whatever is on sale is OK for our cars is gone
forever.
Later, Paul A
