<VV> Fully broken in and ready for synthetic oil

A repeat of a year old post for our friends who haven't been paying 
attention --  check out the links and READ!

Periodically, some Corvair or Porsche guy asks, and here is the latest
version of my reply -- some websites may be outdated or no longer active. 
Brand and /or type is unimportant -- service classification is.

Oil was big stuff a couple years ago when nobody knew much about what
was happening, but now, lots of people have done/are doing the research
and there are numerous web sites, each with their own opinion. Also most
of the manufacturers address the issue on the corporate web sites, but
can you trust them to tell the corporate secrets?

Perhaps the oldest one is here, frequently updated, by a guy that sells
Nickisil cylinder barrels  --

 From the 356 Porsche folks, who have engines a lot like the Corvair --

Richard Widman is an oil importer in South America restoring and old
1960 Corvair -- laws down there prevent him from buying a nice one in
the states and importing it -- has to work with what is already there --

then there are these folks in addition to whatever shows up when you
Google for Oil Zinc --

And, once you get past the Amsoil faldaral, there is an interesting recent
thread on the Corvair Center Phorum and, one can always search the VV
archives -- nothing against the product, just the Amsoil marketing 
program ...

Was at a shop where they build very high end (read expensive) high 
performance motors the other day, a place where they break-in their  
engines on a dyno, and they indicate they have had very good results, so 
far, with this Lubeatech stuff, especially the break-in oil:

Apparently the oils, either dino or synthetic, you want to avoid for the
older "flat tappet" engine designs have an ILSAC GF-4 rating in the fine
print on the back of the can, and they say "ENERGY CONSERVING"
in the little SAE circle logo identifying the oil rating.

Godspeed!
