I talked to at least a dozen oil experts, some who have Ferrary
vehicles for a long time and don't follow factory suggestions. Most
have convinced me that 0w30 synthetic is the best motor oil for my
application. The best advice I got was from a man who owns a late 80s
non-diesel mercedes with almost 1 million kilometers without any
repairs. His suggestion is to not rev the engine beyond 4000RPM any
more. Try to accelerate as slowly as possible without interfeering
with the traffic behind. Use high quality 0w30 or 5w30 synthetic.
Change it at 10,000 mile (16,000Km) intervals including the oil
filter. Before filling with fresh synthetic oil, clean the engine with
cheapest fresh oil (doesn't need to be synthetic) for approximately 15
minutes or longer if in winter. NEVER use petroleum based engine
flushes. Flush the transmission on every change interval that I follow
(for me it's every 50,000KM) i.e. drain, fill, drive 3 times. Make
sure the tires are always properly inflated i.e. check every week. The
idea of the latter suggestions is to reduce the load on the engine as
much as possible. Lastly, take a sample of the oil during the drain
and send to lab for analysis. He did this every 50,000km. I've never
done it, but I will do this at my next oil change. I am kind of
curious as to what the report will show. Some people I talked were
truckers. Alot of them use Amsoil. Some are obsessed with oil. They
have onboard oil centrifuge-like gadgets that act as oil refineries
that allow for driving up to 100,000Km before replacing the oil.

Thank you all for your suggestions.
