Regarding your question: "polyalphaolefins like Mobil 1 ... and poly-esters". Tomorrow please as it is approaching 11 PM.
The easy part:
Regarding the use of AMSOIL synthetic motor oils in brand new or rebuilt engines, it is recommended to operate the engine up to its first normal drain interval with a petroleum motor oil. There are a couple primary reasons for this recommendation:
New engines or engine components generate high wear metals to begin with and generally contain debris from machining and assembly. It is more beneficial to allow these wear metals to collect in an inexpensive motor oil than to circulate throughout the crankcase for extended periods in a synthetic motor oil. By operating the vehicle to its first drain interval with a petroleum oil, these wear metals and manufacturing debris collect in the oil and are then flushed out of the crankcase when drained. This allows for a much cleaner operating environment for the synthetic lubricant.
Within the first miles of operation any defects in the assembly or workmanship of the engine components may be corrected before installing the more expensive synthetic motor oil.
Occasionally, rebuilt engines may have re-machined components or materials which can sometimes be mismatched. These problems will develop in a fairly short period of time. If excessive oil consumption or any other problem is noted, this should be corrected prior to changing to AMSOIL synthetic Oil.
For racing applications a synthetic motor oil can be installed immediately . These engines are frequently disassembled and rebuilt under more exacting conditions and require the improved wear protection of a synthetic motor oil. Extended drains are rare due to contaminants such as fuel dilution and dirt, and oil analysis is recommended to determine the serviceability of the lubricant.
