Thanks man,

Yeah, it is nice for us new owners to learn from the more technical blokes on this forum.

To draw from & add to Honda's and 333's discussions:

I'm trying to focus on the requisite oil properties for our engines rather than brand:

For flat tappet/ sacrificial boundary protection:
Zinc > 1100ppm but < 1500ppm per LN Engineering
Phos > 1000ppm

For cold flow & hot hydrodynamic bearing protection:
Pour point < -30F
Viscosity at 100°C (212°F) ASTM D445 > 13 mm²/s

For extended (>3,000 mile) OCI drains:
Total Base Number > 10

More than a half dozen oils fit these parameters.. some synth and some dino.
If there's an oil property that I should add, please suggest.
Ultimately, my aim is to build an online searchable database of all solutions 944...
parts, fluids, repairs, noises, failures, etc..
