what about worrying about viscosity being too thin that causes oil pressure loss and losing the capability of keeping the conrod and main bearings in full-float mode via lubrication?
using 5w20 on 5w30 engine, how bad can it get in reality?

pump still works with rotation of the engine purely mechanically. If you put water through the pump, it's just not thick enough to maintain the oil pressure. I'm sorry I don't really know how to put it in words mate.

ive no time to read that link yet.. but, cant be too thcik cant be too thin.
too thick, cant flow through the channels and lubricate the main and conrod bearings. Yes, these are full float bearings. Exact viscosity gives you good pressure and flow, but if it's too thin... hailat. |
