| Subject: | Re: Super-cool oil temp |
I think closing the gill shutters on the ground (at any time) but especially to
increase oil temperature is bad advice.
With no airflow over the cylinders the CHT probe is not necessarily telling you
the hottest temperature. With stagnant air there could be undected hotspots creating
all sorts of ugly things to be happening to the cylinders.
Cooking cylinders to get the oil to warm up a bit quicker could be a pyrrhic victory!
Oil lubricates despite it's temperature - its the high pressure that is the problem
and usually only through the oil cooler as the cooling vanes in these are
the weakest link with regards to excess pressure. Hoses in correct condition
and the engine itself can handle much higher pressures than redline. Try using
multi-grade, clicking oil pump PRV down a notch.
With single weight oils temperature is just a good proxy for pressure.
Stand to be corrected on any of this.
