Well, its hotter than I expected.
I ran my 2GM20
today with the following results.
Ambient air temperature 13C.
warmed up and the ran at 3,000 RPM
(in gear) for 1 hour.
temperature measured where it exits the head
Oil temperature measured at the oil filter (and at the front of the sump) was 70C.
Thermometer was a Fluke IR unit.
It took quite awhile for the oil
temperature to stabilise - say around 30 to 40 minutes. I wonder if it would be a few degrees higher with higher ambient temperatures but it will be awhile before I can test this
, its autumn here...
