reported Oil pressure anomalies

[Reflected]

Warming up the Mossie made me find some oddities:

On a winter mission below 0 C the oil pressure drops faster than on a mission at 10 C. Shouldn't it be the other way around? 

Also, the oil dilution buttons seem to have no effect whatsoever?

With regards to the oil dilution I have also noted after not flying for a while that the oil pressure on start up maxes out like the spit. I've tried the oil dilution to try and sort this but not quite sure how/if it worked? The left engine pressure seemed to drop a little but right didn't drop at all.
