Less time to warm-up and thinner oil I expect, mine's doing the same.

What should the oil pressure be? Mine is only 40 max even when cold. Is this O.K.?

theres a good question... just scourd the haynes and engine manuals and cant find an answer... be good to know this one

Hotter weather = lower air density = less fuel used due to lower air flow?

 

[Oxymoron]

On a short commuter run the engine will reeach operating temp quicker and the oil will be thinner quicker.
But hot weather reduces your engine power as well.
You want a nice cool day for maximum HP!!!!!!!!!!

Stock oil pressure guage is rubbish, so many stories of them reading 0 pressure. I never look at mine tbh cant be arsed, but will wire up my aftermarket one soon and have a look what im getting then.
