The oil gets thinner as it gets hotter and so you see less oil pressure.  How 
thin it gets at a given temperature is what the SAE grading indicates.  How 
thick it gets at a cold temperature is also what the SAE grading indicates.

A 15/50W oil doesn't thin out as much as as 15/40W.  If you fit an oil 
temperature gauge to your Sprite you can see the pressure drop on the 
pressure gauge while the temperature goes up on the temperature gauge - until 
both stabilise.  The only thing that really moves the temperature gauge is if 
you start to use a lot of rpm over 6,000 for more than about 5 minutes - even 
with an oil cooler.  But even so the temperatures seen in the sump (where I 
have the sender fitted) are not even close to that of a Turbocharger centre 
bearing and oil gallary which is why STP is ok though with a Synthetic like 
Mobil One you really don't need it.
