I'm not gonna go through this whole thread, but what are people's opinions on 5w20 weight oil?

I know this is what is recommended and used by manufacturers these days, for many vehicles. but personally, I don't believe in using such a low viscosity oil. I know it is more efficient (less friction for the engine components allowing better fuel consumption), but I feel that a 20 weight simply won't provide the type of lubricating protection that a 30 weight (or higher) would.

for example, the RX-8 is supposed to use 5w20 as per Mazda's manual. I'm sure the Renesis motor has mad many advances compared to the RX-7's 13b(t) engines of yester year, but it's still a rotary engine. an oil burning, gasoline guzzling rotary... using a low viscosity oil like 5w20 isn't going to help in the oil burning department.

discussions? can someone please fill me in on what I'm missing on using 5w20 oil.
