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.

in an engine thats designed to burn oil, using a higher weight oil isnt going to prevent oil burning like in a conventional 4 stroke where a thicker weight will prevent seepage pass the rings.
but again, if ur using a higher weight oil to prevent seepage pass the rings, ur just masking a problem that is there.
