Is it possible to run 20W50 oil in our cars without damaging the engine?
EVERYBODY I have talked to with a G2 said the stock B18A burns at least a bit of oil. That’s life. But if I’m allowed to run 20W50 that could greatly reduce the engine’s tendancy to burn it off at higher RPMS where my motor lives 
If you stay above 5k rpm at ALL times AND live in a hot climate, then I can see the need for it. However, you ain’t going to damage the engine by adding a thicker oil, you’re going to damage the engine by staying in the upper rpm band all the time!
Here are just my thoughts (which I can be completely wrong):
Viscosity Index (VI) is one of the key (if not, most valuable) attribute of an oil. VI determines how well the oil lubricates the important parts like bearings, journals, etc. The higher the VI, the better. And generally, the thinner the oil, the higher the VI.
Make any sense?

Yup, MOBIL 1 looks somewhat like water!
