get 20 weight if you like being a peon to CAFE.
get 30 weight if you like more protection for your engine.
My car currently has 10w30 rp, next oil change goes to 15w40

If you want to push your motor as much as possible without an early engine death then 5w30 or even Xw50 (replace the X with the number of ur choice, like 0, 5, 10, or 15) use straight grade only if ure area is pretty hot all year long.
If you're going to drive like your grandmother, redline like once per month, be part of the C.A.F.E. Supporter then go with 5w20

We are lucky up here in Canada, the local branch of Exxon (Esso) makes an oil with a 100% polyalphaolefin basestock, in 0w30 and 0w40 grades.
Of course, I'll also be going straight to Hell because it's one of themthere newfangled "synthetoids".......

I've used 5w30 from the beginning with my 2004. At first it was because of the serious fuel dilution due to the original tune being over-rich. PCM revisions fixed that, but I stuck with 5w30, since it was the specification for the car in most markets outside of North America.

Heavier oil will protect more because it retain more heat and build a heavier film in the chamber, so yes. In a piston engine if you go too heavy you get sludge, but I don't know about the 8. Either way 5w-30 isn't that heavy.
