Just curious to see what you guys use, ive been using 10w30, friend with a 350z said 5w30 is better .

Im in new england to btw.

Which one?

Use 5W30 it's fine year round. Or try 0W30 Castrol synthetic.

yep, 5w or 0w

i've always used 5w30 but recently switched to 10w40 to see if it would alleviate some of my oil consumption symptoms... surprisingly it actually did...
