Oh god... dude. This always sparks the dumbest debates. to kill it in advance. By page 2, guys will have viscosity charts, from Bob the oil guy.
My personal preference in order is. Redline and Royal Purp tied for first
Castrol edge 5w-30 is my budget choice. But the first two run so well,I would just shell out the extra cash.
I don't like the contracted nissan dealer synthetic in our cars but others have charts that say different. Lol. I'm basing mine off taking my car over 140mph. Not charts. Hope that helps Lol.
There are thousands of threads on this though. You could have done a search.
