My whole thing is that i feel like 0w-30 is way to thin for high performance engine while 5w-40 seems a bit too heavy for normal use. Different story for track of course. Pennzoil Gas oil technology just seems very attractive  |
Interesting, I didnt know Castrol still made an LL-01 5w30. Guess you can find anything on Amazon!
I wouldnt worry about the viscosity grade of any LL-01 oil as they will all have similar characteristics even though the viscosity is different. There really wont be much of a difference between a 30wt and 40wt LL-01 oil. Just choose whatever is most convenient or tickles your fancy.
