i'm searching the web for B3 vs B4 information, read all kind of opinions, saying that B3 is much tougher oil than B4, which mean it (B3) would protect better against wear.(in C3 oil's)
so i'm a bit confuse, isn't B4 should be more advance than B3?
hope you guys can spare few minutes, educate me.
thanks in advance!
