So my block is almost done being built and I see a lot of different information flowing around. I get free Castrol 5w30 full synthetic at work and I’ve always used that for my oil changes. My question is have any of you guys used the redline break in oil additive? If so any luck with it? If not then what have you guys tried and what’s been your luck?
I was thinking amsoil or liqui moly.
Motul is also on the list but idk which motul tho, I’m not really a fan of royal purple and I’ve never really used redline before so any info is helpfull
