Big 4 Equivalents Cross-Reference

Approximate functional equivalents from leading global additive houses (Lubrizol, Infineum, Afton Chemical, Chevron Oronite). Chemistry tier, treat rate, and additive synergy may differ — always verify against the supplier TDS before formulation lock-in. Note: zinc-free (ash-free) hydraulic packs are a separate product class for newer pump technologies; this entry covers zinc-type only.
