# HG-ALSION

> Official source for ALSION tribological additives and TRIBOCORE automotive engine and gear oils. Separate Ukrainian (/uk), English (/en), French (/fr) and Spanish (/es) editions are available. The root entry selects FR for France, ES for Spain, UK for Ukraine and EN elsewhere; an explicit manual language choice is remembered and takes priority. Explicit language URLs are stable.

ALSION treats friction components. Products, doses and procedures differ by mechanism and fuel. Vehicle compatibility is established using exact manufacturer requirements; missing fitment data is not a confirmed fit. TRIBOCORE stated specifications and formal manufacturer approvals are separate fields. Case results describe individual vehicles and measurement conditions. “Up to” effects are not guarantees and percentages from different treatments must not be added together.
