WINIRON SAE 80W-90 API GL-4 Gear Oil — 1 L

WINIRON SAE 80W-90 API GL-4 is an automotive transmission oil (Transmission Oil) formulated with Korean quality standards (Korean Quality and Technology) and proprietary Anti-Wear Technology.

According to the packaging labels, the product features an all-season SAE 80W-90 viscosity grade and meets the API GL-4 specification. This standard is optimal for use in manual transmissions (MT) equipped with non-ferrous metal synchronizers, as the GL-4 additive package provides reliable gear protection without aggressive effects on the synchronizers. The 80W-90 viscosity guarantees a robust lubricating film at operating temperatures and helps reduce transmission noise.

The base oil type, exact physicochemical properties, manufacturer details, and official OEM approvals require confirmation via the product's Technical Data Sheet (TDS).

Package volume — 1 liter.

Recommended for manual transmissions (MT), transfer cases, and steering mechanisms of passenger cars and commercial vehicles where the manufacturer requires an SAE 80W-90 viscosity and API GL-4 specification gear oil.

Always consult the vehicle or equipment owner's manual before use. It is not recommended for use in hypoid drive axles requiring API GL-5 oils, as GL-4 does not possess sufficient extreme-pressure properties for ultra-high loads.
