S-OIL 7 GEAR TO-4 is high performance lubricants which is formulated with very stable base oil and advanced additive technology for reliable operation of heavy-duty equipment. It can be used when manufacturer recommends a lubricant meeting the Caterpillar TO-4, Allison C-4, Komatsu and other off-highway equipment requirement.

Heavy-duty off-highway equipment’s powershift, final drive, wet brake and hydraulic system

Heavy-duty diesel engine oil requiring API CF/CF-2

Other applications where manufacturers recommends a fluid meeting Caterpillar TO-4/TO-4M, Allison C4 specification

Excellent low temperature fluidity
It provides smooth start-up performance and hardware protection in cold condition

Reduced maintenance cost
Maximized oil life from very good oxidation stability, resistance of sludge, varnish, deposit formation 

Latest corrosion inhibitor provides reliable protection of critical part in heavy-duty equipment

Reliable wear protection performance
It doesn’t contain viscosity index improver made from polymer. So It provides consistent film thickness

Proven anti-wear performance provides extreme protection characteristics beyond Caterpillar TO-4 requirement

Operational convenience
It provides optimized friction properties, so operator can feel comfortable and reliable
