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
