Superior performance – the first non-synthetic extended drain and warranty gear oil in the market.

Long equipment life – unique borate additive technology, formulated with ISOSYN® technology, provides excellent overall wear protection and enhanced equipment life.

Improved fuel economy – has better friction control resulting in lower operating temperatures and less energy used compared to conventional drain lubricants. The less an engine has to work its drive transmission and differential, the more fuel it saves.

Unsurpassed wear protection – offers unsurpassed wear protection, excellent oxidation stability, outstanding rust and corrosion prevention. The borate additive system provides a lubricating film, which does not corrode metal surfaces, unlike many other sulphur-based gear lubricants.

Low operating temperatures – works effectively across a wide range of applications providing reduced operating temperatures, extended lubricant and equipment life.

Fully compatible – compatible with synthetic and mineral-based gear oils for easy top up. Delo® Gear Lubricant ESI is also fully compatible with all commonly used automotive seals.

Automotive differentials operating in severe (service) conditions.

Heavy duty transmissions where the manufacturer recommends the use of API GL-5 or MT-1 gear lubricants.

In-service top up of limited slip differentials.
