First Class engine oil ESPRO GAMA 20W-40 was created for naturally aspirated diesel engines. In order to provide excellent performance in buses, trucks, and LCVs built to Pre-Bharat Stage-I standards, the product is manufactured from paraffinic base stocks and strengthened with carefully chosen additives. The product is especially appropriate for older diesel engines that require less detergency. To enable simple starting even at lower ambient temperatures, ESPRO GAMA 20W-40 oil has been multi-graded to 20W 40 viscometrics. In addition to providing the engine with stronger protection against wear and corrosion, the enhanced additive chemistry also maintains the engine’s cleanliness and trouble-free operation over a wider range of service intervals thanks to its balanced detergency.
