KATANA MakuriGEOLA 40Plus – Low SAPS engine oil, specially designed for use in heavy duty stationary gas engines fueled by natural, associated or biogas (Caterpillar, Jenbacher, Perkins, Wartsila, Deutz, etc.). Suitable for high drain intervals (up to 2900 h according to manufacturer's recommendations).
KATANA Makuri GEO LA 40 Plus is produced on high viscosity index hydrocracked semi-synthetic base oils (Group II) and low ash additive package. Oil has good detergent-dispersant properties, which ensures high engine cleanliness, and thanks to the low content of sulfated ash, sulfur and phosphorus prevents surface ignition and the formation of ash deposits on pistons, valves and combustion chamber. It provides excellent protection against oxidation, corrosion and nitration, protects the engine against wear.
