Doosan Pro-Tec Portable Compressor Oil Replacement - 5 Gallon

Keep your portable rotary screw compressor running at peak performance with our premium DOOSAN / BOBCAT (formerly Ingersoll Rand) PRO-TEC® 36899706 replacement compressor oil. Formulated as a high-performance ISO 46 synthetic hydrocarbon lubricant, it is engineered to deliver up to 4,000 hours of reliable service under normal operating conditions. Unlike many aftermarket alternatives that rely on basic non-detergent oils, our advanced formulation uses premium synthetic base fluids and a proprietary additive package to help keep compressor internals clean while extending oil life.

While the current OEM PRO-TEC lubricant has transitioned to a partial synthetic formulation with a typical service interval of approximately 2,000 hours, our premium replacement continues to provide the long drain intervals and dependable protection that contractors and rental fleets have come to expect. It is designed to minimize varnish and deposit formation, helping maintain compressor efficiency throughout extended service intervals.

Our PRO-TEC replacement is one of the few pour-over compatible alternatives available, allowing it to be added to compatible systems without a complete lubricant change in many applications. It is recommended for portable rotary screw air compressors operating at pressures up to 300 PSI.

Built for demanding job sites, this high-performance lubricant delivers excellent thermal stability, outstanding oxidation resistance, a low pour point for cold-weather performance, and a high flash point for dependable protection in high-temperature conditions. It also helps protect critical compressor components from corrosion, rust, and wear, extending equipment life while reducing maintenance costs.

Made in the USA.
