This is pump oil made for high-pressure washer pumps. It’s SAE 30 (30W), non-detergent, and sold in a 16-ounce bottle so you can top off the pump fast on the job. Use it only in the pump — not in engines or gearboxes — to keep seals, valves and plungers running smooth and to cut down on wear, rust and foaming. The blend uses premium base oils that resist breakdown and oxidation at high temps, so your pump stays lubed under heavy use and holds its protection between oil changes. It meets API SA performance requirements and has a high flash point, giving predictable, jobsite-ready protection for STIHL RB and other compatible pressure washer pumps.
The bottle is clear amber fluid with a petroleum scent and a viscosity range suited for pressure pump clearances (roughly 46–100 cSt at typical test temps). That viscosity window helps the oil cling where it matters without foaming up under pressure. A single 16-oz bottle is usually enough for a service or top-off on most residential and light commercial pumps, and the narrow-neck bottle makes pouring into the pump filling port quick and clean. This oil is about real protection: it reduces metal-on-metal wear, fights rust, controls foam, and resists oxidation so the oil stays effective longer.
