The Stihl HP Ultra Synthetic Oil (2.6 oz) is a high-performance 2-cycle engine oil formulated for demanding professional use. Pre-measured for a 50:1 fuel-to-oil ratio, this size is designed to mix perfectly with 1 gallon of gasoline, making it a no-guess solution for consistent, reliable fuel blends. This oil is engineered with a fully synthetic base and exceptional lubrication properties, reducing friction and wear on critical engine components. The result is longer engine life, improved efficiency, and dependable performance in high-temperature, heavy-duty applications.
Stihl HP Ultra also features low ash additives to keep combustion chambers, pistons, and exhaust systems cleaner. This minimizes carbon deposits, reduces spark plug fouling, and maintains consistent power output over time. A key benefit of this oil is its biodegradability—over 80% of the oil degrades within 21 days. That makes it safer for the environment without compromising performance. It’s ideal for professionals working in forestry, landscaping, and municipal settings where both reliability and responsibility matter.
