Give your high-performance equipment the ultimate protection with STIHL HP Ultra Oil. This fully synthetic 2-cycle engine oil is specifically engineered for professional-grade chainsaws and power tools that operate under demanding conditions. With outstanding engine cleaning characteristics and "ultra" lubricating qualities, it far exceeds the performance of standard two-cycle oils to keep your engine running at peak efficiency.
In addition to its superior protection, STIHL HP Ultra is an environmentally conscious choice. This highly biodegradable oil degrades by 80% in just 21 days, reducing its impact on the soil and ecosystem. We are so confident in the performance of this oil that STIHL will double your limited warranty when you purchase it alongside a new STIHL gasoline-powered tool.
Warranty Tip: Double your limited warranty protection by purchasing a six-pack of HP Ultra Oil or one gallon of MotoMix® fuel at the time of your STIHL product purchase (personal, non-income producing use only).
