Forget the standard lubrication equation—STIHL HP Ultra isn’t merely an oil; it’s an engineering commitment to the life of your engine’s internal components. While many oils aim to prevent failure, HP Ultra is formulated as an ash-free, fully synthetic ester that aims for perfection. After hundreds of hours under brutal, full-load conditions, a piston running on HP Ultra remains so clean it looks almost brand new. This relentless commitment to purity means zero carbon buildup on the piston crown, in the exhaust port, or on spark plugs. This isn’t just a claim of “better protection”; it’s the quiet promise that your high-performance STIHL machinery will maintain its maximum designed power, responsiveness, and compression for years longer than you thought possible. Choose Ultra, and invest in an engine that never stops running like it’s fresh out of the box.
