STIHL High Performance 2-Cycle Engine Oil 6-Pack of 5.2 fl. oz. Bottles

What It Is

This is a 6-pack of STIHL’s High Performance 2-Cycle Engine Oil, pre-measured in 5.2 fl. oz. bottles. It’s designed specifically for STIHL handheld outdoor power equipment—trimmers, blowers, chainsaws, and hedge trimmers—that require a 50:1 fuel-oil mix.

Fitment & Compatibility

Before buying, confirm your equipment uses a two-stroke (2-cycle) engine—not a four-stroke. This oil is intended for STIHL brand engines only, though it can be used with any 2-cycle engine that calls for a 50:1 mix. Check your owner’s manual for the recommended fuel-oil ratio; using this oil in a 40:1 or 32:1 engine will cause poor performance or damage. Each 5.2 oz bottle mixes with 2.5 gallons of unleaded gasoline to achieve the correct 50:1 ratio. Do not use in four-stroke engines, fuel-injected engines, or any equipment requiring a different mix ratio.

Key Things to Know

• Pre-measured convenience: Each bottle is precisely 5.2 oz, so you don’t need to measure—just pour into 2.5 gallons of gas and shake.
• Low smoke & high performance: STIHL’s formulation reduces smoke and carbon buildup compared to generic 2-cycle oils, which is especially helpful for frequent users.
• Mix only what you need: Once mixed, fuel should be used within 30 days. Unused pre-mixed fuel can degrade and cause starting issues.
• Not a substitute for standard oil: This is a high-performance synthetic blend, not a conventional mineral oil. It’s designed for extended engine life but costs more per ounce than generic alternatives.

Should You Buy It

This is the right choice if you own multiple STIHL 2-cycle tools and want a reliable, hassle-free mix that protects your engine over time. It’s ideal for regular users who prioritize engine longevity and convenience over cost. If you only use a single 2-cycle tool occasionally or prefer a cheaper generic oil, you can skip this—but you’ll lose the pre-measured convenience and the low-smoke performance.
