STIHL 0781 313 8010 6.4 Ounce High Performance Ultra 2 Cycle Engine Oil, 6 Pack

What It Is

This is a 6-pack of STIHL 6.4-ounce bottles of High Performance Ultra 2-Cycle Engine Oil (part #0781 313 8010), pre-measured for a single fuel mix. It’s designed for STIHL handheld 2-cycle equipment—chainsaws, trimmers, blowers, hedge trimmers, and brushcutters—not for lawn mowers (which are typically 4-cycle).

Fitment & Compatibility

• Not for lawn mowers: This oil is for 2-cycle engines only. Most walk-behind, riding, or zero-turn mowers use 4-cycle engines and require separate engine oil, not fuel mix.
• Fuel ratio: Mixes at 50:1 (2.6 ounces per gallon of unleaded gasoline). Each 6.4-oz bottle treats 2.5 gallons of fuel.
• OEM vs aftermarket: This is STIHL brand oil, engineered for their engines. It meets ISO-L-EGD and JASO FD standards, so it’s suitable for any 2-cycle equipment requiring those specs (e.g., Echo, Husqvarna, Shindaiwa), but always verify your engine’s required mix ratio first.
• What to check: Confirm your equipment’s engine type (2-cycle vs 4-cycle) and the recommended mix ratio (typically 50:1 or 40:1). Using this in a 4-cycle engine will cause damage.

Key Things to Know

• Pre-measured convenience: Each bottle is exactly 6.4 oz, so you don’t need to measure—just pour one bottle into 2.5 gallons of gas. Great for quick, consistent mixing.
• High-performance formula: Contains a synthetic blend that reduces smoke, deposits, and wear compared to basic 2-cycle oils. It also helps with easier cold starts.
• No installation: This is a fuel additive, not a part. Just mix with gasoline in your fuel can before adding to the tank.
• Common gotcha: Don’t confuse this with STIHL’s 4-cycle engine oil (e.g., for their mowers). Check the label—if it says “2-Cycle” or “2-Stroke,” you’re good for handhelds only.

Should You Buy It

Buy this if you own STIHL 2-cycle equipment and want a reliable, pre-measured oil that meets their warranty requirements. It’s ideal for users who value convenience and engine longevity over cheaper generic oils. Skip it if you need oil for a lawn mower (4-cycle) or if you prefer to measure your own mix from a larger bottle.
