STIHL OIL MIX 1 GALLON HIGH PERFORMANCE ULTRA 2-CYCLE ENGINE 6 PACK

What It Is

This is a 6-pack of STIHL High Performance Ultra 2-cycle engine oil, pre-mixed at 50:1 in 1-gallon containers. It’s designed for STIHL handheld equipment like chainsaws, trimmers, blowers, and hedge trimmers—any air-cooled 2-cycle engine requiring a synthetic blend.

Fitment & Compatibility

• Brand/Model: Only for STIHL 2-cycle engines (not for 4-cycle or non-STIHL equipment unless the manual explicitly allows 50:1 synthetic mix).
• Fuel Ratio: Pre-mixed at 50:1 (2.6 oz oil per gallon of gas). Do not add extra oil—this is ready-to-use.
• Engine Type: Air-cooled 2-cycle only. Not for outboard motors or water-cooled engines.
• Storage: Fuel stabilizer included, but still use within 30 days of opening for best performance.
• Check: Verify your equipment’s fuel cap and tank size (1 gallon fits most handheld tanks). No deck size or mower-specific fitment applies.

Key Things to Know

• Quality: STIHL’s highest-tier synthetic oil—reduces carbon buildup, extends engine life, and meets JASO FD/ISO-L-EGD standards.
• Installation: Zero difficulty—just pour directly into the fuel tank. No measuring or mixing required.
• Gotcha: Do not use in 4-cycle engines or any equipment not rated for 50:1 mix. Also, 1 gallon per container means you’ll need to store opened containers upright in a cool, dry place.
• Price: At ~$4.31 per gallon (6-pack), it’s cheaper than buying single quarts, but verify it’s cheaper than your local dealer’s price.

Should You Buy It

Buy this if you own multiple STIHL 2-cycle tools and want a guaranteed correct mix with premium synthetic protection. It’s ideal for pros or heavy users who burn through fuel quickly, but skip it if you have non-STIHL 2-cycle engines or only use a trimmer once a month—single quarts or separate oil might be more cost-effective.
