Craftsman Full Syn 2 Cycle Oil CMXGAW5126, 2.6oz, Retail Ready Case of 12

What It Is

This is Craftsman CMXGAW5126, a 2.6-ounce bottle of full synthetic 2-cycle oil, sold in a case of 12. It’s pre-measured for mixing with 1 gallon of unleaded gasoline at a 40:1 ratio, designed for small engines like Craftsman trimmers, leaf blowers, chainsaws, and other 2-cycle handheld equipment.

Fitment & Compatibility

• Fuel ratio: Only for engines requiring a 40:1 mix (2.6 oz oil per 1 gallon gas). Do not use for 50:1 or 32:1 engines without adjusting ratio.
• Engine type: Exclusively air-cooled, 2-cycle engines. Not for 4-cycle mowers, tillers, or any 4-stroke equipment.
• Brand fit: OEM for Craftsman, but compatible with any brand (Poulan, Husqvarna, Echo, Ryobi, etc.) that specifies 40:1 mix in the manual.
• Measurement check: Each bottle is exactly 2.6 oz. If your gas can is smaller than 1 gallon, you’ll need to measure accordingly (e.g., 1.3 oz for ½ gallon).
• Storage: Case of 12 individual bottles—no mixing jug needed. Each bottle has a resealable cap for partial use.

Key Things to Know

• Quality: Full synthetic formulation reduces smoke and carbon buildup compared to conventional 2-cycle oil. Meets ISO-L-EGD and JASO FD standards for high-performance engines.
• Installation difficulty: Dead simple—pour entire bottle into 1 gallon of fresh unleaded gas, shake well, and use immediately. No measuring required.
• Common gotchas:
  • Do not use with ethanol-blended gas higher than E10.
  • Do not substitute for pre-mixed fuel (e.g., TruFuel) if your engine requires a different ratio.
  • Bottles are small—easy to lose in a toolbox. Store in a cool, dry place away from heat.
• Shelf life: Unopened oil lasts 3–5 years. Once mixed, use fuel within 30 days.

Should You Buy It

Buy this case if you own multiple 40:1 2-cycle tools and want a no-mess, pre-measured synthetic oil that’s easy to store and use. It’s a solid value for consistent performance and engine protection, especially if you prefer Craftsman brand loyalty. Skip it if your equipment uses a different mix ratio or if you only need a single bottle.
