For 2T Maxima 2 Stroke Castor 927 Oil (16oz) With Quick to Mix 2 Stroke Ratio Measuring Bottle

What It Is

This is a 16oz bottle of Maxima Castor 927, a premium 2-stroke racing oil formulated for high-performance, air-cooled engines. It includes a quick-mix measuring bottle for precise fuel-to-oil ratios, ideal for lawn equipment like string trimmers, leaf blowers, chainsaws, and hedge trimmers that require a 2-stroke oil blend.

Fitment & Compatibility

• Engine type: Only for 2-stroke, air-cooled engines. Not for 4-stroke or water-cooled engines.
• Ratio: Works with any mix ratio (e.g., 40:1, 50:1) – the measuring bottle has markings for common ratios.
• Brand/model: Universal fit for any brand (Stihl, Husqvarna, Echo, Ryobi, etc.) that uses pre-mix fuel.
• Before buying: Confirm your equipment’s required oil-to-fuel ratio (check owner’s manual or cap). Castor 927 is not recommended for catalytic converter-equipped engines – check for a CAT symbol on your machine.

Key Things to Know

• Quality: Castor-based oil provides superior film strength and thermal stability, reducing wear in high-RPM engines. It’s a top choice for racing and heavy-use gear.
• Installation: No tools needed – just pour into the measuring bottle, add to gasoline, and shake. The bottle has clear ratio marks (40:1, 50:1) for error-free mixing.
• Gotcha: Castor oil can leave varnish deposits if the engine sits unused for months. Use fuel stabilizer or run the engine dry before storage.
• Shelf life: Unmixed oil lasts years if sealed; once mixed with gas, use within 30 days.

Should You Buy It

Buy this if you own high-performance 2-stroke lawn equipment (e.g., pro-grade trimmers, blowers, chainsaws) and want maximum engine protection and power. It’s overkill for occasional-use, low-RPM machines – a standard synthetic blend is cheaper and sufficient for light duty.
