Description

Maxima Racing Oil Castor 927 – High-Performance 2-Stroke Premix Oil


Premium Castor-Based Oil for Serious 2-Stroke Performance


Maxima Castor 927 is a high-performance, castor-based, ester-fortified 2-stroke engine oil designed to deliver unmatched protection and power under extreme conditions. Ideal for racing, vintage, or high-RPM 2-stroke engines, Castor 927 combines the benefits of traditional castor oils with modern synthetic technology and a proprietary additive system for cleaner, more reliable performance.


Formulated for Power, Protection, and Clean Running

Maxima’s exclusive formulation blends three critical elements:

  • Highly refined castor oil for natural lubricity and high-temp resilience
  • Advanced synthetic esters for excellent film strength and surface adhesion
  • Ash-free additive system to minimize deposits, gum, and corrosion

Key Benefits:

  • Outstanding film thickness and tenacity under high load
  • Excellent carbon and vaporization resistance
  • Reduces gum, varnish, and deposit formation
  • Helps maintain cleaner power valves compared to other Castor Oils
  • Biodegradable and smells great with low smoke output


Application & Use

Designed For:

  • High-performance carbureted 2-stroke gasoline engines
  • Vintage and modern air-cooled racing engines
  • Premix systems only – not for oil injection

Mix Ratio:
Safe to use at any OEM-recommended premix ratio

Not Recommended For:

  • Fuel-injected 2-stroke engines
  • Oil injection systems (premix only)


Why Choose Castor 927?

Compared to other castor-based oils, Maxima Castor 927 offers superior:

  • Clean burn with reduced carbon buildup
  • Corrosion and rust protection—even in storage
  • High-temp stability for long, hard pulls
  • Compatibility with both leaded and unleaded fuel

It’s especially well-suited for:

  • Dirt bikes
  • Vintage race engines
  • Karting and minibikes
  • High-RPM air-cooled 2-strokes


Pro Tips for Best Performance

  • Always shake your fuel/oil mixture to ensure full blending before filling your tank.
  • Tune your carburetor properly—running overly rich can cause unnecessary carbon buildup even with clean-burning oil.
  • If you're running a modern, water-cooled 2-stroke engine (e.g., road racing or high-end motocross), consider Maxima Formula K2 for cleaner combustion and superior compatibility.

FAQ

What makes Maxima Castor 927 different from other 2-stroke oils?

Maxima Castor 927 combines refined castor oil, synthetic esters, and a proprietary ash-free additive system for maximum protection, superior lubrication, and cleaner performance—especially in high-RPM racing environments.


Is Castor 927 safe to use in my vintage 2-stroke engine?

Yes. Castor 927 is especially suited for air-cooled, carbureted 2-stroke engines, including vintage bikes, karts, and minibikes. Its high film strength and anti-corrosion properties are ideal for older, high-strung engines.


Can I use Maxima Castor 927 in an oil injection system?

No. Castor 927 is a premix-only 2-stroke oil and is not compatible with oil injection systems. It must be manually mixed with fuel before use.


What is the recommended mix ratio for Castor 927?

Maxima Castor 927 is safe to use at any manufacturer-recommended premix ratio, typically ranging from 32:1 to 50:1depending on your engine and application.


Does Castor 927 produce a lot of smoke or residue?

While it’s based on castor oil, Castor 927 runs much cleaner than traditional castor oils. It produces minimal smoke, resists carbon buildup, and keeps power valves cleaner—especially when properly tuned.


Is Castor 927 biodegradable?

Yes. Maxima Castor 927 is biodegradable, making it a more environmentally friendly option compared to many traditional 2-stroke oils.


What’s the difference between Castor 927 and Maxima Formula K2?

  • Castor 927: Best for vintage or air-cooled carbureted 2-stroke engines; castor-based for excellent high-temp protection.
  • Formula K2: Best for modern, water-cooled 2-strokes (e.g., motocross or road racing); cleaner-burning synthetic formulation.


Can Castor 927 be used with both leaded and unleaded fuel?

Yes. Castor 927 is fully compatible with both leaded and unleaded gasoline.
