Maxima SynBlend Ester 4T Semi-Synthetic Engine Oil – 20W50 | Case (12 x 1L) | 35901B

Maxima SynBlend Ester 4T — a semi-synthetic, ester-based 4-stroke engine oil in 20W50 viscosity. Sold as a case of 12 x 1L bottles. Formulated for motorcycle and powersports engines running wet clutch systems. Designed for optimum engine protection, peak performance, and consistent clutch feel across operating temperatures.

Ester-Based Semi-Synthetic Formulation

SynBlend uses an ester basestock in its semi-synthetic formulation. Ester molecules are polar — they adhere to metal surfaces rather than simply floating in suspension like conventional mineral or standard PAO synthetic oils. This adhesion provides a superior oil film on engine components during startup, under high load, and at temperature extremes, reducing metal-to-metal contact and wear. The ester basestock also delivers excellent viscosity stability across operating temperatures — the oil maintains consistent film thickness whether the engine is cold or fully heat-soaked after extended use.

Wet Clutch Compatible

Many 4-stroke motorcycle and powersports engines share oil between the engine and the wet clutch pack. Automotive engine oils contain friction modifiers designed to reduce friction in car engines — these same modifiers cause clutch slip in a wet clutch application. Maxima SynBlend 4T is formulated without automotive-style friction modifiers, preserving wet clutch engagement and feel. The result is positive, consistent clutch action without slip. Confirm JASO MA rating compatibility with your engine manufacturer’s requirements.

20W50 Viscosity

20W50 is a higher-viscosity grade suited to engines that run hotter or require a thicker oil film for adequate protection. Common applications include:

• Air-cooled 4-stroke motorcycle engines — V-twins, singles, parallel twins in high-ambient conditions
• High-displacement 4-stroke powersports engines
• Older engines with higher tolerances that benefit from a thicker oil film
• High-performance 4-stroke engines producing significant heat under sustained use

Always refer to your engine manufacturer’s recommended viscosity grade before selecting an oil weight.

Advanced Additive System

Maxima’s proprietary additive package keeps the engine running clean — dispersants and detergents suspend combustion byproducts and prevent deposit buildup, extending engine life and reducing maintenance intervals between oil changes.

4-stroke motorcycle and powersports use only — not for automotive applications. Wet clutch compatible — do not substitute automotive oil in wet clutch engines. Verify viscosity grade and JASO specification against your engine manufacturer’s requirements before use. Dispose of used oil responsibly at a certified recycling facility.
