TRIAX Synergy SRT 5W-30 - Full Synthetic, Friction Modified Engine Oil - 20K Miles, API SP Licensed, 3x Wear Protection - Nano Boron and Moly Friction Modified (1 Quart)

What It Is

TRIAX Synergy SRT 5W-30 is a full synthetic, friction-modified engine oil designed for high-performance air-cooled small engines in lawn mowers, zero-turn mowers, and commercial turf equipment. It’s formulated to extend oil change intervals up to 20K miles in compatible engines, with added Nano Boron and Moly for reduced wear and heat protection.

Fitment & Compatibility

• Check your engine manual for recommended viscosity (5W-30) and API SP or higher rating—this oil meets API SP, SN Plus, and ILSAC GF-6 standards.
• Works with most air-cooled engines from Briggs & Stratton, Kawasaki, Kohler, Honda, and Toro, including those requiring synthetic 5W-30.
• Not for engines that specify SAE 30, 10W-30, or diesel oil unless the manual explicitly allows 5W-30 synthetic—verify oil cap or dipstick markings.
• 1 quart is typical for most push mowers (18-22 oz capacity) or zero-turn models (1.5-2 quarts); measure your crankcase capacity before buying.
• OEM vs aftermarket: This is a premium aftermarket oil; no compatibility issues with OEM filters or gaskets.

Key Things to Know

• Installation difficulty: Easy—drain old oil, replace filter (if applicable), and refill to dipstick mark. No special tools needed.
• 20K-mile claim assumes clean, low-dust, moderate-load operation. For mowers in heavy debris or high heat, change at 100-150 hours or annually, whichever comes first.
• Nano Boron and Moly reduce friction and heat, beneficial for engines running at sustained high RPM (e.g., zero-turn mowers) or in hot climates.
• API SP licensed ensures compatibility with modern emissions systems and reduces low-speed pre-ignition risk—good for newer engines.

Should You Buy It

Buy this if you want extended oil life and maximum wear protection for a high-hour or commercial mower with a 5W-30 requirement, and you’re willing to pay a premium over conventional oil. Skip it if your engine calls for SAE 30 or you prefer a cheaper, shorter-interval oil for a basic push mower.
