Briggs & Stratton 5W30 Synthetic Motor Oil Kit w/ 492932s Filter

What It Is

This is a maintenance kit from Briggs & Stratton containing a 32-ounce bottle of 5W30 synthetic motor oil and a 492932S oil filter, designed for air-cooled small engines in lawn mowers, tractors, and zero-turn mowers.

Fitment & Compatibility

Before buying, verify your engine accepts 5W30 viscosity—common in Briggs & Stratton Vanguard, Intek, and Extended Life Series engines, but not for older flathead or side-valve models that use SAE 30. The 492932S filter fits many Briggs engines with a spin-on filter (thread size 3/4-16, gasket diameter ~2.25 inches). Check your owner’s manual or current filter number; cross-references include OEM 492932, 841966, and 698369. This kit is OEM Briggs—no aftermarket guesswork. Not for push mowers with splash-lube systems (no filter). Measure your filter base diameter and thread pitch to confirm, or match the existing filter’s part number.

Key Things to Know

• Quality: Synthetic 5W30 provides better cold-start protection and high-temp stability than conventional oil—ideal for variable climates or heavy use.
• Installation: Easy DIY: drain old oil, replace filter (hand-tighten ¾ turn after gasket contacts), fill with 32 oz (check dipstick for exact level). No special tools needed.
• Gotchas: The 32 oz bottle may not fill all engines to full—some Vanguard twins need ~48 oz. Have extra 5W30 on hand. Never overtighten the filter; it can warp the gasket.
• Frequency: Change oil every 50 hours or seasonally; replace filter every other change for most residential use.

Should You Buy It

Buy this if you own a Briggs & Stratton engine that requires 5W30 and a spin-on filter—it’s a convenient, OEM-matched kit that simplifies maintenance and ensures proper additive formulation. Skip it if your engine uses SAE 30 or has a different filter thread.
