Engine Oil Quart Fits Troy Bilt Replaces 215308

What It Is

This is a 1-quart bottle of engine oil designed for Troy-Bilt lawn mowers, replacing OEM part number 215308. It’s a standard maintenance item for 4-cycle engines, used for oil changes to keep the engine lubricated and running smoothly.

Fitment & Compatibility

Before buying, confirm your Troy-Bilt model has a 4-cycle engine (most walk-behind mowers do). Check your owner’s manual or the engine brand (e.g., Briggs & Stratton, Kohler) to verify oil type—this is typically SAE 30 or 10W-30, but some engines require synthetic or specific viscosity. Measure your oil capacity: most Troy-Bilt mowers take 18–20 oz, so a quart (32 oz) will cover one change with some left over. Ensure the bottle cap matches your fill spout; it’s usually a standard screw-top. Avoid using in 2-cycle engines (which require oil-gas mix) or zero-turn mowers with larger oil capacities.

Key Things to Know

• Quality: Standard conventional oil; fine for routine changes in residential mowers. Not for extreme temperatures or high-hour commercial use.
• Installation: Easy—drain old oil (warm engine, tip mower or use drain plug), refill to dipstick mark. No special tools needed.
• Gotcha: Overfilling can cause engine damage—use the dipstick, not the whole quart. Dispose of old oil properly at a recycling center.
• Gotcha: If your mower has a Briggs & Stratton engine, double-check that this oil meets their spec (often SAE 30 for warm weather). Some newer engines require 5W-30 synthetic.

Should You Buy It

Buy it if you need a quick, affordable oil change for a standard Troy-Bilt push mower and don’t want to hunt for the exact OEM part. It’s a solid choice for basic maintenance, but if your mower has a high-performance engine or you mow in cold climates, consider a synthetic alternative instead.
