Maintenance (2 Qts) Synthetic Blend 10W30 Kohler Engine Oil & (1) Kohler 12 050 01-S1 Oil Filter

What It Is

This kit combines 2 quarts of synthetic blend 10W30 Kohler engine oil with one OEM Kohler 12 050 01-S1 oil filter. It’s designed for routine oil changes on Kohler Command, Courage, and other small engines found in lawn tractors, zero-turn mowers, and walk-behinds.

Fitment & Compatibility

Before buying, verify your engine model—this oil filter (Kohler part 12 050 01-S1) fits most Kohler single-cylinder and V-twin engines with a spin-on filter, including Command (CH, CV), Courage (SV), and some Aegis series. The 10W30 oil is suitable for 4-cycle Kohler engines requiring SAE 10W30 (check your owner’s manual). Not compatible with Kohler engines using a different filter thread size (e.g., some older models) or requiring 5W30 or 20W50. Measure your current filter’s diameter and thread pitch (3/4-16 is standard) to confirm. This kit does not fit non-Kohler engines (Briggs & Stratton, Honda, Kawasaki) unless cross-referenced.

Key Things to Know

• Quality: OEM filter ensures proper bypass valve pressure and micron rating—aftermarket filters may restrict oil flow or fail early. Synthetic blend oil offers better cold-start protection than conventional.
• Installation: Easy DIY job—drain old oil, remove old filter (hand-tighten new one after coating gasket with fresh oil), refill with 2 qts (most Kohler engines take ~2 qts with filter change). No special tools needed.
• Common gotchas: Over-tightening the filter can damage the gasket—hand-tighten plus 1/4 turn only. Double-check oil capacity: some larger Kohler engines (e.g., CH740) may need 2.5 qts—have an extra quart on hand.
• Storage: Oil and filter are shelf-stable for years if kept sealed and dry—good to stock for multiple changes.

Should You Buy It

Buy this kit if you own a Kohler-powered mower and want a one-stop, OEM-matched oil change set with proven reliability. It’s ideal for DIYers who value convenience and correct fitment over buying separate parts. Skip it if your engine requires a different oil weight or filter type, or if you prefer a full synthetic oil for extreme conditions.
