Buying guide: choosing a best oil filter for lawn mower under 20
Match the part number to the engine
Part number is the first check, since these filters are vehicle specific fits. The Stens replaces Kohler 52 050 02-S and fits CH, CV, M, MV and K series engines, the Kawasaki replaces 49065-7007 and 49065-0721 for select 22-24 HP engines from 2009 and later, and the Briggs is a genuine 492932 for pressure lubrication engines. The HOODELL filters replace Kohler 52 050 02-S and 12 050 01-S across CH, CV, KT, SV and MV series, plus Cub Cadet, Husqvarna, Craftsman and Toro models named in their listings. Match the number on your old filter before ordering.
Thread, height and micron
Thread, height and micron decide whether the filter fits and what it catches. Threads stated are 3/4-16 on the Stens and the Briggs, and M16 x 1.5 on both HOODELL filters, while the Kawasaki thread is not stated. Heights stated are 3 7/16 in on the Stens, 2-1/4 in on the Briggs, 2-5/8 in on the HOODELL 12 050 01-S and 3-1/8 in on the HOODELL 52 050 02-S, while the Kawasaki height is not stated. Micron figures stated are 29 on the Stens and 27 on both HOODELL filters, while the Kawasaki and Briggs listings state no micron figure. The Stens also states an 8-11 psi pressure relief valve with an anti-drain valve.
Single filters and 2-packs
Pack size decides whether you have a spare on the shelf. The Stens and the Kawasaki are single filters, while the Briggs and both HOODELL filters are 2-packs. The HOODELL listings state the 2-pack filters are for back up, which suits a property with more than one machine. A single genuine filter suits a reader who wants the exact OEM part for one engine. For more mower care gear, see the battery terminal brush cleaner and lithium battery maintainer guides, and browse all mower maintenance guides.
Read the warranty line
Only two listings state a warranty term: the Kawasaki at 1 year and the Stens at 30 days. The Briggs and both HOODELL listings state no warranty term.
Read the manual, keep children and pets out of the yard while you work, wear eye and hearing protection and sturdy footwear, and never exceed the slope rating of your machine. Refuel only with the engine off and cool. See CPSC lawn mower safety. Read our Safety Disclaimer.
Matching It to Your Property
- For Kohler engines, the Stens and HOODELL filters cover CH, CV, KT, SV and MV series, per their listings.
- For a Kawasaki engine, the Kawasaki filter fits select 22-24 HP engines from 2009 and later.
- For a Briggs and Stratton engine, the genuine 492932 2-pack fits pressure lubrication engines.
- For storage, the HOODELL 2-packs state filters for back up, per their listings.
- Assembly is not stated for any of the five, so do not assume tools or time.
The Acre Score explained
The Acre Score weighs performance (fit range, micron figure, valves), build (case, seal, materials), value, safety (pressure relief valve and anti-drain valve where stated) and warranty. A factor the listing does not state scores zero. Only two listings state a warranty term: the Kawasaki at 1 year and the Stens at 30 days.
| Product | Acre Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Stens 055-109 | 9.6 | 30 | 20 | 20 | 7 | 1 |
| Kawasaki 49065-0721 | 9.5 | 29 | 20 | 19 | 0 | 3 |
| HOODELL 52 050 02-S | 9.5 | 30 | 20 | 21 | 0 | 0 |
| HOODELL 12 050 01-S | 9.5 | 29 | 20 | 21 | 0 | 0 |
| Briggs 492932s | 9.4 | 28 | 19 | 21 | 0 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
