The shed door rolls up on the first mowing weekend and the mower sits where it wintered, and before the first pass of the season the engine oil gets changed the way the manual asks.

Five filters make the short list below, genuine Briggs and Kohler parts alongside multi-pack replacements, each scored on what its listing states.

Our acreage picks
Briggs & Stratton 492932S Genuine Short Oil Filter 2-1/4 in
Genuine Briggs & Stratton short oil filter, 2-1/4 in tall, listing a 3/4-16 thread and a 1 Year Limited warranty.
Read the full review
The 492932S is the genuine Briggs & Stratton short filter in this group, and its listing is the most complete: 2-1/4 in height, 2.25 in outside diameter, 3/4-16 thread, 6.4 ounces and paper media. The bullets stress verifying filter height and fitment before ordering, and the title calls it the short profile while the item type name says standard, so measure your old filter before you order.
Pros
- Genuine OEM Briggs & Stratton part
- Longest stated warranty here at 1 Year Limited
- Wide engine fitment across Intek and Vanguard V-Twin models
- 2-1/4 in short profile with a listed 3/4-16 thread
Cons
- Short profile only: verify height before ordering a tall filter replacement
- No stated micron rating for the paper media
- No safety certification stated
- Single count, not a multi-pack
Besnor 12-050-01-S Oil Filter 2-Pack
Two-pack 12-050-01-S replacement filter with an M16 x 1.5 thread, paper and steel construction, and a 6 Months stated warranty.
Read the full review
The Besnor two-pack covers the Kohler 12-050-01-S fitment with an M16 x 1.5 thread and 0.56 kg weight listed per filter. The listing states it performs the same as OEM parts, which reads as the maker's claim, and the 6 Months warranty is the second longest stated term in this group.
Pros
- Two filters in the box for two changes or two machines
- 6 Months stated warranty, the second longest here
- M16 x 1.5 thread listed for the metric Kohler fitment
- Paper and steel construction stated
Cons
- Not a genuine OEM part
- Metric thread will not fit engines made for 3/4-16 filters
- Filter height is not stated
- No safety certification stated
TidiRob 52 050 02-S Oil Filter 4-Pack
Four-pack 52 050 02-S replacement filter stating 27 micron filtration, an 8-11 PSI pressure relief valve and a 30 days warranty.
Read the full review
The TidiRob four-pack publishes more stated specs than any other pick here: 27 micron filtration, an 8-11 PSI pressure relief valve and an anti-drain back valve, plus extra capacity and a metal case. The trade is the 30 days warranty, the briefest stated term in this group.
Pros
- Only listing here with a stated micron figure: 27 micron
- 8-11 PSI relief valve and anti-drain back valve stated
- Four filters in the box, the largest pack here
- Wide fitment across Kohler CH, CV, M, MV, KT and SV series
Cons
- Not a genuine OEM part
- Briefest stated warranty here at 30 days
- Thread size is not stated
- No safety certification stated
Briggs & Stratton 696854 Genuine Extended Life Oil Filter
Genuine Briggs & Stratton extended life oil filter, 2-1/4 in tall, with a 90 days stated warranty for defects in material and workmanship.
Read the full review
The 696854 is the second genuine Briggs & Stratton filter here, with extended life in its title and the same 2-1/4 in short profile as the 492932S. One quirk: the spec table lists the item weight as 13.61 g, which is hard to square with the 6.4-ounce 492932S, so trust the title and bullets over the table on this one. The 90 days warranty is also briefer than the 1 Year Limited on the 492932S.
Pros
- Genuine OEM Briggs & Stratton part
- Extended life in the title
- Wide fitment across many Briggs & Stratton engine models
- 2-1/4 in short profile, same height as the 492932S
Cons
- Spec table lists the weight as 13.61 g, which reads as a unit quirk next to the 6.4-ounce 492932S
- 90 days warranty is briefer than the 1 Year Limited on the 492932S
- No safety certification stated
- No stated micron rating
Kohler 52 050 02-S Oil Filter 3-Pack
Genuine Kohler 52 050 02-S three-pack with a listed 3/4-16 thread, paper and plastic/steel media, and no warranty stated on the listing.
Read the full review
The Kohler three-pack is the genuine Kohler 52 050 02-S in a count of 3, with a 3/4-16 thread and 1.6 pounds weight listed. The listing's bullets are garbled page markup rather than product detail, and no warranty term is stated, so the listing asks you to trust the genuine part number alone.
Pros
- Genuine Kohler part
- Three filters in the box
- 3/4-16 thread stated
- Paper and plastic/steel media stated
Cons
- No warranty term stated on the listing
- Listing bullets are garbled page markup with no useful detail
- Filter height is not stated
- No safety certification stated

Buying guide: the best oil filter for lawn mower oil changes
Short or tall profile
The two Briggs & Stratton listings here both use a 2-1/4 in short profile, and their bullets warn to verify filter height and fitment before ordering, especially when replacing short or tall lawn mower oil filter profiles. The title of the 492932S calls it short while its item type name says standard, which is a small contradiction worth flagging: measure your old filter, height included, before you order either one.
Thread size matters
The Briggs filters and the Kohler 52 050 02-S three-pack list a 3/4-16 thread. The Besnor 12-050-01-S lists M16 x 1.5. A filter with the wrong thread will not seat on the engine, so match the thread to your engine’s filter mount and do not assume one size covers every mower on the property.
Genuine or replacement
Three of the five listings are genuine OEM parts: the Briggs & Stratton 492932S and 696854, and the Kohler 52 050 02-S three-pack. The TidiRob four-pack and the Besnor two-pack are replacements that name the OEM numbers they fit. Genuine parts cost more per filter in most cases and carry the maker’s stated warranty terms; replacements win on pack size.
Pack size for a fleet
If the property runs more than one machine, or the mower gets two oil changes in a long season, the multi-packs earn their shelf space: the TidiRob four-pack is the largest pack here, then the Kohler three-pack, then the Besnor two-pack. Both Briggs filters sell as single filters.
Warranty terms
Stated warranty terms here range from 1 Year Limited on the Briggs & Stratton 492932S, to 6 Months on the Besnor two-pack, to 90 days for defects in material and workmanship on the 696854, to 30 days on the TidiRob four-pack. The Kohler three-pack states no warranty term on its listing. If a warranty term matters to you, weigh it the way the scores do.
Pair the filter with the right oil for the job: see our engine oil picks for 4-stroke mowers and the riding mower maintenance guide.
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.
The Acre Score explained
The Acre Score weighs five factors: performance (fitment coverage and stated filtration), build quality (case, gasket and thread as the listing describes them), value (pack size against the stated specs), safety (safety-relevant certifications; none of these listings state one) and warranty (the stated term, if any). The tables and product cards show the scores; the prose below explains what each listing states.
| Product | Acre Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Briggs & Stratton 492932S | 9.7 | 30 | 21 | 20 | n/a | 4 |
| Besnor 12-050-01-S 2-Pack | 9.6 | 29 | 20 | 20 | n/a | 3 |
| TidiRob 52 050 02-S 4-Pack | 9.6 | 30 | 20 | 21 | n/a | 1 |
| Briggs & Stratton 696854 | 9.6 | 28 | 20 | 20 | n/a | 2 |
| Kohler 52 050 02-S 3-Pack | 9.6 | 30 | 20 | 21 | n/a | 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. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.
FAQ: mowing large lots
How do I know which oil filter fits my mower engine?
Match three things from the listing to your engine: the filter height, the thread size and the replacement part numbers. Both Briggs listings here are 2-1/4 in short filters with a 3/4-16 thread, the Kohler three-pack lists 3/4-16 as well, and the Besnor lists M16 x 1.5. Check your engine model against the fitment lists in the listings before you order.
Can I use a replacement filter instead of the genuine OEM part?
The TidiRob and Besnor listings name the OEM part numbers they replace and the engine families they fit. A replacement is a reasonable choice when the fitment list covers your engine model and you want a multi-pack, while a genuine part is the safer choice when you want the maker’s stated warranty term.
Does the filter height matter on a lawn mower engine?
Yes. The Briggs bullets warn to verify filter height and fitment before ordering, especially when replacing short or tall lawn mower oil filter profiles. A tall filter can interfere with the mower’s shrouds or frame where a short filter fits, so measure before you order.
Which of these filters states the longest warranty?
The Briggs & Stratton 492932S states 1 Year Limited, the longest stated term here. The Besnor two-pack states 6 Months, the 696854 states 90 days for defects in material and workmanship, the TidiRob four-pack states 30 days, and the Kohler three-pack states no warranty term on its listing.
Do any of these filters state a micron rating?
Only the TidiRob four-pack states one: 27 micron, plus an 8-11 PSI pressure relief valve and an anti-drain back valve. The other four listings describe filtration in general terms, as helping capture dirt, carbon and metal particles in the oil, without a stated micron figure.
Matching It to Your Property
- One machine, one change a season: the single-count genuine Briggs filters keep the shelf simple.
- Two or more machines, or engines from more than one maker: the multi-packs cover a fleet, with the TidiRob four-pack the largest pack here.
- Kohler-powered machines: match the thread, since the Kohler three-pack lists 3/4-16 while the Besnor replacement lists M16 x 1.5 for the metric fitment.
- Tight engine bays where a tall filter will not clear: the 2-1/4 in short Briggs filters state their height up front.
- Warranty-first buyers: the 1 Year Limited term on the 492932S is the longest stated here, and the Kohler three-pack states none.
