A typical Husqvarna lawn mower oil capacity is around 15 to 20 oz for push mowers, 48 to 64 oz for many riding models, and 64 oz or more for some zero-turns. Sounds simple, but it’s not always that straightforward once engine differences come into play. Some models were sold with more than one engine option, which changes the correct oil amount. The guide below helps you narrow it down faster and avoid filling by guesswork.
Husqvarna Lawn Mower Oil Capacity Chart
If you want quick usable numbers, start with the chart. The goal is to give you practical fill data first, then the service details that matter.
Walk-Behind and Push Mowers
Most push mowers use a small crankcase, so even 2 to 3 extra ounces can push the oil level too high. Fill slowly and confirm at the dipstick.
| Model Series | Engine Brand | Engine Size | Oil Capacity |
|---|---|---|---|
| General Push Models | Various | Various | 15 to 18 oz |
| LC121P / LC121FH | Honda GCV or Briggs & Stratton 725EXi | 160 to 163cc | 18.6 oz or 15 to 18 oz |
| LC140P | Briggs & Stratton 500 Series | 140cc | 15 oz |
| LC221RH / LC221A | Honda GCV190 or Kohler XTX | 187 to 190cc | 18.6 to 20.8 oz |
| HU550FH | Briggs & Stratton | 140cc | 15 oz |
| HU625HWT | Briggs 675EX | 190cc | 19.2 oz |
| HU675AWD | Kohler XT675 | 149cc | 20 oz |
| HU700F / HU700H | Honda GCV190 | 190cc | 18.6 oz |
| HU725AWDH | Briggs & Stratton EXi | 163cc | 18 oz |
| HU800AWD | Honda GCV190 | 190cc | 18.6 oz |
| HD775HW | Various | Various | 18 to 20 oz |
| W448 / W520 Commercial | Subaru EA190V | 190cc | 20.2 oz |
| LB553Se / LB548Se | Briggs & Stratton Pro Series | 160 to 190cc | 17.6 to 19.2 oz |
| LC917 / LC192 | Briggs EXi Series | 140 to 163cc | 15 to 17.3 oz |
| 7021P / 7021R | Honda GCV160 | 160cc | 18.6 oz |
A useful pattern for oil for lawn mower service is simple:
- Small push mowers often use 15 oz
- Many mid-size walk-behind units use 18 oz
- Many 190cc engines use around 18.6 to 20.8 oz
If you are already doing seasonal maintenance, check air filters, spark plugs, and maintenance kits at the same time.
Riding Lawn Mowers and Lawn Tractors
This is the section many people need when searching for Husqvarna riding lawn mower oil capacity. Capacity often follows engine design more than deck size.
| Model Series | Engine Brand | Engine Size | Oil Capacity |
|---|---|---|---|
| YTA18542 | Briggs Intek | 540cc / 18.5 HP | 48 oz |
| YTH18542 | Briggs Intek | 540cc / 18.5 HP | 48 oz with filter, 44 oz without |
| YTH1942 | Various | Various | 48 oz with filter, 42 oz without |
| YTH20K46 | Kohler Courage | 597cc / 20 HP | 51 oz with filter, 35 oz without |
| YTH21K46 | Kohler SV610 | 597cc / 21 HP | 51.2 oz |
| YTH22V46 | Briggs V-Twin 407777 | 724cc / 22 HP | 64 oz |
| YTH24K48 | Kohler SV725 / 7000 Series | 725cc / 24 HP | 64 oz |
| YTH24V48 | Briggs V-Twin | 724cc / 24 HP | 64 oz |
| GTH52XLS | Kawasaki FR Series | 726cc / 24 HP | 67.2 oz |
| TS 242XD | Various | Various | Please check your manual |
| TS 248XD | Various | Various | 52 oz without filter, with filter N/A |
| TS 354XD | Kawasaki FR691V | 726cc | 67.2 oz |
| LTH18538 | Various | Various | 48 oz |
| LTH2038 | Various | Various | 56 oz |
| LGT2654 | Kohler SV735 | 725cc / 26 HP | 64 oz |
| YT48XLS | Kawasaki FR730V | 726cc / 24 HP | 67.2 oz |
| GT52XLS | Briggs Pro Series V-Twin | 724cc | 64 oz |
| TS138L | Briggs & Stratton | 452cc / 18.5 HP | 48 oz |
This is where mistakes happen most often. Two lawn tractors may look similar and still use different engines. That is why lawn mower oil type and capacity should both be checked before service.
If you are changing oil and filter together, keep oil filters, drain plugs, and service parts ready before you start.
Zero-Turn and Commercial Models
Zero-turn capacity can vary sharply by engine brand and engine family, even within the same mower line.
| Model Series | Engine Brand | Engine Size | Oil Capacity |
|---|---|---|---|
| Z142 | Various | Various | Please check your manual |
| Z146 | Various | Various | Please check your manual |
| Z242F | Briggs & Stratton Endurance | Various | 64 oz |
| Z246 | Kohler 7000 Series | 725cc | 64 oz |
| Z248F | Kawasaki FR730V or Kohler | 726cc / Various | Depends on engine brand |
| Z254 / Z254F | Kohler 7000 Series or Briggs Commercial Series | 725cc / 724cc | 64 oz |
| Z272X | Kawasaki FX Series | 852cc+ | 80 oz |
| Z454 | Kawasaki FR691V | 726cc | 67.2 oz |
| Z460 | Kawasaki FS730V | 726cc | 67.2 oz |
| Z4824 | Briggs & Stratton | Various | 51.2 oz with filter, 48 oz without |
| Z554L Professional | Kawasaki FX730V | 726cc | 70.4 oz |
| Z560X / Z560LS / Z572X | Kawasaki FX Series / FX850V | 852cc+ | 80+ oz |
| M-ZT52 | Briggs & Stratton | 724cc / 26 HP | 64 oz |
| M-Z54 / M-Z61 | Kawasaki FX Series | 726 to 852cc | 64 to 80 oz |
| V548 | Various | Various | Please check your manual |
| V554 | Various | Various | Please check your manual |
| V561 | Kawasaki FX850V | 852cc | 80 oz |
| X-One Series | Various | Various | Please check your manual |
| W520 / W500 | Subaru or Kawasaki FJ180V | 179 to 190cc | 19.2 to 20.8 oz |
| W436 | Briggs & Stratton Commercial | 163cc | 19.2 oz |
For higher-hour machines, it helps to stock engine oil, replacement filters, and air cleaner elements before the season starts.
What Kind of Oil Does a Lawn Mower Take?
When people search for what kind of oil a lawn mower takes, they often need two answers: oil type and oil amount. Capacity tells you how much. Viscosity tells you what to pour.
For many Husqvarna petrol mowers, SAE 30 is a standard warm-weather choice. Temperature still matters:
- Below 40°F or 4°C, SAE 30 can make starting harder
- If SAE 30 is used at low temperatures, lubrication may be poor
- 10W-30 works across a wider temperature range
- In hot conditions, 10W-30 may increase oil consumption
- Synthetic oil can be used across all temperatures if approved for the engine
- Use detergent oil rated SF, SG, SH, SJ, or higher
For small engines in general, these are the common choices:
| Oil Type | Best Use |
|---|---|
| SAE 30 | Warm weather, common for small engines |
| SAE 10W-30 | Mixed temperatures, easier cold starts |
| Synthetic SAE 5W-30 | Broad temperature range |
| SAE 5W-30 | Very cold conditions |
| 15W-50 | Continuous heavy use on some engines |
If your mower uses a Briggs engine, many walk-behind models are often 15 oz or 18 oz, while many riding models are often 48 oz or 64 oz. For a Honda-powered push mower, a common figure is around 18.6 oz, but the engine tag and dipstick should still guide the final fill.
This is also a good time to inspect fuel filters, engine gaskets, and tune-up parts for a more complete service.
How To Fill the Correct Amount?
A Husqvarna lawn mower oil capacity table gets you close, but the dipstick is still the final check.
Use This Fill Method
- Park the mower on level ground
- Let the engine cool briefly
- Clean the area around the filler cap
- Drain the old oil fully
- Add about 80 to 90 percent of the listed capacity
- Wait a moment for the oil to settle
- Check the dipstick
- Add small amounts until the oil reaches full
This method works because not every engine drains the same way. A filter change also affects final volume.
How Often To Check and Change?
A practical service schedule looks like this:
| Usage Level | Oil Check | Oil Change |
|---|---|---|
| Regular home use | Every 5 hours of runtime | Every 50 hours or once per season |
| Dusty or heavy mowing | More often | About every 25 hours |
| Commercial use | Daily or very often | Every 15 to 25 hours |
| New mower first service | Early check advised | After first 5 hours |
If you mow in heat, dust, or long sessions, shorten the oil change interval. It also makes sense to replace spark plugs, air filters, and oil filters together when needed.
Mistakes That Cause Oil Problems
Most oil issues come from using the wrong amount, not just the wrong grade.
Overfilling
Too much oil can cause:
- Smoke from the muffler
- Foam in the crankcase
- Oil leaks
- Dirty intake parts
- Weak engine performance
Underfilling
Too little oil can lead to:
- High engine temperature
- Fast internal wear
- Weak lubrication on slopes
- Shorter engine life
Using Mower Model Alone
Some Husqvarna mowers were sold with different engine suppliers. That is why Husqvarna lawn mower oil capacity chart data should be checked against the engine family whenever possible.
Ignoring the Dipstick
Published capacity helps, but the final fill should always match the dipstick full mark, not just the bottle measurement.
Final Words
A correct oil fill helps your mower run cleaner, cooler, and with less wear over time. The safest approach is to use the chart for reference, then verify the final level on the dipstick. If you’re taking care of more than just the oil change, FridayParts also carries aftermarket parts that can be useful for routine mower maintenance.
