How much oil should I put in my snowblower?
For the MTD snow thrower model 31AM63FF752, fill the engine with oil to the FULL mark on the dipstick with the machine on a level surface. Most snowblower engines take about 18 to 28 oz of oil, but the correct fill level for your engine is the dipstick reading in the 31AM63FF752 operator’s manual.
- Park the snowblower on a flat, level surface and let the engine cool.
- Remove the dipstick, wipe it clean, then reinsert fully.
- Add oil slowly, checking the dipstick often.
- Stop when the oil reaches the FULL mark (do not overfill).
- Check oil with the machine level; a tilted housing gives a false reading.
- Add small amounts near the end; overfilling can cause smoking and poor running.
- Wipe spills off the engine and frame before starting.
- Use a clean funnel; dirt in the crankcase shortens engine life.
- Recheck the level after a short run and cool-down.
Oil viscosity depends on temperature. Many snowblower engines run best on multi-viscosity oil in cold weather.
| Outdoor temperature | Typical oil choice | Why it helps |
|---|---|---|
| Below freezing | 5W-30 | Easier cold starts, better flow |
| Mild winter temps | SAE 30 | Stable viscosity in warmer conditions |
For the exact viscosity and any special requirements for your engine, follow the 31AM63FF752 operator’s manual.
Correct oil level protects the crankshaft, piston, and bearings. Too little oil accelerates wear; too much oil can foam, leak, or cause hard starting and smoke.

Where is the model number on a MTD snowblower?
On the MTD snow thrower model 31AM63FF752, the model number is printed on the equipment ID label; it’s commonly located on the rear of the unit near the wheel area. Use that full model number (and the serial number) anytime you order parts or request service. See the 31AM63FF752 operator’s manual.
Check these common label locations first (clean off snow, salt, and grime so the print is readable):
- Rear of the snowblower near the wheels (most common)
- Back of the frame behind the engine
- Lower rear panel near the axle area
- Side of the frame rail near the auger housing
- Under or near the handle support area
The ID label typically shows both fields below:
| Label field | What it’s used for | Example format |
|---|---|---|
| Model number | Identifies the exact build and parts list | 31AM63FF752 |
| Serial number | Tracks production run for service and support | Varies |
- Write the model number exactly as printed (letters and numbers).
- Take a clear photo before the label fades further.
- If the label is scratched, try a flashlight at an angle to make the characters stand out.
- Keep the model and serial number together in your maintenance records.
MTD operator’s manuals often cover multiple 500 and 600 Series two-stage snow thrower variations, so the exact model number is what ensures you get the correct parts, adjustments, and service information for your specific machine.

Who makes MTD snowblower engines?
MTD snowblowers (including model 31AM63FF752) use engines supplied by an engine manufacturer; the specific maker can vary by production run and is identified on the engine itself. For engine specs, service, and warranty coverage, we follow the engine manufacturer information referenced in the 31AM63FF752 operator's manual.
Use the engine’s ID label, not the snowblower brand decal.
- Look for a label on the recoil starter housing, valve cover, or blower housing
- Record the engine brand (example: Briggs and Stratton, Tecumseh, etc.)
- Record the engine model and type/spec numbers (or a full engine model code)
- Match those numbers when ordering engine parts like spark plugs, air filters, or carburetor parts
- Use the engine maker’s manual for tune-up specs (spark plug gap, oil type, governor settings)
The operator’s manual for MTD two-stage snow throwers explains that engine-related issues (performance, power rating, specifications, warranty, and service) are handled by the engine manufacturer, and it directs you to the engine maker’s Owner’s/Operator’s Manual that came with the machine. That is the most reliable way to confirm who built your engine.
| What you need | Where to find it | Why it matters |
|---|---|---|
| Engine manufacturer | Engine label/badge | Tells you which manual and parts system to use |
| Engine model and spec | Engine label stamping | Ensures correct carburetor, ignition, and gasket parts |
| Snowblower model 31AM63FF752 | Snowblower ID tag | Ensures correct chassis parts like cables, skid shoes, and shave plates |
Ordering the right parts depends on using the correct identifier: MTD 31AM63FF752 for snow thrower chassis parts, and the engine manufacturer model/spec for engine parts and engine warranty service.
