Owner’s manual
Should I use 40 1 or 50 1 fuel for a chainsaw?
For the Craftsman 358360260 gas chainsaw, we recommend a 40:1 fuel mix. This model’s manual specifies mixing 3.2 ounces of quality synthetic 2-cycle (air-cooled) oil with 1 gallon of unleaded gasoline; using 50:1 reduces lubrication and can increase wear.
Recommended fuel mix for model 358360260
Use fresh, unleaded gasoline mixed with a good-quality synthetic 2-cycle air-cooled engine oil.
- Mix at 40:1 for this Craftsman chainsaw model
- Measure 3.2 oz oil per 1 gallon gas
- Mix fuel outdoors in an approved, marked container
- Wipe up spills before starting
- Move the saw at least 10 feet from the fueling area before starting
For the exact wording and safety steps, follow the 358360260 owner's manual.
40:1 vs 50:1: what changes
| Mix ratio | Oil per 1 gallon gas | What it means | Best use case |
|---|---|---|---|
| 40:1 | 3.2 oz | More lubrication | Correct ratio for Craftsman 358360260 |
| 50:1 | 2.6 oz | Less lubrication | Only when a specific engine manual requires it |
Why it matters
The oil in the fuel mix lubricates internal engine parts. Running leaner on oil than the manufacturer specifies (such as 50:1 in a 40:1 engine) can accelerate piston and cylinder wear and shorten engine life.
Related maintenance tip (easy to miss)
This model also relies on proper bar-and-chain lubrication. We recommend filling the bar oil tank every time you fill the fuel tank; the manual notes the saw typically uses about one tank of bar oil per tank of fuel.
If you are troubleshooting hard starting after fueling, use tips for a hard to start chainsaw to check common causes like stale fuel, incorrect mix, and priming technique.

Look for the model number in one of these common locations:
- On the starter housing or rear handle area
- Near the fuel tank or oil tank
- On a printed or stamped ID label on the engine housing
- In the parts list section of the manual
Why the model number format can look different
Craftsman chainsaw model numbers are commonly shown in two formats that mean the same thing.
| You might see | It means |
|---|---|
| 358.360260 | Standard label/manual format |
| 358360260 | Same model number without the dot (often used online) |
Why it matters
Using the exact model number helps us match the correct parts and diagrams for your saw, especially for items like the carburetor, fuel line, chain, bar, and clutch components.
Parts that commonly require the exact model match
When ordering or troubleshooting, the model number is most important for:
- Fuel system parts (fuel line, primer bulb, fuel tank cap)
- Oiling system parts (oil pump, oil filter)
- Ignition parts (ignition coil)
- Cutting system parts (bar and chain)

Where is the model number on a chainsaw?
On the Craftsman chainsaw model 358360260, the model number is typically printed on the product identification label or ID tag on the saw body. On this model, you will also see it shown in the documentation as Model No. 358.360260 in the 358360260 owner's manual.
Where to look on the saw
Check these common label locations first (clean off oil and sawdust so the print is readable):
- On the rear handle area near the trigger and throttle lock
- On the starter housing (recoil cover) side of the saw
- Near the bar mount area on the side cover or chassis
- On the underside of the saw body near the fuel and oil tanks
- On a small ID tag near the muffler side (often easiest to spot with a flashlight)
What the model number helps you match
Using the exact model number (358360260) matters because it ties your saw to the correct parts list and specs, such as the 16-inch bar setup and the correct fuel and oil system components.
| What you need | What to use | Example for this model |
|---|---|---|
| Ordering parts | Model number | 358360260 |
| Confirming setup/specs | Owner documentation | 358360260 owner's manual |
| Fuel system repairs | Exact part match | Ayp lawn & garden equipment fuel line, large 530069216 |
If the label is missing or unreadable
You can still identify the saw accurately using a few cross-checks:
- Compare the bar length and general layout to the parts diagrams for 358360260
- Match key components (fuel line routing, primer bulb style, clutch area) to the listed parts
- Use the manual’s model identification (it lists Model No. 358.360260)
Why it matters
Chainsaws often look similar across model families, but small differences in the fuel line, carburetor mounting, clutch drum, or oiling system can cause wrong-part fit. Confirming the model number first prevents repeat repairs and fuel or oil leaks.
