For your Craftsman lawn tractor model 917288123, use SAE 30 engine oil when operating above 32°F, and SAE 5W30 when operating below 32°F. Use a high-quality detergent oil that meets API service classification SG-SL; see the owner's manual for the full viscosity chart and maintenance details.

Oil type and capacity (model 917288123)

Use the oil grade that matches your typical mowing temperature range.

Operating temperature	Recommended oil type	Notes
Above 32°F	SAE 30	Best for warm-weather mowing
Below 32°F	SAE 5W30	Helps cold starting; check level more often

Oil capacity:

• With filter: 56 oz
• Without filter: 48 oz

How we recommend maintaining engine oil

Good oil habits prevent hard starting, smoking, and premature engine wear.

• Check the oil level before starting and after every 8 hours of operation.
• Change oil every 50 hours of operation or at least once a year.
• Change oil when the engine is warm (it drains more completely).
• Keep dirt out of the crankcase when removing the dipstick or drain cap.
• Tighten the oil fill cap/dipstick securely after each check.

Why it matters

Using the correct SAE viscosity for the temperature keeps the engine properly lubricated. Multi-viscosity oils (like 5W30) improve cold starts, but in warmer conditions they can increase oil consumption, so checking the level regularly helps protect the engine.
