Spartan Recommended Oil Type

Spartan mower engines generally require SAE 10W-30 or SAE 20W-50, depending on your operating temperature and engine type. Here’s a quick breakdown:

• Kawasaki engines: Typically SAE 10W-30 or SAE 20W-50
• Briggs & Stratton/Vanguard: SAE 5W-30 or 10W-30 for cold starts; 15W-50 or 20W-50 for hotter climates

When to Change the Oil

Routine oil changes are key to maintaining performance. Here’s a general guideline:

• After the first 5 hours: Initial break-in period
• Every 50-100 hours: For regular use
• More frequently: In dusty or hot environments

Always replace the oil filter (if equipped) during oil changes for best results.
