Typical Motor Oils Used in Lawn Tractors
SAE 30 – Best for warmer temperatures. Traditional choice for small engines.
10W-30 – More versatile; good for varying temps, helps with easier starts in cooler weather.
5W-30 – Ideal for colder climates; helps with cold starts and smoother operation.
Synthetic 5W-30 – Best protection, wider temp range, longer oil life, better for heavy use or commercial-grade machines.
🧰 What I Use (or Recommend)
For older Briggs & Stratton or Kohler engines: SAE 30 in summer, 10W-30 if temps fluctuate.
For newer engines or extended intervals: Full synthetic 5W-30 (like Mobil 1 or Royal Purple).
Commercial or heavy-duty use: Synthetic all the way.
🔄 How Often to Change
Every 25-50 hours of use, or once a season.
Always change the oil before winter storage.
