SAE 30 is a single-grade oil recommended for use in Toro self-propelled lawn mowers. It is a non-detergent oil with a viscosity of 30 at 100 degrees Fahrenheit. SAE 30 oil is suitable for use in most climates, but it may be too thin for use in cold climates. If the temperature in your area is consistently below 40 degrees Fahrenheit, you should use a heavier oil, such as SAE 10W-30.
