Frequently Asked Questions (FAQs)

1. Are all lawn mower oil filters the same?

not all riding mowers have an oil filter. Generally speaking, the smaller engines do not have an oil filter instead they rely on replacing the oil at more regular intervals.

2. What kind of oil do you use on a lawn mower filter?

SAE 10W-30 is best for varying temperature ranges and is best for starting in cold climates. The trade off here is the potential for higher oil consumption. Synthetic oil is also an option for your riding lawn mower. SAE 5W-30 is a great all-around alternative to conventional oil.

3. How often should you change oil filter on lawn mower?

Taking proper care of your lawn mower will help your machine run well for years to come. One overlooked aspect in lawn mower maintenance is how frequent oil changes should take place. Engine oil and oil filters should be replaced at least once every spring or summer, or every 50 hours of use - whichever comes first.
