How to Use the Oil Capacity Chart
- Identify Your Engine Model – Check the engine code on the side of your Kawasaki engine (e.g., FR691V). This is more accurate than relying on mower deck size or year alone.
- Match the Engine Code to the Chart – Find the correct row above to know how much oil your engine holds.
- Refill Carefully – Add about 90% of the listed capacity first, run the engine briefly, then check the dipstick and top off to the “FULL” mark.
- Change the Filter with Every Oil Change – The listed capacities assume a fresh filter unless noted.
