Consult your engine operator's manual for information specific to your engine. Proper care and maintenance of your equipment is proven to be the key to long engine life. Prior to each engine start, always check the oil dipstick for proper oil level. If you have new equipment or a new engine, oil typically does not come already added.
Do not use special additives. Outdoor temperatures determine the proper oil viscosity for the engine. Use the chart to select the best viscosity for the outdoor temperature range expected. Engines on most outdoor power equipment operate well with 5W30 Synthetic oil. For equipment operated in hot temperatures, Vanguard 15W50 Synthetic oil provides the best protection. Check oil level more frequently.
The Society of Automotive Engineers has developed a categorization of motor oils which will indicate the viscosity thickness and temperature in which engine oil can be used. This is called the SAE, it is printed on every bottle of oil and will also indicate whether or not the oil is synthetic.
Above is a chart that lists SAE type and the temperature in which it functions the best. We have recently modified our engine oil recommendations to state that you may now use a synthetic 5W30 or 10W30 oil in all temperature ranges.
Engine break-in procedures using synthetic oil remain the same. Please keep in mind that the use of synthetic oil does not preclude you from performing your regularly scheduled lawn mower maintenance i.
Engine oil capacity is, just like oil type, dependent on your specific engine model. Learn how to properly and safely use, troubleshoot, and maintain your lawn mower, tractor, snow blower, and other lawn and garden equipment. View How-To Articles. The main difference between the two types of engines is that a four-cycle engine requires two revolutions of the crankshaft and piston to draw the fuel and air into the cylinder, ignite it, then exhaust the combustion gases, whereas a two-cycle engine requires just one revolution to do the same thing.
Another crucial difference between the two engine types is how the oil should be added. A four-cycle engine draws gasoline from a fuel tank and has a separate sump to supply the necessary oil. A two-cycle engine requires the gasoline to be mixed with the oil for the engine to operate properly.
This can be tricky since attempting to run a two-cycle engine without a suitable oil and gas mix will cause the engine to seize due to insufficient lubrication. By having a separate sump for oil, a four-cycle lawn mower engine needs to be maintained in a similar fashion to a car engine, meaning the oil should be changed regularly.
How often you change the oil is dependent on how often you use the lawn mower. While the procedure for replacing the oil will differ depending on the type of mower you have and the engine model, for most walk-behind mowers, you can usually unthread the oil tank cap , remove the dipstick, if applicable, and carefully tip the mower to empty the old oil into an approved container.

Prior to each engine start, always check the oil dipstick for proper oil level. If you have new equipment or a new engine, oil typically does not come already added. Now you know what type and how much oil you need. Watch this video to learn how to do a small engine oil change. If you're using equipment with a 2-cycle engine make sure you're mixing the correct oil and gas ratio.
