How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
SAE 10W-30 4-Cycle Lawn Mower Oil (20 oz)
Use Briggs & Stratton SAE 30W Oil above 40°F (4°C) for all of our engines. Check oil level regularly.
The Full-Synthetic SAE 5W-30 SN Motor Oil is designed for 4-Cycle lawn mowers and snow blower engines.

Can you use 5W-30 instead of 10W-30? Absolutely yes for car engines, 5W-30 is usually synthetic and superior to 10W-30. Both have the same viscosity at the operating temperature of an average car engine. 5W has lower viscosity when cool and is considered better for the car engine during engine start.
Is SAE 30 Oil The Same As 10W-30? No. Unlike SAE 30, SAE 10W-30 is multi grade oil. SAE 10W-30 has SAE 10W viscosity at a lower temperature and SAE 30 viscosity at a hotter operating temp.
There`s not much difference between 10W-30 and 10W-40 motor oil. What sets them apart has more to do with temperature fluctuations and engine load. For moderate weather, either engine oil grades should work fine.
The oil you use for your car`s engine is the same one you can use for your lawn mower. However, make sure that your motor oil is of high quality before using it in a lawn mower engine, which is comparably smaller and less hardy. The quickest way to shorten the life of your lawn mower is to use low-quality engine oil.
SAE-30 oil is often a safe bet for your mower, but it`s still worth referring to your owner`s manual since a lawnmower is no small investment. Since you won`t be mowing in the wintertime unless you have a landscaping emergency in colder temperatures, there`s no reason to use a multi-grade motor oil such as 5W-30.
Car oil is similar to lawn mower oil, and you can use it in lawn mowers with four-stroke engines. However, car oil has a high concentration of additives and can damage smaller engines. It`s also important to match base oils; otherwise, you risk damaging your lawn mower`s motor.
The main differences between SAE 30 and 5W30 are that the SAE 30 is a single-grade type, that can be used for small engines, and would generate in warm weather. On the other hand, 5W30 is a multiple-grade type, that can be used for larger engines, tolerating extreme weather.
There is no difference between 4-cycle oil and regular engine oil; they are the same. Common engine oils used in lawnmowers are SAE30, 5W30, and 10W30. A lawnmower engine will start without oil, but you must never do so; even running it for a short time will cause serious engine damage.
Oil capacity is typically 15oz or 18oz*. Check oil level during the season and add when necessary. Change engine oil every 50 hours or annually, whichever comes first.
