The best way to think of your engines oil is that it is your engine’s life blood. Without oil your engine would stop running. The oil travels throughout all parts of the engine and lubricates all of the components to run properly, a good rule of thumb is that the cleaner your oil is, the better your engine will run.
Oil in your lawn mower needs to be changed every 20-50 hours, and you should check your owner’s manual to see which oil type you should use, but if you have been to the store to buy oil, you know there are tons of different kinds, so what the difference?
It is important to understand what all of the different oils are. When shopping for oil you probably noticed a bunch of different numbers and letters on the bottles without much explanation of what they mean. The Society of Automotive Engineers (SAE) developed a way to categorize oil based on their viscosity. It is easiest to think of viscosity as the liquids “thickness”, think water versus syrup.
For example, we will use SAE-5W-30. The higher the initial number of the oil, the thicker it is, 0 is like water and 10 is like syrup. The W stands for winter, meaning that is the viscosity of the oil in cold temperatures. The last number, in this case’30’, represents how well the oil flows after being heated to 212° degrees Fahrenheit. 0W-30, 5W-30, and 10W-30 all perform the same when heated up to 212° degrees Fahrenheit, but at lower temperatures the 0W-30 is the least viscous, and 10W-30 is the most viscous.
So what does all of this mean for you? Basically, just that you have to know the environment that you will be working in. if you are working in colder temperatures, 5W-30 may help you start your engine easier, but it will us more oil in higher temperatures. If your mower will get prolonged use in a commercial setting, then it is best to use a 15W-50 oil.
