Frequently Asked Questions
What is 10W30 oil?
10W30 is a type of motor oil that is commonly used in gasoline-powered engines, including lawn mowers. The “W” stands for “winter”, and the number before it (10 in this case) represents the oil’s viscosity at low temperatures. The number after the “W” (30 in this case) indicates the oil’s viscosity at high temperatures. This means that 10W30 oil is suitable for use in a range of temperatures.
However, it is important to note that not all lawn mowers are created equal. Some lawn mowers may require a specific type of oil, such as a high-detergent oil, due to the design of their engine.
Is 10W30 oil suitable for all lawn mowers?
The short answer is that it may be, but it is not a guarantee. As previously mentioned, the type of oil that is best for your lawn mower will depend on the manufacturer’s recommendations.
