Factors to Consider Before Buying Oil for Kohler Engine
If you are in the market for ideal Kohler engine oil, there are factors to consider. Here are a few of them:
One of the crucial aspects of the engine is its viscosity. In clear terms, viscosity is the resistance of flow in any sort of liquid. The thicker the oil, the more viscous it is.
For instance, in 5W-30 engine oils, the “number 5” signifies the maximum viscosity of the oil at low temperatures. The lower the number, the more it would perform at lower temperatures.
As for Kohler engines, we suggest that you get an oil that has 10W-30 viscosity. They operate efficiently on Kohler engines such as Aegis, CS, Courage, Command, and Command Pro engines.
Another factor to consider before buying engine oil for your Kohler engine is temperature. If you have a K-Series or Magnum engine, you can make use of the SAE-30W oil because it works well on Kohler engines at a temperature above 32 F.
If the temperature is higher than 50 F, you can also use SAE 30 for non-K series engines
Amount of Oil
The amount of oil you would need depends on how long the engine runs. Most Kohler engines need 1-3 quarts of oil, so, you need to get enough oil so that you can re-use the oils each time it runs out.
Types of Oils
It is advisable to know the oil types available on the market before buying. Some are pure oils while some are a blend. For optimal performance, it is better to get synthetic oil for your Kohler engine.
How Does Temperature Affect the Viscosity of Oil?
The viscosity of the oil and the temperature have an inverse relationship. If your oil has a lower viscosity, it will flow easily but if it is higher, the engine oil will be thicker, enabling it to flow less.
This process allows this viscosity to change with the temperature. An increase in temperature will make its viscosity decrease and vice versa.
Frequently Asked Questions
What happens if you don’t change the oil in the Kohler engine?
If you don’t change the oil in your Kohler engine, it will get dirty, causing the engine to wear out.
Is synthetic oil good for Kohler engines?
Yes, synthetic oil works well on Kohler engines. Synthetic oil enables better viscosity and deposit control. It also provides better wear and low-temperature fluidity.
