KEEP IN MIND THE OIL VISCOSITY

The most crucial feature you need to pay close attention to while choosing the engine oil is its viscosity. You can find the recommended type of oil in the Owner´s Guide or Manual.

In most cases, you will need an SAE 10W-30 oil type. The 10W-30 oil from Honda (1,767+ Reviews) is the best one in this category, but it’s pricey. We think that it is the best fit for most engines. 

Here is our detailed comparison of 10W-30 oil vs 5W-30 oil, the second most recommended type of oil for PREDATOR engines.

For cheaper alternatives, check out Valvoline VR1 Racing (725+ Reviews) or Castrol Motor Oil (465+ Reviews). They offer the same performance for a better price.

The SAE acronym in the name of motor oil refers to the grading system developed by the Society of Automotive Engineers. The rest of the code refers to the oil’s viscosity at different temperatures.

The first number in the code, in this case the 10W, means how well can this oil be pumped at cold temperatures. The W refers to the word winter (not the weight). 

The second number in the code means how well can the oil be pumped when heated to 212 degrees Fahrenheit (100 degrees Celsius) or higher.

Also, you should select a good quality detergent oil bearing the American Petroleum Institute (API) service classifications SJ, SL, SM, or SN.

Bear in mind this fact: If you use a different type of oil than the recommended one, you may cause premature wearing of individual engine parts.

THE IDEAL OIL CHANGE FREQUENCY

The main idea for changing the oil at regular intervals is to make your engine last as long as possible and avoid unnecessary damage.

The general rule is to change the oil after the first 20-30 hours of operation and every 100 hours of run time thereafter. With synthetic oil, you can double the run time to 200 hours.

To sum up the ideal oil change frequency:

  • The break-in oil change is at 20 hours
  • Monthly / 20 hrs. of use
  • Every 6 months of use
  • Every 100 hours of use

When you are not sure of the ideal interval, just remember this: You can’t go wrong with changing the oil sooner rather than later.
