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.

HOW TO CHANGE OIL IN YOUR PREDATOR ENGINE

Changing the oil in your Predator engine involves the following steps:

  1. First, you need to locate the oil drain plug. It is located on the bottom of the engine near the oil filler cap.
  2. Place an oil pan or container underneath the oil drain plug to catch the used oil.
  3. Remove the oil drain plug by using a socket wrench or an adjustable wrench. Make sure you loosen it enough to allow the oil to drain completely, but don’t remove it all the way yet.
  4. Wait for the used oil to drain out completely into the oil pan. This may take a few minutes, depending on the amount of oil in the engine.
  5. Once the oil has drained out completely, replace the oil drain plug and tighten it securely.
  6. Remove the oil filler cap from the top of the engine and pour the recommended amount of fresh oil into the engine. You can find the recommended oil type and quantity in the owner’s manual or on the engine itself.
  7. Replace the oil filler cap and start the engine. Let it run for a few minutes to circulate the fresh oil throughout the engine.
  8. After running the engine for a few minutes, turn it off and check the oil level using the dipstick. If necessary, add more oil until the level reaches the appropriate level.
  9. Finally, dispose of the used oil in an environmentally friendly way. You can take it to a recycling center or an auto parts store that accepts used oil.
