How To Change Oil On A Kawasaki FR651V?

Changing engine oil on FR651V is pretty much the same as other Kawasaki engines. However, in this section, we will be showing how you can change the engine oil on Kawasaki FR651V but before that, there is something vital we must make you aware of. 

It is no secret that gasoline is highly flammable and if not treated right, things can go south. So before you start changing oil, here are a few things you should take care of. 

Make sure the engine switch is off. Pick a well-ventilated area and make sure the area is free from things that might cause sparks or anything like that. 

Once you take care of those, now you can proceed further. Here’s how you should change the engine oil on your Kawasaki FR651V engine. 

  • Warm the engine a bit, and then pick a level surface to place the engine there.
  • Pick an oil drain pan, and place that under the drain plug. 
  • Remove the drain plug and let the oil drain. 
  • When all the old oil is drained, attach the drain plug and secure that properly. 
  • Locate the oil gauge and thoroughly clean the area around the gauge if it’s dirty. Even if it doesn’t look dirty, wipe the area with a dry cloth. 
  • Remove the oil gauge and clean that with a cloth. 
  • Take the engine oil and slowly pour the oil into the oil tube. 
  • If you look closely, you’ll see a “Full” mark. Under no circumstances the oil level should cross that. 
  • Once you think you have poured enough, then put the oil gauge into the tube and check the oil level. The oil level should be between the “Fill” and “Add” marks. 
  • When the level is fine, put the oil gauge back and screw it tightly.
