In addition, it lubes them to avoid friction and protection against wear and tear. While in most cases, poor oil won’t contain many additives that cause countless mechanical issues.
  • Quality oil keeps your engine clean from sludge and deposit formation, which helps you change the oil. But the poor oil produces lots of deposits that make the engine parts gooey and sticky. 
  • While the Kawasaki lawn mower engine makes lower emissions for quality oil, the same engine makes too much emission for poor oil. 
  • The engine will offer high RPM speed, consume less fuel, and ensure fuel efficiency when you use the right oil as its food. Unfortunately, poor oil will be consumed with no fuel efficiency.  
  • The quality oil will help the engine to cool down after facing lots of stress and pressure due to harsh weather conditions. But, on the other hand, poor oil will overheat the engine, which leads to seizing the engine and destroying it forever. So you have no option to replace the engine, which is very expensive. 
  • One thing is, in some cases, the poor oil is slightly less expensive than quality oil. But in the long run, using poor oil consequences is horrible.
