Using the Wrong Oil

When you buy a car from your nearby dealership, the manufacturer distributing the car trim at several geographical locations is aware of the weather conditions of those places.

While changing the engine oil filter, an unprofessional hand might not be able to place the filter correctly.

And if you have used the wrong filter type, the effect of this mistake will reflect sooner or later, when your engine oil will get contaminated in no time and start showing weird reactions.

So, use the recommended type of oil filter, checking out the right size, so that it doesn’t cause a leak.

Other Mistakes

The general methodology of changing the oil and oil filter is tightening bac the entire unit, after the work has been done successfully. You will need the help of some specific tools like the oil wrench to tighten it the right way.

But many times, because of improper pressure, or a hand slip, the O-ring on the oil reservoir can break, causing an improper fitting of the oil seal that will eventually lead to an accidental leak.

So before you shut down the hood, checkout the cap, the O-Ring and other components for a tight and right fit.

Therefore, by losing the track of miles it has travelled since the last oil change can make you change the oil either too soon, or too late and neither of them is good for your car’s engine.

By avoiding these common mistakes while changing your car engine oil, you are strengthening your car and increasing its overall life span.
