Engine Oil Change – Intervals For Synthetics & Non Synthetics

Engine Oil Change is crucial because there are a lot of additives in the oil that become dirty and essentially wear out causing the lubricating properties that protect the engine to diminish. This results in some metal parts to be eaten away and water being retained in the crankcase which results in sludge.

The sludge mixture will just keep building up by attracting more abrasive particles and then wear down the engine instead of protecting it like clean oil does.

This is why changing your oil at specified intervals and more frequently than the manufactures recommendations if you drive less frequent or in abnormal conditions like stop start traffic is so important.

Engine oil change Replaces:

  • detergents
  • dispersant additives
  • viscosity additives
  • anti scuff or friction modifiers
  • corrosion inhibitors

If your vehicle is used a lot for short trips and doesn’t reach operating temperature often before you turn the engine off then it is advisable to change the oil more frequently than what the manufacturer recommends to get the most out of your engine.

For general driving of the vehicle every 5000 kilometers is a good rule of thumb before you really need to change the engine oil.

Non Synthetic Engine Oil Change Interval

For older cars using non synthetics, say no more than every 5000 kilometers.

Synthetic Engine Oil Change Interval

With more advanced engine design and better oil formulations like fully synthetics, manufacturers are always increasing the oil-change intervals. It is still highly recommended to check the oil yourself frequently and have it changed more frequently too. With newer cars say no more than every 8000 kilometers or so just to be on the safe side.
