Every driver asks it: when should I change my engine oil? The answer depends on the oil type and your driving conditions — and the golden rule is always: follow the manufacturer's manual first.

General Guidelines by Oil Type

  • Mineral oil: Typically every ~5,000 km
  • Semi-synthetic: Typically every ~7,500 km
  • Full synthetic: Typically every ~10,000–15,000 km

These are guidance figures — your owner's manual is always the most accurate reference.

Severe Conditions Mean Changing Sooner

The following conditions accelerate oil degradation and require shorter intervals:

  • Frequent stop-start city driving
  • Extreme heat (very common in Syria during summer)
  • Dusty roads
  • Frequent short trips where the engine never fully warms up

Warning Signs That Mean Change Now

  • Oil looks very dark or has a thick, sludgy consistency
  • Engine sounds louder than usual
  • Oil warning light illuminates
  • A long time has passed since the last change, even if km haven't been reached

Don't Forget the Filter

It's best practice to replace the oil filter with every oil change — this ensures truly clean oil circulates and your engine components are fully protected.

Bottom Line

Don't wait for problems to appear. Changing your oil on time is the simplest and cheapest investment in engine longevity. Choose the right ALHAZEM oil for your vehicle and driving conditions.
