When to change engine oil

[aamirqayyum1]

Hi Everyone,
I recently purchased Cultus 2010 80k milage after the purchase i changed the engine oil shell helix hx6 10W-40 synthetic technology motor oil. I want to know when should i change the oil at 3500KM or 5000KM

On PakWheels it Says that synthetic should be changed at 5-7000.

Thanks for your answers.

I am using the same oil in my 08 model...and change it every 5/6k km

Hx6 is semi synthetic...dont go over 5000kms in any case

5000 is good enough.
Check oil level on weekly or monthly basis which one is easier.

[aliaamir0335]

strictly 5000km

I would say; 5,000 Kms.

3-3,500 Kms would be waste of money and resources IMO, and 6-8,000 Kms may be bad for engine as engine oil might have severely deteriorated.

Change it between 4500-5000. Don't over run.

Strictly 5000 kM is correct. After that your engine itself shows low pickup, heavy sound, low mileage etc....
