While reading the above posts, I was wondering if the car running is not that much do you still need to change the oil every 3 months?. In my case time would come earlier, as I had put in Shell Helix Ultra which gives a maximum change interval of 5,000 kms but my daily running is very low about 20kms. So I have just completed 4,970 kms after about 8 months. If I were to change my oil after 3 months I would have only done about 1,500 kms. So what do I do in my case????? :S
