I just Bought my 06 mazda 6i about 5 months ago i started to hear some kocking coming from the engine compartment at 9k miles so i took the car in, they said that it was lower engine knocking and it was caused by my lack of chainging the oil, now i know it should have been done at 7500 but i figured it would be ok and i was very busy so i held off a little, anyways they say they wont fix it under my warranty and it will need a new engine. I was wondering if there was anything i could do and if it really was my fault or a faulty engine???

They should cover it-this time, BUT you are responsible to do the oil changes at the proper times. NOT when you have time, there is no reason why you can have you oil changes done on time (OR early! OH my GOD!)

If you've been neglectin the oil changes, the knocking is probably due to worn out engine bearings which is very bad news.

Suggested Repair

Neglected oil changes likely caused lower-engine bearing wear and knocking, so a new engine may be required. Ask the dealer to cover the repair this time, and perform all future oil changes on schedule or early.

Conversation Summary

The owner of a 2006 Mazda 6 heard engine knocking around 9,000 miles after delaying an oil change. The shop diagnosed lower-engine knock from missed oil service, denied warranty coverage, and said a new engine was needed. A Mazda technician said the dealer should cover it this time but that oil changes must be done on schedule. Another expert said neglected oil changes likely wore the engine bearings.
