I have 5AFE engine in my corolla and i'm using 20W-50 oil .
After around 3000Km its start to burn engine oil ( castr') . For every 5000 Km i had to use 4.5-5 liters of engine .
I'm worried little about this . Is there any problem ?
And major case is to inside of the car engine noise is little more than normal .for outside its not that much . I can feel the vibration of the car . Its not much like a diesel car .
Some say this may be hard engine mounts ( its has not OEM engine mounts ) .
Any tips to correct/find the faults .
