It all depends what API level is Honda oil? If it is API SG then easily you can use it for 5,000 Kms. If it is API SJ then you can run upto 8,000 Kms. If its API SL then can run upto 12,000 Kms and if API SM then can go for 15,000. But oil should be genuine and secondly oil filter should also be genuine. Oil filter must be changed @ 10,000 Kms at most.
I am using Castrol Magnetic in my Cultus 2007 and that is API SL. I am planning to change it on 15,000 and it has done so far 12,000. But I have changed the oil filter @ 10,000 Kms. In Saudi Arabia there comes FUCHS Super Syn API SL and that can easily run upto 20,000 Kms even Mobil 1 can run upto 15,000 to 18,000 Kms.
