I just bought a new Kia Amanti. The dealer recommends oil changes every 3,000 miles but the service book shows Kia only wanting it done every 7,500 miles. I know 3,000 is the old stand by but the difference is pretty big. Anyone have any thoughts on this?

Thanks,

3k miles was created more by shops than it ever was based on manufacturers requirements which can vary greatly from model to model.
the important thing is atleast to change your oil as often as required by the manufacturer changing at 3000 miles instead of 7500 does not necasarily mean you will have longer engine life but does usually keep internal engine deposits down to a minimum.
