How often do i change the oil on a 2005 che...

change engine oil and filter every 3000 miles.if car is under severe conditions.like. long idling.dusty condition.short running conditions.not letting engine get operating temp.hot climate or temperature.the maintenance intervals said you can change engine oil at 7500 miles.if its not under harsh conditions.

You can go 7,000 miles between changes under normal conditions,if you live in a dusty area or do a lot of stop and go driving 3,000 to 4,500 between changes.

In most cases every 3,000 miles.

changing oil dependent on how you drive or operate a car ---- some sources say every 3000 miles, auto manufacturers actually base it at 5000 to 7000 miles. The best rule of thumb I can suggest is to approach oil changing like washing your hands ---- when it starts looking dirty. for you this could be less than 500 miles if your car is started and stopped frequently or you have a lot of blowby at the piston rings, or it could be as much as 10,000 miles if you are doing hi-way driving-using synthetic oil-using top filter like K&N etc
