I only do my first oil change at 5k after that 7500k easy if its synthetic I go longer, big decider is how the oil looks etc. Alot of the dealers do the 3k/4 months because they want to "train" the purchaser to come in to get it changed more frequently so they make more money. By saying to do it in 4 month intervals instead of 6 they are getting double the money out of the person every year in oil changes.
