When changing the oil go by mileage (3k)
The time rule 4 months is for cars that are driven little.
Whatever you do. Don’t use the likes of Jiffy Lube. They aren’t necessarily equipped for or aware of the possible specific needs of your car.
(An example) Honda uses a soft aluminum washer as a gasket for the oil drain plug. It cannot be reused. JL does not have these and will overtighten the plug to try to make a proper seal. Just one overtightening can strip the threads in the oil drain hole and ruin the entire oil pan.
Also, an oil change in an opportunity to have a technician (not an oil change hack) have a look over the bottom of the car for problems. Problems that can be resolved before they worsen.
To get your business most dealershps now charge little more than JL and use parts specific to your vehicle.
Finally, repeated oil changes is a cheap way to develop a good relationship with a service department. The more business you give them the more breaks they’ll cut you when they can.
