Question:
I'm really confused about auto service intervals for various items on my car. Help!

Graf's Automotive Answer:
The simple answer for Astoria residents is to follow the vehicle's recommended service intervals listed in your owner's manual or in your service center's database. But the team at Graf's Automotive in Astoria sympathizes with Astoria residents because of the confusing intervals for modern vehicles.

The days of simple rules of thumb that applied to most vehicles are long gone. For example, let's look at an oil change: manufacturers' recommendations run anywhere from every 3,000 miles (5,000 kilometers) to 15,000 miles (24,000 kilometers). This big range comes from engine design and recommended types of oil - so Astoria residents really do need to read and follow the recommendations for their specific vehicle.

Your owner's service manual will have a schedule for maintenance services and inspections.

Service items include:
Tire rotation, wheel balancing, oil change, coolant service, transmission service, brake system, power steering system, fuel system, differential service and transfer case service.

Inspections will include:
Alignment check, air conditioning, brakes, suspension, axles, exhaust, tires, lights emissions, belts and hoses and steering.

It's for Astoria residents to remember there is no exception that would make it OK to extend an interval. These intervals already assume "best case" conditions for a safe margin of error. However, you may live or drive in Astoria conditions that are harsher than average. Your owner's manual may have a modified schedule for “severe service" - things like extreme OR temperatures, towing, hauling heavy loads around , short trips, stop-and-go conditions, etc.

Consult your owner's manual or talk with your Graf's Automotive service advisor about your driving situation and adjust your service intervals accordingly.
