A Guide to Routine Maintenance at Frank's GMC
Keeping track of your vehicle’s maintenance schedule can feel like a guessing game, but staying proactive is the absolute best way to save money and keep your vehicle safe. Here at Frank's GMC in Lyndhurst, NJ, we believe in straightforward, transparent service. Whether you use your Sierra for heavy towing or rely on your Acadia for family road trips, here is a practical guide on when to bring your vehicle into the shop.
1. Oil Changes: The Lifeblood of Your Engine
Oil lubricates the moving parts in your engine, prevents overheating, and sweeps away dirt. If you wait too long between changes, the oil breaks down into a thick sludge that causes extreme friction and eventual engine failure.
- Modern Synthetic Oil: Most newer GMC vehicles run on synthetic oil and feature an in-dash Oil Life Monitoring System. Generally, you should plan for a synthetic oil change every 5,000 to 7,500 miles.
- Conventional Oil: If you are driving an older model that uses conventional oil, the standard rule of thumb remains every 3,000 to 5,000 miles.
- Severe Driving Conditions: Stop-and-go traffic, towing heavy loads, and extreme winter weather put extra strain on your engine. Under these conditions, err on the side of caution and change your oil closer to the 5,000-mile mark.
2. Tire Care: Safety From the Ground Up
Your tires dictate your braking distance, fuel economy, and handling. Ignoring them is not just expensive—it is a major safety hazard.
- Rotations: You should rotate your tires every 5,000 to 7,500 miles. Doing this at the same time as your oil change is a great way to stay on track. Rotation ensures the tread wears evenly across all four tires, extending the life of the entire set.
- Air Pressure: Check your tire pressure once a month. Under-inflated tires run hot and are prone to blowouts, while over-inflated tires wear out the center tread and result in a harsh ride.
- Replacement: Start shopping for new tires when the tread depth reaches 4/32 of an inch. If your tread is down to 2/32 of an inch, your vehicle is unsafe to drive, especially in rain or snow.
3. The Big Stuff: Major Milestones
Beyond the routine basics, your vehicle requires more comprehensive servicing at specific mileage intervals.
- Brakes (30,000 - 50,000 miles): Brake pad lifespan depends heavily on your driving habits. If you hear a high-pitched squeal or feel a vibration in the steering wheel when stopping, it is time for new pads and a rotor inspection.
- Transmission Service (45,000 miles): Transmission fluid degrades over time and needs to be flushed and replaced to ensure smooth shifting and prevent catastrophic gear damage.
- Timing Chains and Belts (80,000 - 100,000+ miles): While many modern GMC engines utilize highly durable timing chains rather than belts, they still require professional inspection. Tensioners and guides can wear out as you approach the 100,000-mile mark, and failure here can ruin an engine.
- 4x4 Service (50,000 miles): Front, rear and transfer case service is recommended
- Tune-Up (90,000 – 100,000 miles): This is a service that can include replacement of spark plugs, wires, and a coolant flush.
Never wait for a dashboard light to tell you something is wrong. Staying ahead of your maintenance schedule keeps your truck or SUV running exactly the way it was engineered to.
