Oil Change Frequency and Timing
How Often Should You Get an Oil Change?
The frequency of oil changes depends on several factors:
- For newer GMC models: Every 7,500 to 10,000 miles or once a year, whichever comes first
- For older GMC models or those under severe driving conditions: Every 3,000 to 5,000 miles or every six months
It’s crucial to consult your GMC owner’s manual for specific recommendations, as modern vehicles often have oil life monitoring systems that indicate when an oil change is necessary.
Oil Change by Date or Mileage: Which to Follow?
While mileage is typically the primary factor, time is equally important. Oil can degrade even when a vehicle isn’t driven frequently. Therefore, it’s advisable to change your oil at least once a year, even if you haven’t reached the recommended mileage interval.
How Far Over Can You Go on an Oil Change?
While it’s best to adhere to the recommended oil change intervals, going slightly over won’t immediately damage your engine. However, consistently delaying oil changes can lead to increased engine wear and potential long-term damage. If you’ve exceeded the recommended interval, it’s crucial to schedule an oil change as soon as possible.
Delaying an oil change for an extended period can result in:
- Increased engine wear due to inadequate lubrication
- Reduced fuel efficiency
- Potential engine overheating
- In extreme cases, engine failure
Benefits of Regular Oil Changes
Consistent oil changes offer numerous advantages:
- Improved engine performance and efficiency
- Extended engine life
- Better fuel economy
- Reduced harmful emissions
- Maintenance of warranty requirements
Oil Change Costs
The cost of an oil change can vary depending on the type of oil and your specific GMC model:
- Conventional oil change: $30 – $50
- Synthetic blend oil change: $50 – $70
- Full synthetic oil change: $70 – $100
- Diesel oil change: $80 – $120
While a $100 oil change might seem expensive, it’s important to consider the type of oil and additional services included. Full synthetic oil changes, which are recommended for many modern GMC vehicles, often fall in this price range due to the superior quality and longevity of the oil.
Special Considerations for Gas and Diesel GMCs
Gas Engines
Most GMC vehicles with gas engines can use synthetic oil, which offers better protection and longer intervals between changes. However, always consult your owner’s manual for the recommended oil type.
Diesel Engines
GMC diesel engines, such as those found in some Sierra models, require specific diesel-grade oil. These oils are formulated to handle the higher compression ratios and temperatures of diesel engines. Diesel oil changes may be more expensive but are crucial for maintaining engine health and performance.
Recognizing When Your GMC Needs an Oil Change
While following the recommended schedule is ideal, it’s also important to be aware of signs that your vehicle might need an oil change:
- Oil change or check engine light illuminated on the dashboard
- Dark, dirty oil on the dipstick
- Engine running louder than usual
- Smell of oil inside the vehicle
- Excessive mileage since the last oil change
If you notice any of these signs, it’s advisable to schedule an oil change at our Hammond or Ponchatoula service centers promptly.
