Should i change the the oil after one year but only 3000 new miles

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! With your 2014 ML350, it's generally a good idea to change the oil at least once a year, regardless of mileage. Even if you've only driven 3,000 miles in 13 months, oil can break down over time due to contaminants, moisture, and heat. Since it's been a year, I recommend going ahead with the oil change. If you're also due for a Service A (which typically includes an oil change, oil filter replacement, and inspection of various components), this would be a perfect time to get that done. Keeping up with your service schedule helps maintain your vehicle’s performance and longevity.
