7 Signs Your GMC Needs an Oil Change

Getting an oil change is a quick procedure that needs to be done once or twice a year. You’ll find your vehicle’s recommended oil change interval in the owner’s manual. Sticking to this schedule is a great way to prevent issues, but your car may let you know you need an oil change before your next scheduled one. Let’s look at some signs that you need one.

7 Signs You Need a GMC Oil Change

1. You Have Dark Exhaust Smoke

Exhaust fumes should be transparent, but they could darken when there’s an issue with your car. It can tell you that you need an oil leak, so it’s time to visit the dealer for a repair and fresh oil.

2. Your Oil Looks Dirty

Checking your oil manually should be part of your routine even though modern vehicles have oil life monitors. Pay attention to the color and consistency of the oil when you check it. If it’s dark and thick, then you need an oil change promptly. If it gets too thick, then it could clog your engine instead of lubricating it.

3. You Smell Burned Oil

Smelling burned oil can tell you the oil is dirty and old, so it needs to be changed ASAP. Even a general burning smell that doesn’t smell specifically like burning oil can tell you it’s time for some fresh oil.

4. Your Fuel Economy Is Worsening

Your fuel economy may get worse any time your car is under pressure. Having low-quality oil or a low oil level can strain the engine, leading to reduced fuel economy. An oil leak can also reduce your fuel economy.

5. You Hear Loud Sounds

Cars often make strange noises when there’s a problem with them. Hearing an increase in engine noise, rattling sounds, or other unusual sounds coming from under the hood can all tell you the oil level is low or the oil is low quality.

6. Your Engine Gets Too Hot

A car’s engine can overheat when the parts of it aren’t lubricated enough. Old and poor-quality oil can’t lubricate the engine very well, leading to friction that makes the engine overheat. If your temperature gauge starts climbing or you see steam coming out from under the hood, then it’s time to pull over and let the engine cool down before it gets damaged.

7. You Can’t Switch Gears Easily

Having trouble shifting gears usually tells you that there’s a problem with your transmission, but it can also tell you that you need an oil change. This is because a clogged oil filter can also make it harder to shift gears, and this filter is typically changed during a regular oil change.
