Checking the oil in a Sierra 2500 HD is fairly easy and should be done once a month. Note that most GMC have an oil pressure gauge next to the speedometer - this gauge does not tell you what your oil level is, however the video above will show you how check the oil level in your 2015 GMC Sierra 2500 HD. Make sure your engine is cold when you check the oil in your Sierra 2500 HD. Otherwise the dipstick will read slightly low. In addition to checking the oil level, you also want to look at the condition of the oil when you have the dipstick out. If the oil in your Sierra 2500 HD is dirty or smells like gasoline, you probably need an oil change.
If you notice that the oil level in your Sierra 2500 HD is extremely low or empty, fill it up and check it again the next time you drive. If it is extremely low again, have your mechanic take a look before driving it much more.
If you have an electrical component that doesn't work, try replacing the fuse first
