How many quarts of oil does a 2018 GMC Canyon take?
The 2018 GMC Canyon requires exactly 6 US quarts (5.7 liters) of engine oil when replacing both the oil and filter.
What viscosity oil does the GMC Canyon use?
The manufacturer specifies 0W-20 dexos1 Gen 3 for all ambient temperature operating ranges.
What size socket is needed for the oil drain plug?
The oil pan drain bolt requires a 15mm socket, torqued to 18 ft-lbs (24 Nm).
How often should you change the oil on a 2018 GMC Canyon?
Under normal driving conditions, replace the oil every 7,500 to 10,000 miles (or 12 months). Under severe conditions (short trips, heavy stop-and-go driving), change oil every 5,000 miles (6 months).
Do you need to replace the crush washer on each oil change?
Yes. The aluminum crush washer deforms to create a liquid-tight seal against the oil pan. Reusing an old crush washer can cause oil leaks and stripped oil pan threads.
