The 2011 Acura MDX oil type and capacity iS5w-20 and 4.5 quarts. Having high quality oil is important for the engine to run smoothly. You will run into problems with the oil at some point. Old or bad oil can cause the engine to stop working. Knocking noise may come about from the engine. You could experience terrible gas mileage. A common problem is an awful burning odor. This needs to be viewed closely as soon as possible or the car might explode. Your oil needs to be changed out someday. Every 5,000 to 10,000 miles or so is a good rule of thumb. If You don't replace it, there will be problems with the engine.

The approved oil type for the 2011 Acura MDX is the SAE 5W-20 displaying the API Certification Seal. The engine oil capacity for the 2011 Acura MDX is 4.5 US quarts (4.3 liters).
This really depends on the mileage of the vehicle (not just for the 2011 Acura MDX) the longer an engine runs, the more space you get between seals, gaskets and metal moving parts, and the more oil you will burn through. So, even though the owner's manual calls for SAE5w20, a 10+ year-old vehicle will burn through that faster than 10w30.
