Inquire about the oil variety and volume needed for a 2003 Acura MDX.

Every 2003 Acura MDX is equipped with the same 3.5L V6 engine, which requires approximately 4.2 quarts of SAE 5W-20 full synthetic motor oil without a filter change (or 4.5 quarts with a filter change). While Acura suggests the use of SAE 0W-20 full synthetic oil as an alternative, the performance difference in the MDX's J35A5 engine between the two options is minimal. In case neither is available, a temporary solution may be to use SAE 5W-30, but it is not advised, and oil change is necessary promptly. Thicker oil can cause excess friction in the engine, potentially leading to premature wear and damage to engine parts, resulting in early engine failure. Thus, it is best to opt for SAE 5W-20 or SAE 0W-20 whenever possible, even if it comes at a higher price. In the long term, you will appreciate this decision.
