There is a change engine oil light. It depends on the type of mileage you drive. The light will come on when the oil begins to break down. I'm running synthetic in mine and it usually last me 7500 to 8000 miles. Keep in mind also, this engine hold 7 quarts of oil. It will not break down as quickly as your engine that only holds 4 quarts... No Need to change every 3000 miles!
