What kind of oil do you put in a 2001 Mazda 626 full synthetic or regular oil?
It is recommended to use full synthetic oil in a 2001 Mazda 626. Full synthetic oil is more stable at higher temperatures and does not break down as quickly as conventional oil, which can help extend the life of the engine. Additionally, synthetic oil can provide better lubrication, which can help reduce wear and tear on the engine components. The SAE grade of the synthetic oil should be selected according to the manufacturer's recommendations. Generally, a SAE grade of 5W-30 or 10W-30 is recommended for the 2001 Mazda 626.
