The 2001 Subaru Forester useS4.2 quarts of SAE 5W-30 oil. Subaru recommends that You use synthetic oil whenever You need to change it in Your car. The two main types of oil that You will encounter these days are synthetic and conventional. Synthetic is a newer type of oil that is engineered in a lab to give You greater wear protection and longer life than the petroleum-based conventional option. This means Your engine stays protected for longer and You need less frequent oil changes as well which can save money in the long run. You should check Your oil at least once a month to make sure that it is full and free from any debris or signs of burning.
