Mobil 1 Advanced Full Synthetic 5W-20 is a full synthetic engine oil sold here as a four-quart pack of one-quart bottles. It is built on Mobil 1's Triple Action formula for performance, protection and cleanliness, and the maker claims protection for up to 15,000 miles between changes and strong sludge control. It meets ILSAC GF-7 and carries OEM approvals, and it is also rated for diesel engines. Against conventional oils and store-brand synthetics it offers a longer drain interval and better cold-start flow; against Mobil 1 Extended Performance or European-formula oils it is the mainstream pick rather than the longest-life one. Owners of cars specifying 5W-20, including many Ford, Honda and Toyota engines, use it as a routine oil-change oil.
