Editor's Pick: If you change your own oil, you're probably familiar with Quaker State. This full synthetic oil has a solid reputation for cleaning engine carbon deposits, and you won't notice much performance drop even after a few thousand miles. It's a good idea to keep a bottle on hand for regular maintenance, and at this price, stocking up a few is a smart move. Just note that different viscosities are suitable for different vehicles, so check your car's recommended grade before buying.
