Buying Guide

Choosing good motor oil helps engines. It keeps your car going.

Many people like these oils. They say their cars run better and they do not need oil changes as often.

Here’s how to pick the best oil:

  • Viscosity: Oil thickness matters. Use what your car manual suggests. Select 0W-20 for cold weather or 10W-30 for warmer climates.
  • Synthetic vs. Conventional: Choose synthetic for best wear protection. But if your car is older, conventional oils may be very fine. Synthetic lasts long, but costs more.
  • API Rating: Look for the API donut on the oil bottle. It shows if the oil meets required standards. Choose oils labeled with API SP or higher for good results.
  • Mileage Considerations: If your car goes far, grab high-mileage oil. They keep older engines in great working order. These oils stop drips and get rid of sludge.
  • Engine Type: Motorcycles need special oil. Look for oils marked JASO MA or MA2. This oil is safe for wet clutches.
  • Brand Reputation: Big brands may be very good. Trusted companies like Valvoline and Castrol made the oil. Read opinions to learn what may work.
  • Additives: Some oils have additives to lower wear. Other oils add detergents that keep your motor clean. Check to see what special ingredients they have.
  • Price and Quantity: Oils change in price. Know how much oil you need. Five quarts might be a money saver.
