Most experts agree that the main benefit of using synthetic oil is the convenience of longer oil change intervals. While conventional non-synthetic oil is recommended to be changed every 3,000 miles, you can typically go 5,000 7,500+ miles on synthetic without worry. And though synthetic is much more expensive, it's worth the extra cost for drivers that dont want to change their oil as frequently. When shopping for oil, it's hard to go wrong if you use a brand approved by the manufacturer and the correct viscosity. Our picks for the best synthetic oil show consistent performance over long drains.

Pennzoil Platinum performs well, is easy to find at retail locations, and costs much less than boutique synthetic oils such as Redline or Amsoil. You can pick up a 5 liter jug for around $20 from Walmart, making it an excellent value.

Factoring in a combination of performance, availability and value, this is the best overall synthetic oil for most drivers.
Widely considered to be the best synthetic oil money can buy, AMSOIL would be the #1 choice if it weren't for its high price tag (nearly double that of Pennzoil Platinum) and the fact that it's harder to find unless you're ordering online. AMSOIL synthetic oil can withstand extreme temperatures and holds up very well under extended drain intervals. If you want the best and don't mind paying for it, it's the way to go. Read Full Review

Mobil 1 synthetic oil offers great performance and is readily available in retail stores and online, but typically costs a bit more than Pennzoil Platinum and doesn't offer much to justify the higher cost.
