Of course your vehicle may be new enough to get away with a synthetic oil. Synthetic can sometimes protect better, but synthetic oils are very thin. I had an 87 Wrangler that I used synthetic oil in and I found all kinds of new oil leeks with it

After some new seals, I never went lower than 10W40 again.

I use Valvoline Max Life 20w50 in my 318 with 119k miles. If you have higher mileage run either Maxlife or Castrol GTX high mileage oil. These new "high mileage" oils seem to be becoming popular but Valvoline was first so i tend to think theirs might be best at least for now.

I'm very happy and satisfied with the Valvoline 10W30. As previously stated by Tick, if your vehicle has low millage you might consider synthetic, but I would probably shy away from useing that on something that has over say 85,000 miles.

Make sure you use a good oil filter as well which isn't always going to be the most expensive brand out there.
