Synthetic or not Synthetic is the Question!!!! Well, first and foremost penzoil is the worst oil for a motor ever made! Castro Synthetic is the worst Synthetic ever since they changed their base stock! The best Synthetics are Mobil 1 or Amsoil! Depending which one you chose, is the one you like! They both are high quality Synthetics!!!! As far as intervals I personal stay at 3000 miles, but with high quality oil filters you can go up to 7500 miles between intervals! I was using Valvoline but switched to Mobil 1. I have had better luck with Mobil 1. Plus is does not break down as fast as Valvoline! Like I said Mobil 1 or Amsoil are the best on the market just depends which one you chose!
