Pennzoil Platinum is one of the leading synthetics oils on Http://bobistheoilguy.com with the oil analysis to back it up.
No I don't use Pennzoil. I use German Castrol Syntec the European formula 0W30 a true Group 4 synthetic Only available at Autozone.

I ran royal purple in my truck for 50,000 miles but then it got way to expensive so i did the switch to Castrol Edge and honestly I think it works much better and also it is much cheaper. I will be sticking to Castrol for a while but i might just go and give mobil 1 a try aswell.
