Not sure what your reasoning is for wanting either if you need to ask. I recommend researching each on a site such as Bob is the oil guy.

You are bound to get responses from people who hate one or the other for whatever reason.

I use Pennzoil Platinum or the German formula Castrol Syntec (now called Edge with Syntec technology...stupid name change IMO). Which ever is on sale. $28-30 oil change > $60+ oil change, especially if you change it at under 5-7k miles.

both are great, amsoil is prolly the better of the two however it is very expensive

Castrol EDGE or Mobil1 EP for the win.

I run RP in my truck and my WS6.
No problem with either and I get better mileage than AMSoil for a lot less bucks.
Pennzoil platinum is good also and I will use it when it's cheaper to buy than RP.

Neither, IMO.

I say just pick a name brand synthetic and you can't go wrong with either of them

Run whatever decent synthetic is on sale and a good oil filter
