Remember, it is almost impossible for anyone, myself included, to diagnose a problem over the internet without seeing the car. My advice is simply that, advice based on years of experience. I don't want you or anyone taking my word as gospel. I am trying to give some direction as to what I think may be happening.
I personally heard alot of good things about the Castrol Syntec thats what I run in mine and she runs great. Royal Purple is pretty good stuff my brother use to run that in his and he had no complaints. I think it goes on the person.
all the synthetics are very good.have tried/tested many,mobile 1,castrol,royal purple,amsoil.all do a very good job.have used them in everything from my john deere l/m to 1000 hp 565 in my bracket car.
yeah i buy the cheaper filters they flow better...like microguard and ones like that....I just wanna try all the different synthetics before i just stay with royal purple for all I know my car may like mobil 1, amisol, castrol, etc...so i'm just wondering who has had some good experience with what!!! thanks!

I run amsoil in both the mustang and the driveline of my jeep. but i do run the cheap stuff in the jeeps motor since it has high miles and needs a refresh.
