oil, what's the best? Options

[garin]

i wanna switch to synthetic oil for my 94 gt. i have castrol gtx 10w-30 and a fram filter in it now. i though about royal purple and castrol sytec. i heard that castrol syntec isn't the best synthetic oil and i also heard that royal purple isn't good if your car has over 90,000 or so miles. so i just wanted to hear what people have to say. my friend, who has a 2000 gts said that mobile 1 and an oem filter is what people recommend for his car. so what is the best synthetic oil and filter for a 6gc?

been using valvoline full synthetic 5w30

good stuff - i use there Synpower in 0w - 40 in all me motors. i used to use mobil 1 but our local trade counter doesnt stock it and large motor factors charge to much. looking at £40+ for the Mobil whereas i get Valvoline for £25. i changed to valvoline about 5 years ago and havent looked back. as for filters - like others have said dont use fram. over here i use blueprint filters - exact same as genuine toyota ones but half the price. never had a problem with any blueprint part.

for higher mileage engines i've heard the "maxlife" oil Valvoline comes recommended but i have no personel experience of it - i have no probs in a 3s-fe i have which runs on Synpower and that has 110k miles on the clock.
