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?

was using castrol syntec 10w-40 with k&n filter.
then suddenly changed to mobil 1 10w-30 with mobile 1 filter. both are good but i get slightly better gas with the mobile 1 **used both 30 and 40 for both** -------------------- I don't normally drive fast, but when I do its on a curvy section of this island
