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?

I work at the ExxonMobil refinery in Baytown Texas and recently took a sample of my used Mobil 1 5w30 with around 6k miles on it into our lab for testing. They reported back that the oil was still good for continued use. Of course I changed my oil anyway but I will continue to use the Mobil 1 brand. Today a saw a new blend in Walmart, 0w30 its supposed to improve gas mileage by 2%, gonna try it for my next oil change.
