Switching to synthetic???
I have a 2002 GT and it has 3.73 gears, bbk TB and Plenum, S&b cold air intake, and a pro 5.0 shifter, o/r h pipe and flowmaster 40s. I am currently running the ford motorcraft syn blend because that is what the car has always had in it (Previous owner always had it maintained at a dealership) I am wanting to switch oils but am not sure what to switch to. I was told royal purple but others said to stay away from full syn. Thanks!

Mobil1 is what I run. Royal P is great oil but with that stuff you'll need to change your oil more often due to the amount of detergents and Additives wear out really quick and RP costs almost twice as much so not only will you pay more but you'll be changing it more often.

They say you can
How often should I change Royal Purple in my passenger car?
Royal Purple recommends following the manufacturer’s maintenance intervals while the vehicle is under factory warranty. In clean engines that are no longer under warranty, oil change intervals may be extended up to every 12,000 miles or annually, whichever comes first. Oil filter changes should be done as recommended by the filter’s manufacturer and oil should be topped off as needed.
In dirty engines, Royal Purple recommends the standard 3,000 to 5,000 mile oil and filter change interval until the engine oiling system is clean and free of deposits left by lower quality oils and / or poor maintenance or mechanical problems. This will allow time to gradually remove existing deposits without overloading the oiling system. Mechanical problems such as fuel dilution, coolant leaks into the crankcase, poor air filtration and / or failure to maintain proper oil level are all detrimental factors to the service life of any engine oil. Any one of these factors can significantly shorten the useful service life of any oil.
