Royal Purple f/synth
 

ok, hope this is the right place to ask. I have this strongest urge to start putting / using the full synth royal purple oil for my 08 s/c stang, i hear from reliable people that it is good chit an well worth it. Its my only car and i love her, i think she deserves the VERY best, you guyz and galz agree ? Royal Purple ?

I've seen comparisons, and RP seems to outdo mobil1. Although Ive never had any experience with Amsoil, it seems to be the best oil out there, and can be ran for many miles at a time.
