Who uses this goop in their stang? Wondering if it'd be worth putting in? Currently I have Motorcraft synthetic 5w20. Should I switch or is my Motocraft fine? Would the purple stuff be better for the blower? Was looking on ebay and Purple is kinda cheap.

well i just spent a bunch, and switched to royal purple.
engine runs a bit cooler, and on start up its not as loud, waiting for the oil.

I run Royal Purple 10W-30 and have had good luck with it in all kinds of weather. My oil pressure seems to be very good all the time as well not to mention it pumps up to pressure almost instantly. Bottom line is go with a quality synthetic you trust. Any full synthetic is much better overall than any conventional oil. Try these links:

I saw some article that they made with the myor syntech brads and royal purple came on top oveall. I think they freed up some HP don't know about that but I relly like it.

Hey, i don't mean to sound like an idiot, but i was recently thinking of switching to synthetic oil on my next oil change. My car has a little over 100,000 miles on it, and i'm not sure what kind of oil was used in it before i got it. Will it hurt my car if i switch to synthetic oil with the amount of miles i have on my car. I know it seems like a dumb question, but i'm not familiar with synthetic oil, so any advice will be appreciated.

as long as you go with the same oil weight you'll be fine.

^^^ This is correct and the synthetic will be much better for your car.

well.. now i'm torn. should i stick with my motocraft synthetic or should i upgrade to royal purple? does anybody know for sure if it does what it says it does? i'm not worried about the freed up HP and shat. i'm just worried about it protecting my engine components and shat.

I run it in the car front to back and haven't noticed anything odd, other then the 1-2 of the 3650 being smoother.
