So I was searching to see if they're was a newer oil spec than Ford WSS-M2C945-A for 2014 mustangs (btw, there isn't) and came across mustangevolution.com. All these guys with 2010-2013 V6 Mustangs were warning their new guys to NEVER put "regular" oil in their cars because it would increase wear and could damage the engine...almost made an account so I could tell them that any "regular" oil that is API GF5 would meet the spec for their precious little pony...they may have just s**t a brick. But it was a year old thread so I let it go, I've learned so much here that stuff like that drives me crazy...and if DNewton is reading this, they're also dumping their MC syn at 5k miles, morons.
