Hi! i just bought a 06 Mustang gt 5 speed, All stock It has a quicki lube sticker on the windshield that says penzoil! I heard that penzoil is bad because of some plastic coating it puts on the engine?! is that true? what is everyone else running for motor oil? Full synthetic? synthetic blend?" what name brand? Thanks guys!

 

Personalty i use Royal Purple, and only Royal Purple.. Some say i baby my car too much, but i want it too last so you gotta do what you gotta do lol.

 

I use Mobil 1 full synthetic 5w20 oil. But I might switch to Royal Purple.

 

Motorcraft 5w20 semi synthetic available at WalMart for cheap along with the Motorcraft filter every 5k miles.

 

lol no thats not true. pennzoil makes good oil so dont worry.

 

Oils I like. Amsoil, Pennzoil Platinum, Mobil 1 Extended Performance. I beleive in full synthetic oils for newer cars. I stay with Ford recommended 5W20 (0W20 Amsoil). Use a good filter and change it with every oil change, such as Motorcraft, Purolator Pure One, Wix, Amsoil, K&N, Mobil 1. Motorcraft is probably the best bang for the buck and a damn good filter. Avoid Fram. Just my $.02 worth.

 

I think that you cant go wrong with the previous suggestions. I would definitely recommend a full synthetic either amsoil, or RP with a high quality filter. I prefer the RP oil filter with 6 quarts of the 5w-20 RP in my GT.

 

i use the motorcraft FULL SYNTHETIC 5w 20 with a k&n oil filter... the qts are 3.50 and it is damn good oil i have read alot of great thing about the motorcraft full synthetic oils

 

pennzoil platinum 5w30.

 

i guarantee you that penzoil leaving a bad plastic coating on the engine topic is just a rumor. Penzoil is good, but you should go synthetic (Royal purple/Mobil 1).
