Don't mean to hijack the thread but Unleashed help me out... 2014 GT Mt currently 5k miles, I am running nitrous and E85. located in Chicago, IL. Car sits in the garage 6 months out of the year but when I drive it its driven hard. Do you still recommend Amsoil AZO 0W-30 or should I use Amsoil RD30 10W-30?? with spray I am right past 600rwhp
@UnleashedBeast,
I have been running the recommended Motorcraft 5W-20 in my car that is detailed in my signature for the past 35K miles and I just happened upon this thread.
To confirm, since I drive my car year round, including snow and ice, and do have a 50/50 mix of city and highway driving, and have less than 400 WHP for now, I should use the Amsoil AZO 0W-30?
With all due respect, my Boss 302 says 5w50 on the cap and in the manual. If there was an engine failure and you had, say, 10w30 or any thing other than 5w50, aren't you asking for trouble warranty wise? Could they not void the warranty? Why would Ford recommend 5w50?
Personally, my 2013 Boss 302 is running what the manf. calls for (Motorcraft 5w50) until the warranty is up.
BTW, I'm not trying to a smart a$$ or a troll, just educate me on why you would not use what Ford recommends?
If Ford is going to void your warranty for running a less viscous lubricant, they would void your warranty to using Motorcraft 5W-50 after 1,500 miles. After that few miles, Motorcraft 5W-50 is always a very light SAE grade 40. Some samples were a heavy SAE 30 grade. Ford states you can run this lubricant up to 10,000 miles if I recall correctly (for normal street use).
