So I changed my oil in the Mustang for the first time today. I went with motorcraft synethic blend and a motor craft oil filter. It says to use 5w20 but all they had was 5w30 that is going to be ok right? Also it the book at the store said 6 qts. is that right.

Your be fine man.i did the same thing one time before and it did not hurt it.
and yes it is 6 qts.

mvr

yes the 6qts

and alot of people say on higher milage engines to use the 5w30

yeah 5w20 is the recommended one, but you can always go thicker oil which in this case you did, 5w30. i actually just did an oil change today w/ Castrol GTX Synthetic Blend 5w30 because they ran out of 5w20 at Autozone :] but i used 7qts...[&:]

i run 5 30 and it seems to be doing just fine. I think ford recomended 5 30 in the 4.6s for a while, maybe until like 2000 or so.

nah my original oil cap said 5w20 and my new one also says 5w20 both caps were bought from ford dealership

My manual as well as local Ford dealer agree that it is 5w30.

I use 10W-30 synthetic here in Florida. It never goes much below 35° here, coldest it's been in 15 years is 28° and that was only for an hour or so just before dawn...[/align][/align]In the other higher-mileage vehicles I run 20W-50 MaxLife dino oil (I ran a supercharged '90 Miata to 350k miles on this stuff), the Mustang will berunningit too when it hits 120k orwhenit starts consuming any oil between changes (every 2500 miles--my grandfather always said "oil is cheaper than engines").[/align]

is 20w50 safe to run in our engines??

They switched most V8s in Fords in 2001 to 5w20 for "fuel economy." HA, lol. 5w30 is fine, its just a thicker at operation temperature, your still good, I run 5w30, you should consider full synthetic for next time, nothing but the best! RP or Mobil 1, etc...
