I managed to score some Mobil 1 5W-20 at Advance Autoparts at a pretty good deal so I decided to go ahead and buy it for the 2011 5.0.

3 gallons is normally $83.97 ($7.00 Qt)
3 gallons at $65.97 on Sale - Buy $60 get $25 Off Promo Code is $40.97 ($3.41 Qt)
3 gallons at $65.97 on Sale - Buy $50 get $20 Off Promo Code is $45.97 ($3.83 Qt).

So 6 gallons takes care of the first 3 oil changes after break-in is over.

Funny thing is the Date Code: They are all D26A which is April 26, 2010.
Guess what my cars build date is.... 4/26/2010.
Happy Birthday! Guess you might say they were made for each other!

 

There is no break in period on cars anymore...it's not 1955

 

Might be old fashioned, but I'll stick with a "break-in" period. You go ahead with the "break-it" period.
IMHO, LOL!

 

Basically engines today never fail if you follow the owners manual...I'll bet you could change the oil every 10,000 miles ( as recommended) and not have an engine issue for 200,000 miles. You'll have issues with all the accessory stuff like a power window or A/C or electronics. Spending that extra money just makes the owner feel good.
