5w-20 vs. 5w-30 motor oil?
I'd like to hear people's thoughts on this topic because I have heard many different opinions Is 5w-20 really a necessity in the the new Ford engines?
I drive a 2005 F-150 4.2 liter V6 and I use Mobil 1 5w-30 during the hot months (I'm in Florida so that's about 8 months out of the year) and I run mobil 1 5w-20 during the cooler winter months. I change it at 5000 intervals. I only use a mobil 1 synthetic filter, and I change it every time I drain the oil.
Any thoughts, praises, questions, criticisms? I'd just like to hear people's outlook on this. Thanks.
