Hey all - I run 0W30 in my 5.0 XLT and since I love the performance of it so much, am thinking about putting this in my 4.6L Northstar SLS.
What do you think?
It calls for 10W30, but my X called for 5W20 and running 0W30 is no problem on it.
Oh yea, I know the numbers mean fluidity, but why does a 5W protect "better" than a 10W in the cold? And, why does a 10W protect "better" than a 5W in the hot?
Thanks!
