5w-30 oil
According the owners man. my wife's 2003 explorer is supposed to take 5w-30, but due to the fact I'm lazy and I can buy Havoline 10-30 at Sam's for a pretty good price (mine dosen't carry 5-30) I've been using that. Down here in Texas it just dosen't get that cold that often, so I can't imagine I'm really doing anything wrong here, but some feedback from wiser individuals than myself would help justify my laziness. Thanks

it will be fine just it won't meet the 929a spec which is required for warranty. also it will have less moly and Ca. than the 5w30 havoline. chevron supreme is the same oil. and kragen sells it for 1.50 and .49 on sale.

Anyway, in Texas never go thinner than 10w30.

From the spec sheets, the difference in viscosity at 40C varies as much between different brands as it does between 5W-30 and 10W-30 within the same brand. Mobil 1 10W-30 for example is thinner than Mobil Clean 5000 5W-30. You are not going to notice the difference between a -20C and -25C cold cranking viscosity in Texas, and that is the only difference in the spec.

Now TP what on earth do you mean by that? Just this last Wednesday I decided to drive the SCrew and it was showing 121F on the dash at speed. I run nothing but 5w-20 and have single digit wear metals at 5,000 OCIs. The thinner oils meeting Fords specs will have better/greater film strengths, have fewer allowable deposits, and transfer heat quicker resulting in a cooler engine. jimandmandy would be correct concerning cold flow properties for Texas. It just doesn't get cold enough here to worry about it. Minnesota, yepper, Texas- ain't happenin'.

Geez 'O Man!
You guys sound like residents of the old folks home sitting around and talking about their latest bowel movement.
QS, PZ, Castrol, Mobil, Exxon, Texaco, 5w-30, 10w-30. His engine is not going to know the difference.
Suggesting that it takes a NASA supercomputer to help decide whether to use Brand X 5w-30 or Havoline 10w-30 is a little overkill, don't you think? He asked a very simple question. Give him a simple answer.
Finish the paperwork, pull the chain and move on.

But everything is a compromise and while a thinner oil may run cooler (but not if it is too thin), it also does not pass as large of contaminant particles through the bearings and so potentially could result in higher wear metals if such contaminants are present.
If the "thinner oils meeting Fords specs will have better/greater film strengths" than say a 10w30, why is it they have lower HT/HS viscosity? Isn't that closely related to film strength?

Okay, so make me use my brain. Here are the numbers of the Havoline 5w-30 vs Havoline 10w-30 concerning cold pour points:
5w-30= -33F
10w-30= -31F
Not much difference and certainly within any cold temps you are going experience in Texas.
