Your manual should call for 5w30 like my 01 4.7 does. You can run the 10w30 if you want as long as you do not get the colder winters like we have here in Ohio.
I have run Mobil 1 5w30 since I bought it without incident. I think the correct weight is more important than the brand as long as you change it at the proper interval.

Weight is not just thickness guy's. The weight refers to additives. The manufactures build the internal components of the motor with oil companies helping them along the way. This partnership creates lubricants that don't break down to the internal mineral makeup of the working parts of these motors. Basically, if you install different weight of oil into a motor that was not built for it could have adverse effects. The composition of the steel used in the internal parts of the motor can taint the lubricant properties and deposit sludge of ware the motor out.
One should use the lubricant that the factory recommends. Look into your owners manual at the abundant temp chart and figure out which one you should use according to specifications.
If one is to use a different oil weight they should make sure that all specifications are included for the operation of the motor of which it needs.
According to normal use instructions in normal outlying areas you are to use 5W-30, and in climates that are always above 0 F then 10W-30 is recommended. May I recommend Mobil 1. I know for a fact that their Full Synthetic is true. The government put standards on the oil companies and in these to claim a full synthetic it either must go through a timed manufacturing process or be broken down into 2 molecules. I know that Mobil One is fully broken down like it is suppose to be. Many cheap companies will just mill it to the time and call it. This is why there are cheaper products out there. Do not use blends because they are not any better their just cheaper. If you do Fully Synthetic which is the best choice then use that. But is regular is used just use that. Mixing does nothing better because the oil properties still have the same defaults that are in the regular oils so they break down just as fast and ware just as fast as regular oil.
Full Synthetic should be changed between 5000 and 7500 mile intervals according to your driving habits. Regular oil is 2000 to 3000 according to your driving habits. Blend's are the same as regular like I said. So yes Full Synthetic is more expensive but you actually save money because you do it so much less and less ware will happen to your motor. When first changing over to Full Synthetic you should change it in the time zone as the blend because of residual oil in the block and cooling systems if equipped.
Last but not least remember this:
Materials Added to Engine Oils
The manufacture strongly recommends against the addition
of any additives (other than leak detection dyes) to
the engine oil. Engine oil is an engineered product and
it’s performance may be impaired by supplemental additives.
This means NO additives!
