Royal Purple vs. Mobil 1
All the oils on the market today are Blends except Amsoil.
Technology moves forward and petroleum oil does not .
Royal Purple Failed the test right out of the bottle
I would highly recommend you avoid buying oil at Walmart because we all know Walmart does not make oil or any other petroleum company because it is a derivative from crude. These oils have Parriffin and Sulfer which the two make a wax and this is where the Varnish and Sludge begin to form in every engine. When you take your oil cap off and see the brown color that is the varnish.
We have Amsoil users here and they recognize it for what it is. A good oil for extended oil changes. They don't come here and badger other brands or attempt to sell their products here. If you came here for sales, you need to pay for advertising.
i can speak personally on rp-i race mx bikes ,i was sponsored by them,just because i get a product for free doesn't mean i will endorse it-i know i'm talking motorcycle transmissions,but their 10w40 mc oil in the trannies of my 2 strokes broke down almost instantly,when i did use it in my vehicles with a k&n filter, the oil analysis came back less than stellar,after switching to amsoil,not only did my trannies shift better in my mx race bikes as well as my road race bikes,the analysis were head and shoulders above the ones from rp, even after once a yr oil /filter changes,as a matter of fact,i racked up over a million miles on my personal biz van and last 3 p/u's and wife's last 2 cars,zero engine issues-
I am an Amsoil supporter and personally use the 0w-30 signature series changed once a year but I have only presented facts here not propaganda. Labnerd and others are very educated about oil and will tear you apart. Making your user name Amsoil is just asking for it.
The only thing I disagree with Labnerd on is his opinion that Amsoil's testing is crap. They use industry standard tests and they are the same tests all the oil manufacturers use. I know he doesn't like the 4 ball wear test because ALL the oil companies have used it "incorrectly" but at least they are all on equal footing when Amsoil beats them.
For a great site (yes he is an Amsoil jobber but also an engineer that was a member here and drives Ford trucks) check this one out:

One oil vs another oil comes down to "you" buying into a companies marketing ploys. I personally go with a case lot sale of 5w20 or 30 and run with it. I'm using PP right now only for the sake that it was on sale at Walmart....my truck runs good on dino or syn. When it comes to gear oil though, I only use Redline.
yea, run it to full temp, It will burn off any condensation that might have accumulated internally due to temp changes. Also by driving it will help relubricate the drive axles and transfer case. Using a full synthetic is better for it because it will flow quicker through the engine, especially in colder temps. As for becoming acidic, not sure about synthetic oils. I know conventional oil will do it. My opinion, I don't think they do because they are made of syntetic properties, not natural.
