Wow my oil pressure is very high compared to you guys. I run at hot idle in park about 45-46psi and 54-56psi cruising on the highway.
This is the back of an Amsoil 0W-40 SS bottle for my 6.4I think with Amsoil, their claims are "meets or exceeds" but they have never been certified officially. I'm sure most good oils meet the requirements but aren't actually certified which I why you won't see the donut on the bottle.
This post was very informative, and good info on the graph, then the last sentence. Seriously. Just stop. Some of us are trying to learn and get real info and then you add that in.......Can't compare running QSUD and Redline. Even QSUD's top oil blatenly run Viscosity Improvers proudly. That is how dumb the general public is, QSUD tells you they use their brand of corn starch to hold viscosity and nobody does the research on what they give for that benefit. Of course those who pay attention would know you give up shear. The HTHS on Redline 5w30 is 3.7, if QSUD's is higher I stand corrected. If the oil is reputable, you should be able to find HTHS. At the end of a interval, you pay a price having having an oil with impovers. Like Raven said, 4k miles would be a better idea.
There is a reason why QS tests lowest on high temp high shear on all of these test oils. There is also a reason why Amsoil didn't want to include Redline, if Redline was on this graph they would be off the chart as it was 30 weight that was tested. The chart shows the range of 2.95 through 3.23 as the highest oil tested, and toss Redline 3.5 for 10w30 blows the chart out of the water. Also why I recommend 5w30 over 10w30 or 0w30, the 5 weight is usually a better oil across the board. But hey I'm sure the hacks will attempt to divert common sense.

Not "Certified". Just like Mobil 1, Castrol, Valvoline, Red Line, Amsoil, etc., they are all "Recommended For". The only oils I know of that are both API SN and Chrysler MS6395 certified motor oils are made by the Shell oil company.

This is the back of an Amsoil 5W-30 OE bottle.
Amsoil's OE and XL line of oils are API certified. Great for people who are worried about warranty issues.

Also doesn't 5W-20 sheer less than 0W-30 and 5W-30?
What flavor are you running?
