Looks like a strong report. I have 30+ quarts of this exact oil in my stash, will be using with confidence. Thanks for sharing.
Nice report. Have you always used a 20 grade in that engine? Up until 2006 it called for 5W30, they made the change to 5W20 in 07.

Last 2 changes was on 0w20, but other than that its been on 5W30.

Sump is 5qts and no it didn't use up any oil.

Looks good. I would run 0W30 or 5W30 if that is what is spec'ed.
Very good report.

The jeep is back on 5W30 qsgb. I ran the car on 0w20 to see if it would of caused excessive wear on a nonspec'ed car.

Well you got you're answer.
A good report.
RP 0W-20 held it's viscosity with no oil shear.
The reason engines that were once spec'd for a fuel conserving 5W-30 dino have no problem running a 0W/5W-20 today is because the base line or minimum standard for motor oil has improved a lot in the past 30 years.
In other words, you may have been running a grade lighter than what was originally specified but in actuality the oil was likely heavier at the end of an OCI than some cheap 5W-30s were in the past.
