I was wondering what I had paid for Red Line 5w/30 last year.

I dug out my receipt for the three gallons of Red Line 5w/30 that I purchased from the folks that @HEMIMANN (EliteRaceFab) had issues with his order and their price back in March last year for the three gallons was $126.24. I thought that that was reasonable back then ... the days of good service and fair prices are gone out the window.

To sum it all up, Amsoil is the better fully synthetic oil with Pennzoil Ultra coming in a close second. However, the price difference between the two is quite significant. So Pennz is the better choice.

It is impossible to sum up 4,676 pages of this thread like that! Unless you started reading it when you joined

Unless your Hemi sounds like a rock crusher on it, like my 6.4 did. Thanks for the oversimplification.
