I went Amsoil because frankly I have no confidence in Redline handling 7,500 miles. Maybe it can but I am not sure. Redline is more performance focused.
I wonder why Redline makes your K24 run quieter.
Picked up 10 qts of OE and 10 qts of Signature Series 0w-30 from my local dealer. The membership brought the bill way down. Amsoil is cheaper than the rest. Surprisingly the dealer was open today for a few hours.
Mine got to 230 driving around town. I have made up my mind, I'm going 30 weight. Doesn't matter how good Amsoil and Redline are, 0w-20 is 0w-20. 40 weight not now, I'll take my time and see how things go
Yeah I saw your post. You said that you were having that dry start problem. That's pretty normal on these motors. If it bothers you, prime the filter each time before you start the Jeep. You will notice a drastic difference.
It is said that this 3.6 is the new Pentastar Upgrade(PUG) with a redesigned valvetrain so I am not sure any viscosity other than the 0w-20 is a good idea. Having said that, both Redline and Amsoil 0w-40 are very tempting.
