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.
Well, oil is pretty cheap when it comes to cost of ownership.
XW40 trumps XW30.
Ok? I wasn't arguing viscosity? Did you quote the wrong person? Or just a couple Molsons deep?
Technically there is no reason any viscosity that flows won’t work. Sure a 40 has a bit higher viscosity at 100°C but the valve train would be just the same with a relatively thinner viscosity oil at say 60°C or whatever temp the viscosity is the same as the SAE 40 oil. Think about it.
Redline is the bomb. Love it. You'll be perfectly fine with each but Redline is more robust and Amsoil is focused on extended drain intervals which I'm not a fan of.
If I go 40, I'll definitely go Amsoil. Redline is way too thick. Thanks for the OE idea, I need something less expensive to break in the motor.
I don't hesitate to go up one grade thicker, i.e. -20 up to -30, but not sure I'd go to -40 unless they spec that for this engine in other regions.
RL does not hold back. Their 5w40 even more stout.
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.
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
You could add HPL (High Performance Lubricants) to your list if you are willing to spend that kind money. All three are really high-end oils compared to the Majors. I personally would move up to a 0w-30 or 5w-30 though, maybe even a Euro oil to get your HTHS >3.5 or higher. That is just my advice, not saying it is correct. Most people on this site are more knowledgeable about oil than I am. There is an Amsoil dealer right here on Bitog, he is called Pablo. Put his name in the search, he will pop up.
Do you have KRL results on both oils? Probably can’t say which one is more shear stable without that data, since every single engine will have slightly different fuel dilution, points that may cause VIIs to shear mechanically, etc.
Use the (at) symbol in front, so the people you’re referencing get notified in instances like this… @Pablo or @HPL Plant Manager
Thanks Subie, you just taught me something!
Their 5w30 is liquid gold. I still don't trust 0w anything as a catchall. No real point in going 0w for me in Texas.
