Been running PUP 0w40 since FF. Blackstone oil reports are good. Get a hot idle tick after 4500 miles, Quiets after oil change. OCI approx 4k to 6K. Total miles, 42K so far. Next change to Red line 0w40. Going from there.

I was going to change to red line also I noticed they have A 5w40 was thinking about going with that instead of 0w40. Idk Do you think there would be any benefit to the 5W instead of 0W

Oil Viscosity Revisited. **** sorry i did not see this other post

There's a chitload of info over in the SYN thread, although doing a search is time consuming,over 3400 pages. I personally think using the spec weight oil while under warranty, mine 42K PUP currently ( to redline 0w40), would be "safer" . With the oil analysis all good, on my 6.4, may later switch to 5w40.

5W-40 Redline has been ran in a couple guys trucks and they have great results, probably the best of all the 40 oils. @U&A is the guy to ask


2018 2500 6.4 4x4 4.10 Amsoil SS 0w-40, Softopper
Black Rhino Arsenal 18x9 +12mm
Cooper St MAXX LT295/70R18

2016 Durango 5.7 AWD 3.07 Redline 5W-30 RP 10-48
1996 Nissan Altima 2.4 Amsoil SS 5W-30

Changing from PUP 0w40 at 42k miles, to Redline 0w40 and RP filter. Been doing great with wear with Blackstone reports, but the PUP develops a hot idle tick at 4500 miles like clockwork. Goes silent after an oil change,will post back later.
Edit update 10/03/ 19: RL 0w40 in with RP 10-48 filter, sound's real quiet, just the normal injector noise, and chirping exhaust at start up. same as PUP, will see if the engine stay's quiet longer.

So what is the theory behind using redline 5w over 0w as recommended per OE? As in, what’s the benefit?

Also, I’ve previously read that the rp filter to go with was the 20-820, but amazon says that doesn’t fit. Sometimes amazon is wrong, but it does say the 10-48 will fit. Will either of these fit?

Little thicker on start up. Maybe sticks to metals better then 0w. Im due for a change not sure if im going 0w40 5w40 or 5w30 yet. Redline for sure. They say on there website that 5w40 is equal to a 20w50 conventional. Not sure if thats to thick on start up in the cold. What you guys say

Wouldn’t there be concerns of loss of power or decrease in mpg with a thicker oil?

 

[DarthMegaHD]

And with colder months coming up, don’t we want thinner oil for easier starts?

Hope you all changing to something other than recommended don't have the MaxCare warranty. If so, knowing how quick FCA is to deny coverage for the littlest things can you conceive how quick they'd deny a major engine issue if they discover you've been running a non-sanctioned oil.

0w tastes better

very little difference between 0 and 5 if you live in a warm climate

I guess this is my problem. I never owned a motor and i have had quite a lot that gave a **** what oil i ran. Now i never went way out of spec either. I ran m1 in my 1500 5.7 for 115k with not one problem. Im gonna stick with ow40 in my 6.4. I run m1 now just may try 0w40 redline .
