So burla i did change to redline 0w40 in my 6.4. I can't say the motor is any quieter i always had some piston slap when cold and that hasn't changed. The motor is always very smooth when warm. But i did notice i now idle at 32psi oil pressure when it used to be 28psi and when warm its now 52/53 when it was 50/51when running down the highway before. This is coming from m1 0w40. So far happy with the redline. I also am using a rp filter when before was m1. You think the oil psi is in the filter change or oil.

The slightly higher oil pressure could also be from the oil temperature being cooler. The ambient temps have been getting cooler, the oil cooler is absorbing more heat.

Redline 0w40 like all other Redline oils are on the higher end of the given viscosity. Completely normal for it to show a slightly higher oil pressure[emoji106]

Try redline blue label 5w40 to see if your “piston slap” goes away.

I use it in michigan.

Redline 5W40 pour point is -49F

You are perfectly fine.

People in the upper Peninsula of Michigan and Canada and even Alaska run 15W40 oil in their trucks. 5W weight will be fine in any of the 48 states.

I run PUP 5W-30 in mine wouldn’t hesitate to run QSUD 5W-30 either. Of course I use RP filter.

Mine is an 08 and has like 173,000 on it. I changed all fluids when I got it. Have Maxlife full Syn in transmission, transfer case and power steering and then redline in the axles. I am not a GM guy but do love the AWD it is amazing.

I think im going to go with QSUD. You running the 10-48 filter? I run the big one in my ram and have heard of too many issues with the smaller one (not that it is a ton). So im kinda leaning towards the wix xp filter. Fluids is next on my list. i have a couple slow leaks (more like sweats), so keeping my eye on them. i have never been a gm guy either. drive plenty at work. But i do love this 6.2. i love how smooth the power is. I do however wish it was the 4wd version. The awd will be perfect for the wife, but i would rather have the extra power not being awd would provide. I just may try to hunt down a 6.2 tahoe in the future (2009). We do love our yukon. I look forward to driving it in a snow storm this winter. I threw new 18" wheels with falken wildpeak at3w tires on it. Gives it a whole new look.

Cool thanks im going to try it. I cant get myself to dump that new redline just yet.

So most of us who have our ticks killed with redline had it happen after 500 miles and up to 2300 miles after an oil change, that also matches the science of the formula. Don't dump it. But, also if you were using it to kill ticks the 5w40 redline is absolutely the way to go. As Kyle said and as we all know, the formula 5w30 for the 5.7 and 5w40 for the 6.4 are the special hemi tick formulas. They have been proven better then even 10 winter rated or 0 winter rated redline formulas. So hold off and run your normal oci, see what it does in the future, but even if 0w40 killed the tick I would still use 5w40 redline if it were me.

You have a pao base oil, so it is literally the best performance you can get in the cold. See the second line in the graph. This is why when you see redline next to most group 3 ils below 20f you see them starting to get cloudy but the redline is crystal clear. If you look at the chart, the green is the NATURAL operating temp of pao, to get into the margins you need additives that are temporary called vii's. 0w40 redline uses such additives more then their 5w40, meaning the 5w40 will be more stable throughout the oci.

Even 5w40 that isn't pao has decent cold performance. But redline's formula is even better then this chart which is for mineral oils.

The only 5w30 that comes close to redline for cold flow is m1, but as you can see it is slower and starting to cloud. Redline 5w30 is as good as the 0w30's, you can expect 5w40 to be similar. When he flips this the first 5 from left to right are 5w30's, I bet you can see the redline 5w30, and the last three are 0w30's.

If there is an oil better at stable cold performance then redline, I am not aware of it. The argument is CCS, but there is a ton of reasons why CCS doesn't tell the entire story, again PAO's natural state is pourability in colder temps then any other base oil used in engine oils. When you see used oil cold pour tests, you see the 0w30's slow down, because the vii's are shredded, there are some of those on the net as well. But since PAO's flow colder, even when used you will see them pour better. CCS doesn't address this fact, or the fact that some oils are thicker at startup by design, but still flow adequate.

I want to see motul vs redline across the board in all the test we know.

Motul 300V has excellent moly and is is ester/pao based. I think it’s one of the few major competitors with Redline. We just hardly see anything about it.

Is it pao based? I thought most Motul was ester/group 3. Corey's find didn't show 300v, but you can see this one would be group 3. Does nick sell 300v? I bet if he doesn't he can probably get it. Kyle you trying 300v in the 6.4 at some point?

Nick can get it. I tried getting some Motul 2 stroke oil from him and he had to be set up as a vendor. Motul is being a pain in the butt and will only provide him 300 V at the moment.

I could be wrong. I thought PAO and ester. Could be Group 3 and Ester.
