6.4L Hemi Oil Choices

[tpk0999]

Boy, I didnt read that you have to change at 2k miles. Of course... they dontngive you the owners manual anymore. Cheap asses. I was really debating on picking up some of that liqui moly. I have about 800 miles on the truck so I have some time to research.

I use redline 0w40 in my 6.4. Engine sounds great but i do have some cold weather start up clatter. Only for a few sec's but it is there.

Amsoil SS 0-40. Best additive package and the only true synthetic oil on the market. And if your hemi has a “ tick” get tick shampoo, you have a PROBLEM! Take it in and make them fix it!

We have guys running 5w30 redline in the 6.4, and so far u&a loves it. Mind you 0w40 redline is way thicker then 0w40 fca specs.

0w40 redline operating visc 15.3
0w40 srt hemi oil 13.7 but shears a lot, at the end of interval cSt in 10's or 11's. look at uoa's blackstone thread.
5w30 redline operating visc 11.9 but most uoa's have it over 12. redline 5w30 is way thicker then 0w40 srt oil at end of interval, no shear.

My point is this, 30 weight even 5w30 will flow better in the cold then 0w40, but 5w30 redline will even be thicker at operating temp then srt oil throughout much of an interval thanks to the shear from 0w40 PUP/srt. Basically, 5w30 redline performs better in the cold and warm then 0w40 spec oil.

Broken down even farther.. 0w40 is supposed to tell you something about the winter rating and the weight, but in reality they both are wrong with this particular weight with fca spec. The winter rating is misleading because of the weight, it is no where near 0w30 or 0w20 in cold performance, 40 weight is too thick. And to make it worse, the 40 weight is not a true 40 weight, because of the swing winter rating to weight, the oil is full of temporary additives to make it seam like 40 weight, when in reality 0w40 srt oil is a 5w30 most of the time in the sump, FACT.

The advantage of using 5w30 outright is less swing winter rating to weight, meaning less vii's, meaning less contaminants during the interval. But not every 5w30 is appropriate, it should be a "thick" 5w30, in the high 11's cst. I say this because you are already using redline, most of the time I don't get people to switch brands, but maybe you should switch weights, imo 5w30 redline is the best choice for the 5.7 or the 6.4, and the only time I would go off of that is if you still had cold piston slap you could even use 0w30 redline in 6.4, for same reasons the cSt will be thicker them 0w40 throughout the interval, but the 0w30 redline would be as good as possible cold performance.

Flat out 5w30 redline is hemi honey, 0w30 is a close second. It has everything a hemi needs, good hths, great additive package and base oils, and most importantly very good cold performance. 0w30 redline you loose a tad warm performance but will even be better cold performance. I think the only 40 weight redline that should be used in the 6.4 should be 5w40, and this is because of the guys who tested this prior, guys like kyle and tj. But you wont like that if you have cold tick, which it sounds like you do, that is why i say look hard at 5w30 or even 0w30 if you have poor cold performance.

Look close at these charts.. mind you 0c is 32f, so look how thick all oils are even just at 32f!

5w30 will be over 250 visc at 32f, and 40 weight will be better then 3 times that. That is why you get cold tick, the oil is so thick there is no oil on the lifters. Also, you can try putting hammer down to the floor before you turn key, pre oil lifters, then take foot off gas, (your truck wont start just turn over and rotate without starting), then start truck how you normally do, in theory this should oil lifters at start up. worth a try anyhow..

Im gonna go 5/30 next change. Thanks for the input. I will post up the results. I need it pretty soon here.

Sale on Amazon for $9.45 per quart, case of 12. I just picked one up.


I'd add to Burla's always thorough advice that 5W-30 Red Line has extremely low high temp volatility, meaning it doesn't boil off much. The corresponding NOACK value is 6.0.

And - recently discovered is a Hemi "pre-lube" function so you don't have to change to a winter 0W to prevent piston slap and hydraulic lifter fillup. You simply press both down both the brake pedal and the throttle pedal (to the floor), then crank. Then engine won't fire - it will keep cranking. We can do this in 15 second cycles (so as not to fry the starter motor) until we see oil pressure in the gauge - then release throttle pedal and start. Magic! No more cold start clatter. Software is grand. Sometimes.

I feel like I need a shower every time I order from amazon. I order as little as possible from this place, it is surely ruining America. Some day in the not so distant future we will regret having giving amazon/google, youtube,facebook all the power. With Nicks prices being so competitive, most of the time we should be using him. Nick really gives this stuff away, cheaper then anyone on the net with the exception of this one time one weight on amazon.

 

[Burla]

Price check nick again summit, jegs, ebay, and others, yes Nick is at the low end of all of these shops, and in fact cheaper then 95% of them. Every day price, we are grateful he serves us redline.

Thanks, we try our best to give the best price on everything especially the ever so important Hemi Honey!

Put the correct oil in your 6.4. It calls for 0w-40 USE IT!

Sorry to resurrect an old thread, but I hope to be getting a 2500 soon and was researching oil. Mobil 1 0W-40 is so easily found on sale at Costco that I would really love to use it. I see that Redline 5w-30 seems like the hot setup, but if people are having decent results with the Mobil 1, I'd be hard pressed to justify the cost difference. So...is it worth it?

I thought about using redline. but stayed with pup since i dont have tick. no way i would use mobil 1.

If you are hard pressed to justify something then you are a perfect candidate for whatever you would like to do, part of living in the free world. I'm not sure I have ever seen a 0w40 at costco, but the quality of something depends on the formula, and m1 there are a few formulas. So, whatever formula you see over there look on the label and see what specs are on it.

Mobil 1™ ESP Formula 0W-40​

Is very high quality oil, a "super class" oil, and probably the original super class oil. Built basically as a 5w30 but without the rules, the rules with additives they add are self imposed, not api regs on thin oils. It is dexos 2 which is more important then Chrysler 6.4 spec, but not for a warranty issue, of that I have no comment or opinion, if that is your concern run pup 0w40 that is hemi specific oil. This m1 0w40 is a very high quality product, run it with confidence.

Thank you for the detailed response. I ran by Costco today and they did not have 0W-40, so either I imagined it or they don't carry it.

Very high HTHS. Was not aware of this. Hard to keep up with what manufacturers are doing. I'd need to know the NOACK before I sprang for it. NOACK on PUP & RL 0Ws is low. Too low for me to use in hot summer towing.
