Synthetic Oil

[GottaBeKD]

Is milk oil soluble? Might have some compatibility problems, but I hear it does a body good.

Imagine what a catch can dump would look like...

Speaking of catch can... is there any difference in the 18 5.7 for catch can mounting. Why do some not like 18 as compatible???

^^^^^

If that isn't a perfect oil additive for what it does, I don't know what is.

I wonder if you can drink bgmoa in a pinch?

Have a slippery weekend boys

For those of you running a thicker oil viscosity in you 5.7 Hemi, see clearances for the Cam and bearings below. For those of you running a ?w40 weight oil in the 5.7 4th Gen Hemi, think again!



Chrysler Material Standard MS-6395 CAMSHAFT SPECIFICATIONS DESCRIPTION / SPECIFICATION 5.7 4th Gen Hemi. Recommended Engine Oil - MOPAR API Certified SAE 5W-20 engine oil.



Bearing To Journal Clearance Standard - No. 1 / .0015 - .003 in.



Bearing To Journal Clearance Standard - No. 2 / .0019 - .0035 in.



Bearing To Journal Clearance Standard - No. 3 / .0015 - .003 in.



Bearing To Journal Clearance Standard - No. 4 / .0019 - .0035 in.



Bearing To Journal Clearance Standard - No. 5 / .0015 - .003 in.



Average width of a Human Hair = 0.001 – 0.005 in.



Note: Clearances are per Chrysler.



WHY IS THIS IMPORTANT? Because internal engine components are cooled by oil “Directly” and cooled by the coolant “Indirectly”. So running a thicker oil than what is recommended is a bad idea in most cases. Because oil “flow” through internal engine clearances is critical for proper lubrication and to pull heat from internal engine components. The engine oil temperature in these areas of the engine can be 50-90 degrees “Hotter” than oil sump temperatures; thinner oils flow better than thicker oils pulling more heat from internal engine components.

Another goodie.

Another way your lubricant could be losing its viscosity is through the loss or shear down of the viscosity-index (VI) improver. For example, if you are using a multi-grade SAE gear or engine oil such as a 10W-30, this oil contains an additive known as a viscosity-index improver. During use, the VI improvers can sheer down and break apart, causing the viscosity of the oil to decrease. Remember, exposure to high heat is the biggest factor in causing the sheer of the viscosity-index improver.

Thus is why hths is needed to see the quality of the base oil. You guys running heavy Vii formulas, you are actually running the next weight down, you just don't know it.

 

[Burla]

What is the % of Vii's in any giving oil? These molecules are larger then their dense brothers (base oil), and unstable. When they are denatured, your lubrication is less protective. This is why the big oil companies use as little as they can get away with.

And, as far as we know, Redline has basically the best base and lowest vii's, right?

Annnnd... let the RL infomercial commence...

 

[Burla]

For fact we only know 5w20 and 10w30 redline doesn't have any. Esters/Pao have natural cold flow properties so Vii's aren't as necessary, in fact correct me if I'm wrong Kyle, Dave from redline said their 5w30 had minimal vii's. I can't say for sure other weights have less then other brands. And there are a few other redline type companies out there like Millers and Motul and I'm sure others, and more pao companies floating around.

200 mile update on new formula SS 5w30. My Hemi was nice and quiet on a 28* cold start this morning and no ticking when the oil hit 200*. Looks like the added moly is working[emoji106]

 

[chrisbh17]

Update on my 600 mile old 5W-20 synthetic (from the dealer): MDS dis-engagement is no longer nearly as smooth as it used to be. My hot, in-drive at idle oil pressure is now 34-36psi.

Seriously considering swapping it out this weekend for QSUD 5W-30/5W-20 mix and an RP filter.

RL 4qts 10w30 and 3qts 5w30 after 25 mile drive home from work.

Your oil pressure should be higher, if anything, as you go deeper into your OCI because oils get a bit thicker with use. Initially it will thin out some because the VIIs break down quickly, then thicken as more and more contaminants are suspended.

If you mean me thats right on par for my truck at full temp at idle.

 

[chrisbh17]

The factory fill didnt exhibit any increase in pressure...granted it was only in there for 2K miles but it didnt change along the way.

As good as PYB is supposed to be, Im not really a fan of it so far in my Hemi. I think the factory fill performed better even at 2K miles (I believe the factory fill is Pennzoil Gold, a synth blend?)

EDIT: my problem with 34-36 psi at idle is my gut tells me the lubrication flow in the Hemi is complex enough that lower pressure contributes to wiping out the cam/lifters. Its just a hunch, but I feel strongly the higher the pressure the more the oil will get to where it really needs to be.

Okay, and the base oil? Basically the best, right? Top 3? Top 5 for sure, right?

So best is a taboo statement, too many people get all but hurt and want to fight if you use the word best. And then best at what? It is not the longest oil change interval oil, it doesn't produce the best wear numbers, but it does seam to quiet better then others. So best is for each user to choose imo. Obviously I use it, so I much use it for a reason

Myself I dont feel 34/36psi is low at all.
If it were down to 15/20psi then I would feel that it was low.

I remember my stock SB Chevy carrying 15psi at idle with never a thought or problem. lol
