Synthetic Oil

[chrisbh17]

As for hot and cold, when oils are cold they protect well obviously huge film strength, but when they are warm is when oils additives or base oils can have a play in lubrication. Vii's need heat to do their magic, the issue with those being in a ticking condition they will shear away with use I'm curious Chris if your issue sounds the same with a fresh oil change as it does well into your interval?

I think it might be a touch quieter now, the current oil has about 2K miles on it. I know PUP has a lot of cleaning capability (like Redline) so maybe it cleaned away whatever was there keeping it quiet and is now plating better? Im still not happy with it, though. Its also still possible that the noise I hear under acceleration has nothing to do with the engine (or at least not anything to do with the engine that oil could fix). But I find it interesting that others have had the same experience...after first oil change all of a sudden the engine is noisier. So what was so different about the factory fill?

I think there is something to the theory that an engine made for 20 weight (hear me out) shouldnt necessarily be run with 30 weight. I do think oil passages, etc are designed for a viscosity and stretching that number could possibly make for issues. PUP 5-30 is pretty light as 30 weights go, but Redline is pretty heavy. Could I mix RL 5-20 and 5-30? Sure, but from all the experience here it seems that straight 5-30 RL is the key.

Like you have mentioned before, we cant quite say for sure what makes the engine quiet. Can add enough additive to bring moly up to RL levels but it doesnt necessarily work. Can try a high PAO oil but there arent very many of them around (thats why I mentioned Mobil 1 EP 0W-20 a couple weeks ago). What else is there to try? It sure would be nice to know for sure what is making the engines quieter. Maybe its just the heavier weight of the RL....but if it is that, are we "fixing" anything or just masking it with heavier oil?

You have been around long enough to know that should get better overtime. How many miles on the truck? You have only a few oci's in memory serves me, you should be gold.

Creeping up on 28K miles. If it stays quiet, I am done experimenting, and will stick with it.

OMW2Ski Lucas stabilizer has a operating temp viscosity like 4 times thicker then the thickest gear fluid we use 75w140, if there is anything that "can" possibly void a warranty that would be it. m1 not getting the hemi spec was purely political on their part, payback for FCA giving a 2 year monopoly on the spec to Pennzoil. Anyhow, if you are spec hunting just find another oil that has the spec, I think there are a couple. The GtL base oils seam to be a little louder then the group 3 stuff, it is a common issue here. Find a group 3 oil with the spec that is a little quieter, you will be good.

Ravenol Chris would be an oil with pao that goes to the lower visc, I believe I saw one of their offerings anyhow.

This sounds great?

For the developement of RAVENOL DXG SAE 5W-30 the proven formulation of tri-nuclear molybdenum, tungsten and OFM (Organic Friction Modifiers) was used. A highly polar Group V base oil was used in this formula, which has good compatibility with the PAO used.

Operating visc 10.7.

Yeah I stumbled on that. And on top of it all it even has the Chrysler certification.

Problem is its expensive (even more than RedLine) and not nearly as easy to find as RL.

 

[Burla]

You mean the people that use the most expensive base oils actually want more for their product? The nerve.

It sounds like you found a strategy that works for you, live with a little noise and hope it works out. Many people have hemi tick and get a lot of miles from the engine.

Too early to draw conclusions, but at @ 550 miles into my Redline experiment my 6.4 has never been quieter. Cold starts have been clatter-free, and my hot tick is just about gone. I have to stand by the fender and listen a bit to pick it up now. So far, so good.

You said you’re running 5W 40 correct?

Sorry,

But expensive things carry the expensive cost over to the customers frequently.

But you get what ya pay for

True.

I should rephrase...its about the same cost as Redline but a lot harder to get. Blauparts.com seems to be the best place (they sell on Ebay too)

For the cost its a pretty big gamble vs RL which we know already works.

I've been running Red Line 5w30 with a RP 10-48 filter now for about 6000 miles. I can't say the tick has gone away completely. It has not. But it's certainly not as bad.

My truck only has 13,500 miles on it.

Someone on the Z forum mentioned their tick quieted a lot when they went to an M1 filter (changed oil too but used the same oil as they usually did)

Not sure where the M1 filter falls in the range of good/bad.

I would categorize that as a fail, I would keep looking for something that works. Now the dealer really wont help, lol. Next time go back to PUP and let it get louder and see if dealer will address it? Did they not want to fix it in the first place?

If is part spun microglass and finished in 4th place on that oi, filter test. I doubt there is any better flow then a RP, but it certainly doesn't hurt to try. As noted I had bad luck with a puro syn filter, it was the only time I had hemi tick with my 5w20 and 5w30 usage other then the 500 miles it took for my tick to disappear in the first place. That filter was on my truck for a couple days, went back to RP, tick was gone. Still have another puro syn filter, I think maybe someday I will do a flush and use it up like that. Some filters will make engines tick whereas others wont, it is a consideration in the strategy imo.

 

[chrisbh17]

Yeah now that I think more about it, I wonder if a filter could cause an engine tick *while driving*. If the ADBV fails then there would be a tick at startup, but once driving the only thing that should cause a tick would be a restriction, yes?

Im on my second RP filter (first was the 20-820, now the 10-48) and it still ticked the same. The chances of getting 2 RP filters that would cause an issue are probably pretty low, so unless its the design of the RP filter causing the issue, another filter probably wouldnt affect my noise.

I'm running 5/30 redline with Fram ultra filter, quiet, smoothe, and no tics. I've got a couple Purolator boss's and an Amsoil filter on the shelf but hesitant about trying a different combination just to see if it works, might just keep using the Fram ultra's.

I traced the reason for the puro's and why I believed it ticked in my truck, not enough holes for full flow. I could have cared less to look into this until my truck ticked on one of these filters, a pic is worth a 1,000 words. We have been researching a listening to youtubes and research, there is nothing I've heard in the last 5 years that convinces me there is a better filter then RP. I've never heard anyone having an empty filter when changing oil, adbv is not an issue at all with hemi's, as in zero, never happened. They never keep oil in the lines, only the filter, and they work.

M1 oil filter is my Old Faithful filter, I called and spoke with an M1 representative and they stated the M1-113A flows 18 Gallons per minute. Not sure how that compares to the full synthetic oil filter but still notable. I also like the gasket better than all the others, it's thicker and more spongy. Crushes down and flattens against the engine block very well.

I wouldn't hesitate to use the amsoil ea filter. I would toss the Purolator.
