From 5W-20 to 5W-30

[Dirty_white_boy]

I hope your not planning on running 5W-30 from now on. The reason your oil pressure is higher is because your oil pump is working harder to push the heavier oil. This will most certainly lead to premature pump failure in the long run. Also the reason your truck is quite...thicker oil. Not saying you can't run it just saying unless it was accidentally put in go back to what the truck was designed to run...5W20.

Wanted tp post my results going from 5W-20 to 5W-30 W oil. I also did a remote oil filter location after fabricating a bracket, along with a Formato quick drain valve. It drained slower but is cleaner and no tools involved.
I am using a Fram PH8A oil filter. It has a greater capacity the the original molar oil filter that is a little larger than a sewing thimble. The engine took 7 1/2 ouart's of Mobile 1 5W-30 w oil. 20W and 30W are the sam price at Walmart.

Before the change, my oil pressure at idle in park was 38-39 psi. And 51 at speed.
( all this was after engine was at normal operating temperature)
After the change my Idle is 45 psi and 49 in high gear at 60 mph. But when I get on the throttle to move faster the psi climbs to 57-59 psi until I let off or the truck shifts back in to high gear.

I used a Trans adapt remote filter housing and a Canton engine oil filter adapter 22-598 Remote oil filter adapter. It takes any filters that fit 3/4-16 oil Filters. The Engine is as quiet as a Rolex even at start up.

I did this mod because I do not want to encounter the "Hemi Tick" because a the crappy oil pump they used to save production costs. And believe it or not, I cannot find a decent mechanic or shop here in Apopka Florida that is willing to do an oil pump install of the new Meling oil pumps for less than $2,500.00
also I'm getting too old to be tearing down the front of my motor in the driveway. and dodging the HOA spy's.
Hopes this helps some one who's thing about this.

​

My 03 has never developed the tick, at 170,000 I run 5/30 full synthetic high mileage.
Did they go to an inferior oil pump, no one's ever been able to pin point the exact reason for the tick on this forum since I've been here with any validity that I've read? Some get it, some don't, same model years too.

I've been running 5/30 for 100,000 miles now, zero issues. You believe I should go back to 5/20, makes sense, I don't do my own oil changes?

These newer Hemi's have more oil porting and require more oil to be dispersed to the top of your motor. MDS system and VVT . You ever wonder why they rev so high on start up, even on a hot day...this is why. They were designed that way and speced for 5W-20 not to cut down on production cost but so the oil can reach the top of the motor.

I've put a significant amount of research into the Hemi tick and it's still debatable. I'm convinced it's caused by the MDS system shutting down to four cylinders and to be more specific the MDS lifters them selves. I've recently done away with mine and went non MDS lifters and cam. The MDS lifters are designed differently because those cylinders shut down and are prone to failure.

I've also put alot of research into aftermarket pumps...high volume vs high pressure. Not going to get into, you can Google that for yourself. Seeing I had the motor apart I was definitely replacing the pump even at 60,000 miles. After researching it I decided that a new mopar pump was sufficient enough...although I was very disappointed when I got it and saw it was now manufactured in Korea.

The Hemi oil pumps are positive displacement "Gear to gear" pumps from the pictures I've observed. Some other brands of engines come with variable displacement "Vane" in slide design. This type of pump gives the computer yet another way to manage parasitic loads, especially depending on temperature.

So by that logic, the non-MDS 5.7's used a different oil pump......LMAO. Ah no.

5W-20 was chosen for use within MDS and (probably more importantly) to try and eke out as much fuel economy as possible.
All of them rev a little higher upon startup (all the way back to 2003).

It's not MDS; stay off Facebook lol. My buddy's 6.1 car did it, so did my 2003 5.7 Ram. If MDS was the actual culprit, thousands of engines going back to 2005 would have failed en masse but that didn't happen. If MDS was the actual culprit, stick shift car failures would have never happened (news flash, they did) and in MDS engines it would've only ever been cylinders 1, 4, 6 & 7 (news flash, 2, 3, 5 & 8 did as well). The ACTUAL culprit was greed. Cheap out on lifters and this is what you get. A comparison of cut up lifters between the original 6.1, eagle 5.7 and newer 6.2 is quite enlightening when you can see the needle bearings up close & personal.

Temperature and load seem to be the big considerations for choosing the correct oil. MAYBE the engineers who penned the requirements knew what they were/are doing!

Interesting discussion. I have two Dodge 5.7 Hemi trucks, one with 190k miles the other with 250k. Neither truck has the "hemi tick". The one with 190k is a 2009 which I bought new and have kept well-maintained. I've always used 5w-20 Mobil 1. It neither leaks nor burns oil.

I bought the one with 250k, a 2006 1500, a couple of years ago. It was not well-maintained (or even maintained at all) but after a lot of work and a boatload of replacement parts it runs ok but uses about a quart of oil every 1000 miles. I've been using 5w-20 M1 oil in it also.

In my opinion proper maintenance makes a big difference in longevity.

By the way I would never use Pennzoil; it is a paraffin based oil which will leave varnish in the engine. I speak from experience, having once owned a Ford that the previous owner had been using Penzoil in exclusively. Same for Fram oil filters, they have a habit of coming apart and depositing little filter bits throughout the engine.

My hemi tick started on 5w20 at 3500 miles despite a few oil changes early, so I'm pretty sure maintenance didn't have anything to do with it. See oil thread for why EP additives and base oils killed hemi tick and is the only proven thing to do so in some cases even above changing lifters.

Pennzoil is gTl, but if an oil varnishes or not has more to do with if it is synthetic or conventional, see vid below..

So.... when did FCA/Stellantis stop using Pennzoil to make their rebranded Mopar oil?

Anyway, turning wrenches is not an easy job. Like I told my son... Don't be a mechanic. Go in the construction trades. If I was 18 y/o had to do it again... I become a licensed electrician. Much less overhead.

Agreed. My son did listen to me. He's a lineman and makes more than I ever possibly could. I'm afraid of heights, so there's that.

FCA long ago admitted that a change in vendor supplied lifters resulted in quality issues. Sometime in mid-2014 or 2015 a lifter with new hardened, increased needle bearing size was introduced.

So this is from my 2017 Owner's Manual. The way I read it in this book it applies to the 3.6 but not the 5.7 or 6.4

I am not saying 5W30 should, or should not be used.

Then that should have fixed it, which means it was a total lie and nobody should believe what comes from any manu at anytime, EVER. However, I do believe this guy that also jives with forum results when using high performance oils. He just got the additive wrong, but the general idea right, his mistake is AW additives easily wipe off, EP additives plate.

It's from the big 700 page printed manual for my 14.You won't have this manual,as you had to phone to get them,they didn't come with the trucks. Supposedly it's in the big manuals up till somewhere around either 16 or 17
