Bad lifter To end a bad summer

justintyme01 · Sep 11, 2019

I just got back from picking my truck up. They said everything sounded normal and my lifters do make noise but not an excessive amount or for a prolonged period of time. I talked to a tech that listened to the truck when they started it this morning and showed him the video I took. He said it definitely did not sound like that when they started it and offered to keep it longer or I could bring it back if it becomes more consistent.

Anybody and everybody that has a 2009 or newer 5.7 Hemi should at least be running 5W30 at a minimum. I hear people all the time talking about switching to synthetic but they rarely ever move up from the 5W20. PYB 5W30 will be less noisy than either PP or PUP 5W20 at startup. 5W20 is just too thin. Switching to synthetic is not going to fix the problem it might just make it less frequent. If you absolutely feel like you got to run 5W20 at least use Redline or Amsoil. I've been running Redline 5W30 for roughly 13-14K miles and I've only heard that sound one time and that was after shutting it off and restarting it like 5 seconds later. Anybody who goes to the dealer for Hemi tick is probably just wasting their time.

I'm running 5w20 Mobil1 in my 2013Charger 5.7, 123k miles and just got back stellar oil analysis results.
I have MDS disabled and don't miss it.
I just may go to 5w30 next. Thanks

@WhiteStar, have you swapped oil filters yet?

Haas · Sep 12, 2019

Most mechanics will tell you, don't deviate from the weight of oil, that the manual states. They claim engines are designed to have a very specific amount of oil flow throughout the engine, and changing viscosity (weight) will change the oil flow.

I think if I had a hemi that was not ticking, I'd be sticking with the manufacturers recommended oil weight.

The only problem is that the government and cafe standards are involved now. It's no longer about longevity, it's about gaining another 2% in fuel economy

Thanks for the food for thought.

Yeah, but deviate from manufacturers recommendations, and see how quickly your warranty gets invalidated.

I think it has more to do with design, pressure, and volume than it does fuel economy. If they need to squeak better economy out of it, I think there are a lot more places to look than advising thin oil. They know if they start advising oil that's too thin, they could have a **** storm on their hands with early failures.

Food for thought for you.The 5.7's in the Challengers with a manual transmission call for 5W-30,same exact engine as the trucks,but with no MDS.Using your analogy about the manufacture's building the engines to tight tolerances,that must mean the stick cars are built looser,lol.I don't think the engines are built any looser,it's just one has MDS the other doesn't.BTW the mds will still work with 5W-30 it might be a touch more noticeable when it kicks in if you have an aftermarket exhaust,but still kicks in

Except FCA had to revise the oil specs for the ecodiesel due to the oil being too thin. If you look at European specs, same engines, the use thicker oil. EPA has a lot to do with oil weights.

I'm just throwing it out there. It's what I hear from mechanics when I ask. Take it for what it's worth.

Not sure what you mean in your first sentence? FCA doesn't have ecoboost, that's ford. If you're saying that Ford had advised too thin of an oil when they first came out with the ecoboost, and then went to a thicker oil, then I get what you're saying.

Sorry meant ecodiesel. Yes, they had to revise the oil specs to a heavier grade.

I see.

Just for ***** and giggles I dug out my 700pg owners manual. On page 677 are the recommended oil weights for the 1500.Mopar 5W-20 /Penzoil are the recommended oils,but in a paragraph right under that,it also says 5W-30 oil approved to Fiat 9.55535-S1 or Fiat 9.55535-S3 maybe used when SAE 5W-20 oil meeting MS-6395 is not available.It looks like 5W-30 is an acceptable substitute if 5W-20 isn't available. Hey Burla what in hell do those spec numbers mean you old oil guru,lol I'll start another thread on how to get the big owners manuals free from FCA,up in the General Discussion area.

I have to say, that is the first time I ever saw an owners manual recommend an actual brand.

It also says Shell Helix to,lol.Give me a minute or 2 and i'll give you the phone numbers to call to get the big manauls "free" from FCA.

I don't even know what "shell helix" is. LOL

Nevermind, I googled it

Yep, a Wix XP and Shell Gas Truck 5W-20 at 3000 miles. Didn't make a difference as this video shows with 1,600 since the oil change
Keep in mind this is the day after bring it home from the dealer who said unable to duplicate.
