Herdin' turds ain't my thing, but I did enjoy farm work when helping buddies, even running the manure spreader.

I worked in an office for a year, I'd rather die then do that again, I'll collect terds all day long so long as I don't have to work in an office.

Thank goodness I've never had a stinkin' desk job! Always been on my feet.

Thanks @Burla

Unfortunately the 3rd brake light leaked again at 82k. Fixed under warantee a year and a half ago at 35,900 hope this is the last

I just sealed mine off with RV roof seal tape. Crazy durable stuff.

you must have found my thread, that looks perfect. Mine hasnt leaked now since I fixed it, sad the dealer just doesnt use that stuff instead of poor oem gasket.

you mean from the outside? If you ever want to do it from inside most ram forum guys like that stuff travis and myself used. this thread.

Yeah, exterior roof sealant tape. Since I have a small camper I already had the stuff on hand for emergency use.

yep i found it! A great thread! I was excited to go wash the truck yesterday since we hit 30 degrees but driving home from work i turned around to see my headliner wet again. My old gasket actually looked good visually. It made me nervous what could be leaking considering it looked so good but then i squeezed it and water was seeping from the gasket. I wonder if this has been addressed in the 5th gens? Imagine paying 80k for a limited 5th gen and having this happen

Looks like sale price of 38.36 for

Red Line 5W30 Motor Oil Gallon 15305​

As posted in oil filter thread, this happens with the smaller oil filter in rams 2013 and up. Begs the question, how much research did fca do when they changed from the 20-820 size filter to the 10-48 smaller filter? You know what I think, lol. Use the larger filter always, or by all means use the smaller paper filter that will go into bypass 24/7 when it stiffens. I also wonder if this has happened with the smaller mopar filter, but how much do you want to bet they would never admit that one? Exactly what in the 10-48 or it's amsoil clone is built so much worse then the smaller mopar filter as far as flow goes? See oil filter thread on which amsoil filter works and which amsoil filter has this issue, the clone of RP are posted in this post. The more we read and the more things change, it always comes back to 20-820 RP filters are a pretty good strategy imo.

 

[Burla]

In oil filter thread it has amsoil's statement, which include the years that were effected. Conveniently Stephan's Mopar Bulletin omits that tiny little detail, lol. Yeah, it has everything to do with Mopar going to a smaller filter, see Amsoils statement on it. Free cookie if anyone can find royal purple's statement on this if it exists.

That's why I'm stocking up on the 20-820's... 10 so far...and more on the way! (and I got the tube of silicone grease to boot as you suggested for the gaskets)

check out oil filter thread, real good info in there just posted. Fram Ultra looks great and so does RP.

 

[HEMIMANN]

I just bought a RP 20-500 for spring oil change. I'll have to look at my notes on media size if I want to put bigger Fram on - my heavy duty frame and 6.4L Hemi allows longer filters, but no wider than the mini-me's they put on at the factory.

If memory serves, the longer Fram wasn't much longer, and the big diameter XG2 won't fit - lower coolant hose is right there.

I’m at a bit of a quandary with my 2019 classic Hemi. At 33,000 miles I changed oil with Royal Purple 5w30 and an RP filter. This was the result:


About 3,000 miles later the oil pressure slowly dropped fro 48 psi to 42 and even 41 psi at times:



Certainly I checked the oil level and outside temp was 20 degrees colder with the lower pressure.

Many folks say that hiway pressure is over 50 psi….I’ve never seen that.

It concerns me that psi dropped 7-8 pounds over a 300 mile run with oil the only has 3,000 miles on it.

Any ideas?? Oil break down? Pressure sensor going bad? Engine about to grenade?

As far as i know oil viscosity shouldnt have an impact on oil pressure at highway speeds as the oil pump adjusrs to get 50-53 psi at highway speeds. Hope i got that right if not someone please correct me and call me a dumb a s s

My oil pressure at highway speeds are the same with pennzoil platinum 5w20, schaeffers 5w20, and mobil 1 euro 0w40 which is 50-53 psi. My hot idle oil pressure is where its different. Consistently 40-42 psi at hot idle with the 0w40 mobil 1 where as the 5w20 oils i was at 33-36 psi

 

[runamuck]

mobil one in all my stuff for many years..no reason to change

Change the oil and filter. My bet is on the filter. There are plenty of good filters to choose from. I run FRAM FS2, you can find it at Advance Auto Parts. Probably the best bang for the buck considering it has awesome flow and filters 99% at 20 microns.

Royal Purple oil is just generic Lubrizol cookie-cutter stuff these days, their API-certified line that is. It's about as good as Super Tech if that.

Just pick any major brand. You're under warranty, so I would go with Mobil 1 Extended Performance 5W-20, Pennzoil Ultra Platinum 5W-20, or Pennzoil Platinum 5W-20. Actually, Pennzoil Platinum 5W-20 is the exact oil as Shell Helix Ultra SP 5W-20 sold everywhere in the world: https://www.shell-livedocs.com/data/published/en/b7484a5f-80ad-43b8-967f-ed0c90532bb3.pdf

Shell rebadges their Shell Helix lubes as Pennzoil and Quaker State in the US, and it's good stuff.

Valvoline Extended Protection 5W-20 is also very good stuff.

If you want something with Euro approvals that provides the best anti-wear protection, Castrol EDGE Extended Performance 0W-20 fits the bill as it's MB 229.71 approved.

Bellow you can see how your average API SP oil compares to an MB229.71 approved lubricant.

Best of luck and let us know if your oil pressure changes.
