So about that Penzoil…

[Marksman]

What dummy uses an air gun on an oil plug. I did on a car once, lesson learned.

The same dummies that tighten the oil filter so tight that you have to ram a screwdriver through the body of the filter it to get it off when both types of oil filter wrenches fail.

Unfortunately, I’ve seen that more than once myself.

This 392 owner used Mobil 1:

And guys at WFO Concepts did the topping off with Pennzoil SRT:

These manufactures just love coming up with new viscosity formulations it seems…

My daughter‘s 2020 Toyota RAV4 uses 0W-16 motor oil. Really, 0W-16…

0W-15 and 0W-20 just weren’t sufficient I guess…

Motor oil requirements are pretty much dictated by the manufacturers and are supposedly based on their engineering departments recommendations.

Couldn’t find this addressed anywhere else, so if it has been, please direct me to the appropriate thread.

I’ve heard that the 392 comes from the factory with Penzoil Ultra Platinum in the crankcase. Just wondering if anyone knows the actual difference between the “Ultra Platinum” and the “Platinum Euro”? Both are offered in 0W-40.

I’ve never been a big fan of Penzoil motor oils in general. Any thoughts?

Higher up in this thread is a post with a link to an article that is not very clear about the differences except when it comes to the viscosities availalbe. I do know that the Ultra Platinum is available in Quart bottles and the Platinum Euro is available in Liter Bottles which I think is the biggest difference between the two.

No dealer oil change is free…. My first of 3 “free” oil changes on my dodge truck cost me the oil pan as they air ratcheted the plug through the pan and had to pull the engine to replace the pan…. That was the last “free” oil change I ever got.

Both times I took my TrackHawk in for the Jeep Wave oil changes I got it back one quart overfull. The service departments swore up and down that they only refilled the engine with the 8.3 quarts listed as the engine oil capacitiy. When I asked how they drained the oil cooler they looked at me like I was crazy and said the oil cooler drains with the rest of the oil. Uh, no it doesn't and if they did want to drain the oil cooler they would need to remove the front bumper to get to it. So much for Dealership expertise.

I ended up buying the Pennzoil Ultra Platinum in the 6-quart packs I found on Amazon. I’ll use this unless I find a compelling reason not to.

But I agree that the Pennzoil formulations are likely almost identical.

The bigger (and likely more difficult to answer) question is whether the Pennzoil product is equal or superior to a similar product from Mobil-1, etc.

It’s probably academic, as I will go with what Jeep recommends unless I have a good reason not to.

You may want to take a look at what AMSOIL has to offer. AMSOIL was the first to manufacture fully synthetic motor oil for use in Automobiles/Trucks etc., in 1972 from natural gas and the process has been copied by other brand name oil companies since then. AMSOIL is superior to Penzoil and Mobile 1 in all respects. You can obtain a free AMSOIL catalog using this link https://www.amsoil.com/w/InformationRequest.aspx?type=catalog and please enter 506808 as the referral number towards the bottom of the request next to the question mark. Should anyone care to obtain any of the products contained in the catalog at a 25% discount please let me know and I can point you to the link to register and walk you through the process.

I’ve always heard nothing but good things about AMSOIL products, and while expensive, they are likely well worth it, especially in high performance engines.

I’m sure that their comparable product probably meets and exceeds all specifications required by Mopar, so I don’t see how there would/could ever be any warranty issues.

Granted the retail prices of the AMSOIL Products is high compared to similar products but AMSOIL preferred customers enjoy purchasing their products at 25% below the retail prices which makes them extremely competitive. AMSOIL also guarantees that their products meet or exceed manufacturer's requirements and back it up with a very thorough written guarantee.

Near as all my research has found there is only 3 0w-40 oils that has paid the money to be ms-12633 certified, Pennzoil, Valvoline and Schaffer. There are others that meet or exceed but are not certified, amsoil, redline and ravenol.

It also looks like the valvoline isn’t available anymore.

A forth 0W40 Motor Oil can be added to the Chrysler MS-12633 Certified club, check out the photos of the 0W40 Amsoil Bottle labels.

This was discussed on another hemi forum. Amsoil says it is recommended but it is not certified. I am not an oil zealot so run what you want. But just passing on info.

The label on the back of the bottle contains the the certifications that apply to the 0W40 AMSOIL product and one of them is MS-12633 among others.

Why does FCA put the oil change interval on a 6 month timeline? What happens to fully synthetic oil over the course of 6 months??

I'd say absolutely nothing happens in 6 months. In general, when people ask about using older oil its all about what certifications it has rather than how old it is. Oil does not deteriorate. Not sure how I will handle this as I am sure there will be 6 month periods that I dont put 5000 miles on my 392. 5000 miles is my planned maintenance interval.

I'm glad I'm not the only one questioning this. The 392 will be a third vehicle for us and used as nothing more than a toy and something to pull behind the RV. If it sees 1500 miles every 6 months I will be surprised. I know oil and filters are cheap compared to the price of a 392 and warranty could be affected by not following their ridiculous timeline so I will follow the schedule but what a crock.

The only thing that happens to vehicle sitting is that the engine “breathes” with hot and cold cycles just like a vented tank does. This can result in water from condensation getting the oil. This is boiled off in driving.
Probably negligible unless parked in sun in humid climate where it experiences wide temp swings and is not driven frequently.
Even then nothing magic about 392 that would require 6m interval. Probably would be fine with 1y/10k like our land cruiser.
Having said all that I’ll change it every 6k miles. I’ll be driving out enough to hit miles before time

 

[YukonCornelius]

Pretty sure it’s just an average… average annual mileage driven is 15,000 (slightly less) according to NHTSA. Six months is 7500 miles which happens to be what the standard change for synthetic is (although many say 10k is fine, 7500 is still the recommended average.)

still, for the first oil change, I’d still cut the in a third or less per some of my other posts…

One thing to keep in mind is that short trips of 10 mles or less do not give the engine enough time to warm up sufficiently to burn off the moisture that may have accumalated in the oil and the inside surfaces of the engine.
