ENGINE OIL CHANGE

[AH64ID]

AH64ID why did you run 15-40 on current that is "0" and above but on the new 22 you are going to run the below "0" oil. Seems to contradict?

The way I look at it why have a "0" and above option if the below "0" and above is fine?

Not contradicting at all, it’s about the oil specs and understanding what all the specs mean for engine protection.

In my ‘18 I run the same oil you current do, a full synthetic 15w-40 with a -40° pour point. That’s within 5°F of many 5w-40’s, which is plenty and has some benefits over the 5w as well. Since the warm viscosity is the same there is similar protection under hot/heavy operating contortions, but the 15w has a lower NOACK volatility and a better high temp/high sheer rating. That made the 15w-40 full synthetic an easy choice over the 5w-40 full synthetic.

As you know the 15w-40, synthetic or not, is not an approved viscosity for the 19+ trucks. That leaves the 10w-30 vs 5w-40. While the 10w-30 has the better NOACK volatility rating the 5w-40 has a better pour point, better high temp/high sheer ratings, and holds viscosity better when hot. So that makes it an easy decision to run the 5w-40 over the 10w-30.

I was just made aware of Shell Rotella T6 Full Synthetic Multi-Vehicle 5W-30 Diesel Engine Oil, does anyone know if we can use this in the 6.7 its rated CK-4?

There are several 5w-30 CK-4 diesel oils. They should be fine for the application, but if you are still under warranty it wouldn’t hurt to have a conversation with your service advisor.

Interesting. Do they have the same hydraulic lifters?

Well, I finally figured out I could go to AutoTrader for a VIN on whatever year model I'm looking for...

So, this is what Cummins shows for the Valve Tappet on a 2022 Ram:

and this is what it shows on one of our 2022 buses:

That answers my question.

 

[AH64ID]

Interesting, now the 10w-30 recommendation has me curious. Maybe the reduced rpms doesn’t need the same tappet protection.

That answers my question.

That is interesting, makes me think the engine is not the new graphite engine block of the ram. It will need overhead maintenance at some point.

The maintenance schedule....miles, hours and months.

Maintenance Item Miles/Kilometers Hours Months
*Oil and Filter Up to 30,000 mi
48,000 km 1,000 18
Fuel Filter Up to 60,000 mi
24,000 km 2000 18
Crankcase Ventilation Filter Maintenance Free
Overhead Adjustment 150,000 mi
240,000 km 5,000 48
DEF Filter 200,000 mi
320,000 km 6,500
Particulate Filter Cleaning 200,000 mi
320,000 km 6,500
*With a 19 quart oil pan
Maintenance intervals duty cycle dependent
Consult your Operation and Maintenance Manual for more information.

Governor Break on the bus is 2630 RPM vs 3000 RPM on the Ram. The Block is a different part number between the two but the Lifters alone would cause that.

I was also surprised some think $18.33 for DBL/ELF 7349 filter is to much because other brands of filters are cheaper, they don't get that DBL/ELF filters a much better then what the dealer will use....

For the most part, most of us have good maintenance skills, experience, knowledge and use quality products to keep our expensive trucks in top form. I really feel bad when the uninformed have no choice but to have their rig worked on by the uninformed local shop. Local ad on C/L selling a Ford truck with attached repair order so the buyer knows the score, honorable.

Note the price of the oil filter I can't for the life of me figure out what he used In all fairness, the labor bill was very reasonable. His diagnosis, umm.

I was unable to locate T-6 for my truck and tried Amsoil 5w40 syn. Besides being VERY expensive, I am very impressed with it so far. Pressure still up long after the other oil would start dropping. No fill oil yet either.

Did you get ADO or DEO?

Did you pay full retail prices?

OMG $3.31 for a oil filter, that must be one of them high quality made china TP filled oil filters . I was surprised the local dealer only went up less then $5.00 on prices compared to last year, so I was able to get my oil & filter installed and tires rotated fluids topped off for $54.50, I sure as heck did not want to be the one who took off the factory installed oil filter

hmmm... explain to me how the fake oil pressure gauge stays up longer?

Well fake or not, I have noticed that the fake pressure seems to stay up or at 51 PSI many more miles later then the T-6 did. The T-6 after 2-3K would not go to fake 51 PSI unless higher rpms.

Unfortunately if you are relying on the OEM gauge there is no difference.

That being said, when I switched from AME to DME the DME ran cooler and held pressure better. I did run aftermarket oil temp and psi gauges.

I think when you get your '22, you will see that the fake oil pressure/oil temp gauges are more real than you say. Kinda like a smart phone. I think there are so many parameters used, that they are almost real. They satisfy me.

They are pretty good in the ‘18, and do a fairly good job compared to the aftermarket gauges I had in the ‘05.

They are still 100% fake and absolutely no reason to even look at them, they tell you nothing. To me there is no way to be satisfied with that, so I just accept that we don’t need them and a check gauges light will tell me something is wrong.

The book says if you have abnormally high or low oil pressure to check it out. Same with high oil temp, check it out. It don't say they are fake and just ignore them. For you to harp on this is a disservice to Ram and owners alike.

No, the disservice is from Ram. The verbiage in the owners manual is contradictory to what’s installed on the engine. You will not ever see abnormally high or low pressure readings, you will either see a fake “normal” reading or no pressure (less than 6psi for 30 seconds).

There is no oil pressure sensor, and there is no oil temp sensor. If you pay attention to either “gauge” on the dash then good for you, but nothing factual is being displayed. The data on the dash is 100% fake and algorithm based. It’s there to make you feel good, not to provide you with anything useful.

It’s there to appease owners who don’t know any better. It’s pretty sad for Ram/Dodge to do this, but it’s been that way for over 20 years.

 

[NIsaacs]

If you pay attention to either “gauge” on the dash then good for you, but nothing factual is being displayed.

The oil temp reads ambient, in the winter or summer, matches the transmission temp and coolant temp. I call that factual.

You are convinced and I am convinced, so we are both happy. I think with your '22 you might bend some if you watch them at all. If you don't, then yes, they will be the same as your '05 and '18.

 

[AH64ID]

Sure it reads ambient after sitting, it’s how it’s programmed.

It doesn’t matter how well they program it, there isn’t an oil temp sensor on the block, so the data is useless.

One of the things I'm looking forward to about the '22 is that the oil psi gauge isn't permanent and doesn't have to be selected. It won't be displayed for me, I'll put some relevant information up.
