Safe to idle for 15-20 minutes at a time?

[Jrsweet16]

CONGRATS NICE RIG, i agree man if u got the money for the extra diesel ur wasting do it, i hav never heard anytruck idling all the time n having problems, trial n error buddy do it for a while n monitor it n if problems begin just STOP!!

8% is pretty high, especially for such low mileage.
How many hours?

My oil minder says 75%. Will change oil tomorrow.

Regretfully, I didn't take note of the hours in late may when I last changed the oil.

I didn’t ignore the oil minder on the 2014, I drove for awhile before I quit. My boss believed in that crap. But I don’t care with my own vehicles if it has a oil minder. It’s only a algoretheum based function and does not have a sensor sampling the oil.

It’s an EPA based function to convince you not change your oil sooner. My Vehicles get the oil changed every 5K, even when Toyota recommends at 10K miles. So for years, 7.5K miles was the light duty schedule. Back in the day, before synthetic was introduced through the OEM recommended intervals, it was 3K miles. Regular duty with synthetic oil now in my opinion is 5K miles.

Now if you do a oil sample through Blackstone or equivalent, then I would extend the mileage based on that report.

Glad to hear I'm not the only one changing at 3,000-5,000 mile intervals. Some would call me an obsessive oil changer. But I just supported what I do with a UOA.... Even though I was doing it before the UOA.

This is why I asked about your hours for that OCI. Engine hours are a better determining factor for oil changes than miles, a truck that sees mostly highway miles and long trips will have lower hours on an OCI than a truck that is primarily run in the city or many vocational uses at lower speeds.

If I had to guess, I'd say about 70-80 hours for 3600 miles. June 12- July 3rd we were on a trip from Miami, FL to Asheville, NC. That was a 1700-1800 mile trip that was almost all hwy. Except for some idling at grocery and drug stores while the dogs and girlfriend stayed cool in the truck. And i modified my drive to work to take advantage of I-195 and I-95 so I am taking the hwy to and from work which reduces my idling at stop lights. The new route to and from work is about 5 miles longer. However, I think the many warm-ups from cold is increasing my soot load in the DPF and causing more frequent active regens. I believe the more frequent regens is the source of my fuel diluted oil.

You may want to consider using a quality full synthetic as I do with excellent results going FULL 15k on changes.

I doubt i will ever go 15k on an OCI. I have used the amsoil OE 15w 40 a couple of times in my 5 years of ownership. I do really like the Kendall Super D syn blend.

I get it (kendall.super D) for $18 per gallon including shipping if I buy 6 gallons at a time.

I have a preferred customer membership with amsoil. And I bought some amsoil Dominator 20w-50 in the shed. I used the last of my Kendall Super D yesterday when I changed oil. I also have some redline 15w 40 in the shed that I bought before (before i was aware anyway) that amsoil came out with a new diesel oil. The new amsoil stuff is expensive. Twice as much as the Kendall Super D even with the preferred customer discount. But it being 20w 50, I will be able to run it longer even if diluted with fuel because it starts out thicker.

I was mostly pleased with my low wear metals and low soot content in the UOA.
I realize it was just one UOA, and not too much can be accurately gleaned from a single UOA. I attribute the nonexistent particulates to the amsoil bypass filter. And the low particulate content may have also contributed to the almost nonexistent wear metals. I realize this was a short interval for OCI. And that may also have contributed to low wear metals... And can't be compared to a 15k OCI UOA.

Going to run another sump of Kendall, then try my Amsoil Dominator to see how that resists fuel dilution.

Anyone know what a symptom of a leaky injector would be? And how I approach the dealership to see if they can test for a leaky injector? Would the leak get gradually worse?

I really Don't think it is an injector, tho. It didn't make any oil on our long trip. It only started making oil when driving around town

Your TBN’s are certainly low with your preferred brand when compared to other brands readily available.

The thumbnail is just for you, Ron.

is it possible for those 27000-32000 psi fuel injectors to get plugged or dirty???? thats alot of pressure

I will be changing again at 60k next month and will post my results.
TBN is obviously solid enough to go 17k as Blackstone recommends.

The OEM recommendations are based on average use, I'm willing to bet on the same oil with another truck, it would show poorer results. I have only used OEM, or what the dealer uses. Blackstone sampled at one time early in the trucks life, which showed it to be OK, after 5K miles. But I could have gone further I suppose, but why chance it. Its good that you have gotten good results, but you have to test the oil to be sure.

Why doesn't Blackstone provide an assessment of oil oxidation?

 

[Minnow101]

Some of you guys with these short oil change intervals spend more time under your truck then behind the wheel. Why would the manufacturer provide a 15000 mile oil change if it would lead to engine damage (thus expensive warranty repairs).
I'll maintain mine as directed by Cummins. I think they may just have a tad bit better insight on this. Besides my shed is full enough without having to stockpile cases of motor oil.

I wonder if Cummins (or rather Ram (FCA).... since they warrant the engine as well as the rest of the truck) will actually warranty an engine that has a oil-related failure? They probably decide that on a case-by-case basis.

I used to think $30 for a UOA is a waste of money. You can buy 6 quarts to 2 gallons of synthetic oil or synthetic blend for $30. An oil change can be done for $40-50 including filter.

But I never lambasted anyone for doing their UOA.

I'm actually glad I didn't need to run out and buy oil when I saw my UOA. Glad I checked the oil quality, and glad I had a filter and at least enough oil in the shed to do a quick Friday evening oil change.

I don't need to buy oil for at least a year.
When you live in hurricane country, you find out the hard way to stock a few extra items. Comes in handy if you need to prepare for an evacuation. Got to have fuel. Got to maintain equipment

 

[Minnow101]

I also live in Hurricane country; thanks Florence for 2 years worth of water in 72 hours.

Having a shed full of oil is not what I consider emergency supplies. But to each their own.

After hurricane andrew, things we normally take for granted were hard to get for months on end.
