Iron still artificial from added iron to fuel, so won't really be able to tell anything about the iron for another OCI or two. But trending in right direction.

My 2 cents.


I only used the Better Diesel FBC additive for about half this OCI. And on the OCI before this one, I wasn't using it at all. It is a little curious that Iron wear rate was lower in this UOA, despite the use of the FBC, but Iron wear isn't the thing that's worrying me now. I'm going to continue using the fuel additive to keep the DPF clean, so I'll just assume that part of the Iron reading is coming from the FBC.


On iron content, my guess would be less overnight idling in freezing temperatures menas less fuel dilution and thus less iron in the oil from the fuel.

Also, not sure but iron may also act as an antioxidant.

rather an oxidant I think... PSA uses an additive in the diesel fuel (added automatically after fueling up) to reduce the temperature for soot to burn. The latest generation uses iron in a liquid molecule. Apparently reduces the burn temp by 100C.

Better Diesel FBC will alter your Fe rates; it will skew the Fe in a UOA because it uses Fe to improve the soot burn-off in the DPF (or something like that). It will also have the propensity to alter oxidation. I cannot discuss the chemistry; beyond my skill set, but I accept it for what it is. This FBC phenomenon has been discussed before.

We really cannot compare this UOA to others without additives; not the same apple in the basket of oranges.

The act of preventative maintenance, in and of itself, is FAR MORE important than brand/grade/base choices among lubes and filters.
- under maintaining something is akin to abuse/neglect; that can kill equipment by shortening the lifespan
- over maintaining something has never been proven to be anything but a waste of time and money

This has my curiousity. The oil thickening seems excessive for the miles on this oil. I wonder how many hours are on these runs. OP. Have you been tracking hours at all?

My truck doesn't have an hourmeter, at least that I have been able to find in the information menu. New trucks I know have a total hours run and idle hours readouts on the vehicle information display. But my truck is a 2008.

Going by my logged hours and miles, I average 60 mph, so for the 14,500 miles of this OCI, it would be about 240 hours. Then there is idle hours, which I can only generalize about. When I am hooking up to a trailer and doing pre-trip inspection in the yard, it is about 45 minutes of idling. As long the weather is not too hot or cold, I idle the engine about 30-45 minutes on an overnight. If the weather is too hot, I run the A/C to be comfortable. If the weather is too cold, I run the heater to be comfortable.

The people at Better Diesel seem to be very in touch with their customers. I get e-mails from Jane Gates, who is the inventor of the FBC, with updates on new products and promotions from Better Diesel. I think I will e-mail her my UOA results, and ask if the additive can promote oxidation of the oil.

Mr. Harman per the manual:

NOTE: There is also an engine hour function. This
indicates the total number of hours the engine has been
running. To display the engine hours perform the following:
Place the ignition in RUN, but do not start the
engine. With the odometer value displayed, hold the trip
button down for a period of 6 seconds. The odometer will
change to trip value first, then it will display the engine
hour value. The engine hours will be displayed for a
period of 30 seconds until the ignition is turned off or the
engine is started.

Thank you for the tip. I didn't get a manual with the truck. I should get one.

Most welcome Sir, My Pleasure. Below is a good link from carbonite Cummins for quite a bit of information as well.

http://www.carbonitecummins.com/articles.html

Cant seem to attach PDF of owners manual in here, But I have it if you want me to email it to you. Just pm info if you would like.

Put the truck in my local diesel specialist's shop to check out the EGR system. He ran a scan, and found there was a code for High Crankcase Pressure. He says the crankcase vent filter is clogged. Maybe that is contributing to oil oxidation.

There is also a code for Low EGR Valve voltage, and they are checking that out.
Also will inspect the EGR cooler for leaks.

What Cummins' OCI for that little engine? The Heavy Duty Engines were at 15k, now maybe 20k OCI's.

Then again, the HD engine sumps are 4 x the capacity for only 2 x the displacement. So the "B" series is really working with far less reserve oil capacity than the "X" (N).

For a 2008 6.7 intervals are 7500 miles or 6 months.

I just checked the hourmeter: 3756 hours
Odometer is 222,470 miles.
Average lifetime speed is 59.2 mph

Wow, that's short. Is the sump still 3 gallons? Then again, the Cummins ISB engine is 6.7L displacement w/ 3 gals. oil = 2.23L displacement per 1 gal. oil
Cummins ISX engine is 15L displacement with 12 gals. oil = 1.25L displacement per 1 gal. oil.

The ratio is 1.25 / 2.23, or 56% less mileage OCI based on engine size vs. oil sump size. 7,500 miles / 0.56 = 13,400 miles. Close enough to 15,000 mile OCI for the ISX. I guess that makes sense in that most Class 8 tractors get more miles per year than most diesel pickups. Otherwise they'd have to offer a 6 gallon sump for the ISB6.7L engine.
