I was wondering what Cummins recommends on the Cummins 8.9 425HP mileage for the first oil change.

I am not sure but I use the following schedule for all my filter changes.

oil & filter: = 6000 miles or 12 months

fuel filters: = 10000 miles

air filter: = based on my indicator

coolant filter: = 12 months or at ea. oil/filter change (dep. on testing)

I hope this helps. This regimen has served me well for over 29 years (that I have been performing these changes myself).

From the Cummins Quickserve site for my C8.3 engine:

General Information:

Perform maintenance at whichever interval occurs first. At each scheduled maintenance interval, perform all previous checks that are due for scheduled maintenance.

Maintenance Procedures at Daily Interval

Drive Belts - Check
Coolant Level - Check
Cooling Fan - check
Lubricating Oil Level - Check
Fuel-Water Separator - Drain
Maintenance Procedures at 10,000 Kilometers [6000 miles], 250 Hours, or 3 Months

Air Cleaner Restriction - Maintenance Check
Charge Air Cooler - Maintenance Check
Charge Air Piping - Maintenance Check
Lubricating Oil and Filters - Replace
Air Intake Piping - Maintenance Check
Air Compressor - Maintenance Check
Maintenance Procedures at 19,000 Kilometers [12,000 miles], 500 Hours, or 6 Months

Coolant Filter - Replace
Supplemental Coolant Additive (SCA) and Antifreeze - Maintenance Check
Cooling System - Maintenance Check
Fuel Filter (Spin-On Type) - Replace
Maintenance Procedures at 38,000 Kilometers [24,000 miles], 1000 Hours, or 1 Year

Cooling Fan Belt Tensioner - Maintenance Check
Overhead Set - adjust
Drive Belts - Maintenance Check
Maintenance Procedures at 77,000 Kilometers [48,000 miles], 2000 Hours, or 2 Years

Air Compressor Discharge Lines - Maintenance Check
Cooling System - Inspect
Vibration Damper, Rubber - Inspect
Vibration Damper, Viscous - Inspect

NOTE:
The lubricating oil and lubricating oil filter interval can be adjusted based on fuel consumption, gross vehicle weight, and idle time. Refer to Oil Drain Intervals in this section.

Test the SCA concentration level every 6 months unless concentration is over three units; then check at every oil drain interval until concentration is below three units.
Antifreeze check interval is every oil change or 19,000 km [12,000 mi], 500 hours or 6 months, whichever occurs first. The operator must use a heavy-duty year-round antifreeze that meets the chemical composition of GM6038M. The antifreeze change interval is 2 years or 77,000 km [48,000 mi], whichever occurs first. Antifreeze is essential for freeze, overheat, and corrosion protection.

Follow the manufacturer's recommended maintenance procedures for the starter, alternator, generator, batteries, electrical components, engine brakes, exhaust brake, charge air cooler, air compressor, air conditioner compressor, and fan clutch. Refer to Section M for addresses and telephone numbers.

Oil Drain Intervals:

Refer to the following flowchart to determine the maximum recommended oil change and filter change intervals in kilometers / miles / hours / months, whichever comes first.

Is the vehicle one of those listed below?

Truck crane/yard spotter
Paver/crane/backhoe
Dozer/scrape/skipper

If Yes - select the correct oil drain interval from Table 1.

If No - is the vehicle one of those listed below?

Tractor/combine/irrigation equipment
Genset/air compressor/fire equipment

If Yes - select the correct oil drain interval from Table 2.

If No - select the correct oil drain interval from Table 3.

Table 1, Oil Drain Intervals
Vehicle/Equipment Kilometers / Miles / Hours / Months

Truck crane/yard spotter 10,000 / 6,000 / 250 / 3
Paver/crane/backhoe N/A / N/A / 250 / 3
Dozer/scraper/skidder N/A / N/A / 250 / 3

Table 2, Oil Drain Intervals
Vehicle/Equipment Kilometers / Miles / Hours / Months

Tractor/combine/irrigation equipment N/A / N/A / 250 / 3
Genset/air compressor/fire pump N/A / N/A / 250 / 3

Table 3, Oil Drain Intervals
Vehicle/Equipment Kilometers / Miles / Hours / Months

All others 10,000 / 6,000 / 250 / 3

I recommend you set up a Quickserve account with Cummins and see what is recommended for your engine serial number. It also helps when identifying the correct parts required for maintenance or repairs.

Just my $.02.

Now see, there you go!

I wonder if the extended change intervals are due to synthetic fluids being used. I tend to stick by the 12 month rule as there is no way I can do 20K a year.

These two notes appear to be S.O.P. though.

*Oil, fuel and water filters should be changed at every oil change.

**If engine is equipped with an optional coolant filter, it will need to be replaced on the same intervals as the oil filter.

I would also add that if there is a coalescing filter, there might also be a separate dessicant filter/cartridge that needs to be changed at the same time. Of course it depends on the brand and model of the air dryer but mine has both as well as three different valves that need to be checked for proper function.

No.

Cummins does not recommend synthetic oil.

Cummins doesn't care if you use synthetic, as long as you do not exceed oil change intervals.

As route 66 stated it is one year or 20,000. There is a special note for RV that directs it be done at least once a year. They know that the typical RV owner will never reach the hours, miles, or time they state for truck usage.
