5/40w T6 is in short supply to NO supply and likely continuing into MID/LATE 2022, 15/40w T6 supply is also sparse to find. You can mix multi grades of the same MFG, Just DON"T do it 50/50....its also a good idea NOT to mix brands at service, adding different brand when low after miles of use...
Yep, Its unrelated to the failure, None the less its likely the entire powertrain warranty is voided. New Parts are about $4000.00 Plus about $2000.00 in labor plus shop supplies $50.00.
Hopefully this will include the VM3.0 in the future. Although the Mounting is entirely different. The CP4 on Cummins has the GP the VM3.0 does NOT, that's the only difference...
How Long It Lasts
The Powertrain Limited Warranty lasts for up to 5 years
or 100,000 miles on the odometer, whichever occurs
first, calculated from the start date of the Basic Limited
Warranty, as set forth in Section 2.1(E).
Diesel Engine:
Cylinder block and all internal parts; cylinder head...
Its all the same..... test it yourself..... Why waste the $. The deposits = Urea. DI or DS, actually DS IMO is superior to DI, DI is less cost to MFG. and that's why its used instead of DS. Thier are many that have been running DS for 10+ Year on CC/CTs error free into 700K+ miles.
I challenge EPA and API after, When I tested the Conditional behavior of Ram VM 3.0 AECD were conditional, That's why 1.5 Years before the EPA filed against Fiat for CAA violation. Also the 90% DS 10% Urea resulted in 95% of Driving that ratio met CAA requirements of Near 0 NOx, My best...
2015 Best DEF is 3 Gallons Distilled water to 1 Gallon DEF, I ran this ratio 4 Years and 45K miles error free. This Ratio 2014-17 will eliminate Most DEF Pump/Injector Codes and premature failure. This is Me in My 2013 Ram Cummins, I did the same procedure in My 2015 ED. ALL Retail DEF is 33%...
Go with Cummins, less cost in maintenance, ease of replacement and parts availability.. I today received 3 notices of price increases....IMO greatly impacted by GOV involvement in private businesses operations.
