2015.5 DMAX Maintenance

[cullumj1]

hey guys,

I'm sure this has been posted a thousand times before but im curious about the maintenance schedule.... how often are yall changing oil, fuel filter, trans fluid.... I have 44k on the truck now and have changed the fuel filter once. I tend to change the oil every 5k miles or so...any help would be appreciated. now sure when to change the trans fluid? or if there is a time limit between fuel filters or if I should just use the "truck meter"

Fuel filter.

DIC or about 22,000 miles or about 2 years, whichever happens first. (usually mileage)

 

Trans

fluid and external filter about every 45,000mi

 

Engine oil/filter

DIC, but sometimes earlier to make it more convenient avoid changes during long trips or busy seasons

Typically ends up 10 - 20% remaining. (but sometimes it's after it gives the warning at 0% )

 

(as well as the truck in sig, I run an LML)

I've only got 60 thousand miles on my truck and I changed my fuel filter around 50k. Also did my internal and external transmission filter at the same time even though the book says to only change the external filter and fluid. Oil changes are synthetic only and I change it when the DIC gets under 4%.

Not sure why they say the internal doesn't need to be done.. both internal and external on the allison should be done. I'm getting ready to take mine into be flushed and both filters changed.

I thought it did.... external every 50 internal every 100
