Major LMM Maintenance Questions

[Richard77]

the spin on prolly doesnt need to be changed that much but i plow with it it should be changed after the plow season just to be on the safe side

the trans filter is dirt cheap so i change it every oil change, i use the rotela 5w 40 also. mine is a 08 with 18,000 miles and tows only twice a month to the drags 12,000lbs and to work so it's not over worked yet

i have never changed the internal tans filter. only the spin on, once in 90k.

just drive it man, you'll love that LMM.

my LMM is all factory and i still like it, but i really enjoy my new 6.4 now haha.

With the DIC computing the Oil Filer Life, how do you adjust for the use of Synthetic? In other words, What is the DIC calculating for, Synthetic or Fossil oil? Then, if it is calculating for Fossil, how many more miles do you allow for synthetic?

i use 5w40 rotella t syn and by the monitoer i need to change my oil every 2000 miles is this normal thought i shoule at least beableto go 3000. the monitor went 4000 before it went to 0 with the original oil now it says it needs to be changed around 2000 why?

I have about 12K miles on the truck. My first oil change, it went about 3500 miles up to Alaska and the monitor was still reading 45%. But, being used to what a gasser's oil looked like, I changed it. It was very black. Then, I came all the way back from Alaska (~ 5K miles) and changed it again. At the second oil change it still had 10% "Remaining Oil Life." But, I changed it anyway.

According to the Operator's Manual, the Monitor calculates the remaining oil life based on use and conditions, etc. But, 2K miles seems a bit premature to me. Especially, given my experience with mine. IMO, 4K-5K is about it for me. I am still not used to black oil. I know, black oil is not necessarily bad. But, I am still trying to get used to it.

I'd just like to know how one compensates with the Monitor for the use of synthetic versus fossil oils.
