new truck

[757kevin]

i just got a new 99 f250 7.3 with 216k miles. this is my first diesel that i have owned and i am wondering about a few things. what kind of oil is best for these as well as oil filter? ive been running rotella 15-40 in the 89 7.3 that i work out of. is this acceptable? do i have fuel water filters? if so where are they and how often do i need to drain them? are the diff covers with the fins really worth it? i dont tow anything really heavy just a 16 jon boat during duck season. i got the truck fairly cheap due to it needing a hpop. so im not afraid to dump some money into this truck to get it running solid and dependable.

standard 15-40 dino il is fine.
a lot of people like the rotella t6 synthetic. thats what im gonna try
the next time i change my oil.
if its cold where you live you can use 5-40 synthetic.
i use wix filters (napa gold), a lot of guys use motorcraft ones.
the fuel filter is under the powerstroke cover if its not broke off. right on top of the motor.
i change it between 7,500-10k miles.
no need to drain it unless you get the water in fuel light.
and as far as the diff cover goes, thats your preference.
i would do the usual maintennce on everything, trans, transfer case, differentials and so on.

the rear end takes 75w-140 synthetic only. with limited slip added unless the gear oil already has it added.
i went with valvoline full synthetic with the limited slip additive already in it.
it takes 4-5 quarts i cant remember.

Yup, I love the rotella 5-40, well worth it in the way the truck starts when cold. I prefer motorcraft filters, oil and fuel, I just wouldn't use 'fram' or that stuff. I change at 10k fuel, 5k oil.
As for diff covers, I don't think they are worth the bread unless you are mega towing guy otherwise a good fluid will keep everything happy.
x2 on changing all the fluids in the whole truck, then you know where you stand.
I'd also check out your glow plug system (see sticky above) to see if you have any issues there to address in an older truck.

Enjoy - we all love these things!

yeah i was planning on stopping at napa when i get off of work in the morning. i guess i just need to find all the fluid capacities for everything. then spend a few hours in the drive way getting everything up to date. any good sites that can give me the specs for my truck?
