Oil Change Question
I'm sure this has been beat to death but I'm too lazy to search right now.
I'm coming up on my first oil change with the new truck. If I recall, my old 5.9L took exactly three gallons to bring it up to the full line. What do the 6.7L engines take?
Also, what oil is everyone running right now? Is it still 15W-40? I used to use something in a blue bottle, which I think was Delo. Still good?
Thanks for supporting my lazy habits by responding with meaningful answers.

It takes 12 USqt or 3 US gallons, I use Amsoil Full synthetic oil, depending on the temp range you plan to operate in it says you MUST use 5W40 oil or engine damage will occur, I don't remember the temp but it was not THAT low so I just run the 5W40 synthetic year round. OK I went and looked up the temp range it's 0 F or -18C below that you can't use the 15W40.
Everything is the same as your old truck as with the 5.9. Even the filter, filter wrench, pre-filling the filter with new oil, 5 gallon bucket fits the same under the oil pan. You'll never know the difference.
While it may never get close to those temps where you live don't you ever drive anywhere cold like a skiing holiday, visit relatives, ice fishing?

I used 15-40 rotella in my 04.5 all the time all year and never had a problem. We used it in our big trucks and heavy equipment too along with farm machinery. I used Blackstone for oil reporting and always had an excellent report. I don't have a clue what the dealer has been using in my new truck. I know its rotella but not sure if they use the 5w-40 or not. I got lazy with this truck and I let them do it. But, I trust them as they aren't a typical dealer.
As for memory, that's a funny thing because I remember, back in the late 70's, walking 10 miles, thru 2 feet of snow, with rags around my feet, to get to school...

I was born in the late 70's. it's possible I walked through 2 feet snow for 10 miles but I certainly don't remember it.
Back to the oil change, I'm actually looking forward to it on this truck. My '03 was a 2WD and it was pretty low in the front. I certainly couldn't have fit a 5 gallon bucket under the oil pan. I had to drive it up on ramps just to slide my big ole' self under there. The new one should be easier. To make it even easier I ordered an EZ Drain Valve and tube from Geno's. No more messy hot oil running down my arm when I loosen that plug.

I would go to Wal-Mart and buy the large oil pan catcher. This will hold over three gallons of oil and will slide under the truck without raising the truck. I cut out the center so the oil will fill the pan faster and not pool on top. I slide under the truck and open up the Fumoto Drain Valve and then go inside and have lunch after a 1/2 hour or so the engine oil is drained from the truck. Refill with 3 gallons of Shell 15W-40 Rotella T oil and a new Fleetgaurd Stratapore filter. I also will grease the front drive shaft at that time along with any grease zerks on the front steering components.

I guess I drive too much. I got mine around the same time and I'm almost at the 7500 mark. No oil change light, but I'm deleted so that probably makes a difference.
