Reading through all the threads and this will be my first oil change. I'm pretty sure i'm going to go with Shell Rotella T6 5W40. Found it for 51.69 for a case with 3 gallons. Is all shell T6 now CK4 and this is approved by for now correct? Is this a way better option than T5 15W40 synthetic blend? Thanks in advance for any advice!

 

I used the Shell T-6 a lot on my 2011 and 2015 trucks. With the dust up over the CK4 approval, I switched over to
Valvoline 5W-40 Premium Blue Extreme Synthetic Diesel Engine Oil when my first oil change came around on my 2017 truck. It is usually $62 on amazon, But I found it on sale this week
at Autozone for $13 a gallon.

I do prefer the full Synthetic in colder weather.

 

Well not to start a issue but following my normal process on new trucks changed my oil 3 weeks ago at 1800 (try for 1500) miles with AMSOIL Signature Series Max-Duty Synthetic Diesel 5-40 and a EA series filter.

 

Thanks for the info that looks like a good option as well and not a bad price on sale. That is a CK4 no too correct? My weather is Arizona so 118s on average days now and winter times at lowest get to 30 usually.

 

 

 

 

Yeah i was looking at their ad and noticed that. Was going to drive by the store but thanks now i don"t have to. I was set on the Shell T6 but didn't know if there was some additive in the now CK4 that was causing wear issues that maybe a brand like Valvoline PBE didnt contain. I like the full synthetic, I think that seems to be a good option for those who change their own oil. When i talked to the ford dealership however they advised me Ford recommended the synthetic blend motorcraft over full synthetic. Not sure why? If that is the case i could do the Shell T5

 

While your at it, install a Fumoto drain valve at this time. And from now on, no more messing with a drain plug and wrench, much cleaner too.

Good to know. I bought 3 gallons of the 5w-40 off Amazon and just grabbed 1 gallon of the 15w to top off my 13th quart. Glad I didn't buy a bunch and try to stock up.

 

My F450 just rolled over 1700 miles and I am thinking about changing the oil.
I have Rotella oil left over from my 2015 and after reading about oil for these engines it seems it may not be suitable?
I just had a trip to the Black Hills towing about 10k. Are there additives in the factory fill that I should leave in for a while longer?

 

 

Rotella? I need to read my oil jugs and see if its a CK-4 oil.

 

 

I have 6 jugs of Rotella synthetic in CJ-4, I assume this is safe to use?
And what is going on in Canada with the price of oil filters at the dealer? $33 bucks? I told them to keep it.
I have a few oil filters from the 2015 6.7. I wonder if these with fit the 2017?
