WHAT OIL ARE YOU USING IN A 2015 6.7
THANKS
AARON

 

A lot of guys are using Shell Rotella T6 Synthetic
Shell Rotella® Products - Shell Rotella

 

WHAT GRADE OIL 10W30 R 15W40
THANKS

 

I run 5W40 (severe duty cycle), but the manual states 10W30 for normal usage.

 

Rotella T6 here...

 

THANKS FOR INFO

 

T6 for me too. Safely handles all temp ranges and it's reasonably priced. Goes on sale regularly at various auto parts stores. When it's discounted below $17 per gallon I order 4 cases.

As a general rule, when you type in ALL CAPS it's taken as you yelling at everybody, so, are you still mad?

 

NOT MAD JUST LAZY

 

You can find most of these oils and the filter in Wally World or your local auto parts store. You don't need to bother with the dealer.


I run 15-40WT in mine.

 

I tow about 95% of the time so change my oil every 5K so I use 15W40. I use the Rotella, Valvoline and Motorcraft and buy when they are on sale.

 

John Deere Plus 50 II 10w-30

 

mobil 1 5w40

if you work your truck, i'd use it. theres no down side.

 

I used to be a HUGE fan of Mobil 1 products. I ran it in everything gas powered for over 10 years. I never ran it in a diesel though. I stopped using it a few years ago all together. I heard a couple of guys saying it wasn't lasting long and after reading the reports they got back from Blackstone, I agreed it wasn't the best choice anymore. Rotella T6 is a better product for the 6.7 Scorpion from everything that I have personally read, seen or heard.

 

I use Rotella T6 Synthetic 5w40.

 

Eh, what the heck.. this isn't my regional bs thread...
