need oil help pls

[sanbar21jb]

ok guys what is the best oil to run in a 6.0? is ther any problem with that rotella t5 10w-30

[403Grizz]

5w40 Syn!! Rotella, Amsoil, Mobile 1, are just a few. 5w40 is what most of the guys will tell you too run, you want a quality brand full Syn. I am running a 10w40 Syn (Petro Canada) currently but will most likely switch.

Mobil is good. I use it. Keep the oil changes under 7,000 miles.

The dealer that I go to uses Mobil Delvac 5w-40 full synthetic, have not checked to see what is different then regular Mobil 1. Just make sure whatever you use it has a CJ-4 rating.

I'm also running Mobil Delvac 1 5w40 full syn. It is approved by Ford, and sold at the dealerships.

Really, any full syn 5w40 will make your truck happy.

Redline synthetic, Rotella T6,

Amazon.com: Red Line 15W40 Diesel Motor Oil - 1 Gallon, Pack of 4: Automotive

167 for 4 gallons delivered for redline
It is ester based, some of the best oil in the world.

Rotella T6 is a blend of group III (refined dyno oil) and PAO.

COMPOSITION/INFORMATION ON INGREDIENTS
Blend of polyolefins and additives.
Highly refined mineral oil.

If you want to run regular oil, Delo LE 15w40
An oil change will cost you 45 bucks and you can change it every 3000-4000 miles. Very good stuff. Cheap at Walmart.

ok guys thanks for all the help i will probably stay with rotella? would a 10w-30 make the truck run a little warmer?

[Chango]

Rotella does seem to be a favorite around here ( I run T6) but like said above 5-40 syn will do ya right. Check out the thread on oil in my sig

Good morning Mitch,

That is good to hear, I did not know you were a fan of redline.
It is great, just not readily available if you don't order it ahead of time.
I think our friend sanbar did not realize how expensive the "best" can get lol.
What he really meant was "the best cheap oil". Love to see the sticker shock reaction.

sanbar, if you aren't towing T5 will be fine. T6 if you run the truck hard or tow.
If you change your mind, there is even cheaper!


T5 will run you about 80 bucks for 4 gallons.
Delo 15w40 will run about 48 or less.
