I run Delo 400 with a can of seafoam every other change. I cut my fuel with 2 stroke oil. I only run Wix/Fleetguard filters for air (bhaf), oil and fuel (water separator delete)
Not to sound like im plugging my company but just a heads up for yall running Delvac, throughout the midwest and south all through sept. Oreily Auto Parts will be running a special on 5 gallon containers of Delvac 1300 as a harvest time special.

Mystik JT-8
Motorcraft 15w40 or
Valvoline Premium Blue 15w40
Rotella 15w40
CANNOT go wrong with those three.
One thing to consider is Motorcraft 15w40 is CI-4 rated, and it contains more Zinc and anti-wear additives since 99% of diesel oils on the market now are CJ-4 rated.
Sounds funny to run a "Ford" oil in a Dodge truck, but oil is oil- difference is the Motorcraft has more of the good stuff!! That is my non-technical explanation so you all do-not get bored reading!!
One major benefit to the motorcraft other than the heavy treatment of anti-wear additives is the high starting TBN. It starts out with a TBN of 14.
TBN stands for Total Base Number, it controls soot.. fuel.. and other contaminants which cause the oil to become acidic. Simply put, Motorcraft 15w40 has a 30-40% increase in TBN over other diesel oils. It's a long story, but this oil was designed for the 6.0L Superduty before all of the emissions crap came out in 2007/2008 so they still make the oil as CI-4.
One of the little known secrets in the world of diesel motor oil.
And you heard it here.. if you take advantage of it that's up to y'all.![Thumbs Up](https://www.dieselbombers.com/images/smilies/tu.gif)
Just make sure you get the bottle that says CI-4 [Charlie India-4]
IF you can find the red bottle of Motorcraft 15w40 with a CI-4 rating consider yourself very luck, as all CJ-4 rated oils have the level of additives cut way down.
Another good one is Mystik JT-8 15w40, it's a synthetic blend available at most farm stores / autoparts stores.
Truth is if motorcraft weren't available and I could FIND the Mystik JT-8 I'd prefer to run that.
JT-8 is also not as well known and it is one of the best available.
It's a synthetic blend with a good additive package for the same price as regular delo/rotella/ect!!
Looks like my local Advance auto now stocks Mystik JT-8 in 2 Gallon jug for 29.99 and they also stock Mystik synthetic blend gear oil for $4 a bottle.
Guess my differentials are getting fresh gear oil too!!
