Was thinking about running Rotella but didnt know if there is a certain oil that these trucks like. Mines a 95 7.3 2wd crew cab dually with auto trans. Should i got conventional, blend, or synthetic? I know its usually a matter of personal opinion but just curious what everyone else is running. Also how much oil does my truck hold?

 

I like rotella 15-40 conventional. It's the only thing I buy at wal-mart along with the Ford oil filter.

 

Schaeffers 7000, 14 quarts.

 

Delo 15-40 here.

 

Motorcraft 15-40 here. 14 qtz

 

Rotella T 15w 40. Motorcraft 1995 filter. Been good. 14 qts

 

I always use Schaeffer 7000. Really nice stuff but a bit hard to find and expensive.

 

$20 a gallon is inline with Rotella syn.

 

I use Rotella 15w-40 and because i'm getting up there 260,000 I add 2 bottles of STP oil treatment. Still rolling coal when ever I want.

 

Valvoline super blue 15w40 conventional.
What can I say...gotta b different lol

 

we've noticed

 

Ditto.

I punch a hole in the bottom of the filter to drain it. Pre-fill (takes a little time for it to sift through the filter) before installing. And write the date and miles on it with a sharpie.

 

Been using Schaeffers Supreme 7000 15W-40 (14-15 quarts, depending on how I feel that day) and the Motorcraft FL 1995 filter. Very pleased with the Schaeffers. Runs smoother, quieter, and seems to maintain viscosity better over the 5000 mile interval. I buy it on Amazon, and a complete oil change costs right at $100.

Was running Mystik Super HD but the oil sample results were consistently showing lower viscosity about half way through the change interval.

 

Rotella 15w40 338000 no problem

 

Thats nice to know you can buy Schaeffers on amazon. I have been getting it at the local Napa but they never have it in stock so I have to buy a gallon every time they have it until I have enough
