What oil do you run?

Growing up in Arkansas, I only seen folks using Rotella 15w40.

The records on this truck show the previous owner used Mobil One 5w40 or Lubromoly? 10w40.

Looks like 3000 mile intervals.

O'reilly has a good deal on Rotella T6 5W40 full synthetic right now. $21.66 with a $5 rebate = $16.22. You can run Synthetic 7000 to 10,000 miles, with normal service, with hard service, just change the filter at 5000 miles. To check it out, change filter at 5000 miles and send in a sample for analysis.
Use the Motorcraft FL 1995 filter. O'reilly for $9.99, cheaper than Wallymart.

He sure wasted a lot of money doing that with synthetic. But ya know it was well taken care of. 3K mile interval and up to 5K interval is recommended for Dino oil like Rotella !5W40.

Use 5W40 in winter and 10W40 in summer. If your engine don't have the oil rail crossover, you should put one in it. http://cncfabricationllc.com/index....rication-7-3l-sd-hpop-hpx-crossover-line.html
These engine like a lot of oil flow for the injectors.

CNCfabrication also has the HPOP hi pressure lines for cheap, $50 ea, and there better than the $100 ones elsewhere. Good to have a set if only for spare, they can blow at any time.

By the way, put your truck info in your signature.

That is a good deal on T6 Rotella. OldBull: do the Powerstrokes drink the standard Rotella more than than Delo like the IDIs?

By the way: I wish I would have known about that cross over hose, I'll have to make one up, maybe stainless covered teflon

Rotella 5w-40 in both trucks, oil and filter changed at 5k miles. We don't drive a lot so that's about 2 changes per year. No oil use between changes, the 97 has 192k and the 99 has 238k

Ran delo in the 88, the 93 has rotella in it( drinks alot) at this rate probably 1-2 qts in 5 k?! next changeout gunna try something else.

I did use Rotella for a long time, then went to Delo, then Delo changed there forumula to Delo400 for the 2010 models and up IIRC, didn't like that, used Coastal 50/50. This is my first time with Rotella T6 5W40, sure made my engine sound a lot quieter, only have 183K on the engine. Haven't driven it yet any distance since my wiring problems, but going to relocate my 33' 5er, hopefully today.

I bought the HPOP lines and crossover line from dieselorings, they where damn expensive, wish I'd have known about CNC before that. HPOP lines were a $100 each. The crosover was a solid steel line, was hard to fit, can't remember the price for that.

Cenex Maxtron Enviro-Edge SAE 10W-40 winter
Cenex Maxtron Enviro-Edge SAE 15W-40 summer for me

My truck uses about 1 quart between oil changes, used 2-3 quarts with Delo, and drinks the Oreilly house brand oil about as fast as diesel

Mine is a 6.0 not a 7.3 so it's a bit more finicky about its oil. I used to run only the Motorcraft 15w40 Dino stuff, but 2 years ago switched to Chevron Delo 5w40 Full Synthetic. It gets changed at 5000 miles. both oils. The 6.0 is ******* oil, which is why I don't extend it......

Best thing to do is run a good quality, diesel rated oil, and you will be good to go. If you live where it gets cold, I recommend Full Synthetic.

I've ran the valvoline premium blue. (Not the synthetic one)
And travellers from tractor supply. I liked this one for the price. Looking it up, it's made by one of the bigger names.
Next oci I plan on switching to something else. Maybe synthetic.
There's some the guys with newer trucks have been running with great results. Made by lubrication Engineers. It's the monolec ultra 8800. Here's a bit of info on it. http://powerstrokearmy.com/forums/showthread.php?t=61338
I always run the Mobil 1 filter.

The PO ran Rotella 15w40 but after read about the 7.3L drinking that from many sources online I put Delo 400 in. I didn't loose any oil that I could tell until I passed about 6k, which was much too far.
I live in North Central Arkansas and Walmart carries Delo 400 for about $13/ gallon. I just can't afford the synthetic. I run the FL1995 as well, I think Walmart had that for about $9.

If you do make up your own line, be sure it's rated for at least 5000 PSI working.

I wonder what oil the railroads use in there diesel engines? It's gotta be ******* the engines with all the Idleing they do and Hi rev up when switching cars. The long distance engines are run near WOT for hours. I've never seen any reviews from any oil company.

I work at the railroad....
Nobody knows exactly what the oil is...
They say it's a premium "Diesel oil"
I do believe it is a sae 40.

The old 2 stroke EMD's do not require oil changes, just routine filter changes.
They burn so much oil there is no point to change it.

The 4 stroke GE's get oil changes with the same oil.
