Thanks.

What were you doing with the truck to categorize the use as "severe" ?

Have you used anything else besides ST 15w-40 in this truck? Would be nice to see if another brand of oil had the same thing with thin viscosity like they mentioned in this UOA.

Mostly heavy towing all summer...12k # or more, lots of idling through cattle pastures, extreme summer temps, one long trip to pick up a trailer that was 15 hours away. Man, when I lay it all out, I am pretty impressed with this oil LOL. My oil temps never got above 225, so the truck does a great job of cooling even under pressure.

The PO used conventional Rotella religiously, but I have used ST since I have owned it. I bought it two years ago and have put about 50k on it since then.

Is it severe use? Sounds more like it was used the way it was intended.

5k is pretty doable on just about any oil.

What does the owners manual say?

This was ST conventional correct?

I have used this oil in my diesel truck for at least 2 years, there is nothing wrong with this oil.

I bought whatever is the cheapest. This time, the Mobil Delvac 1300S is cheaper after rebate.
So that is what I will use next.

Is this UOA is for ST conventional or synthetic?

Ahh yea sounds like what any manufacturer would considered severe use...

1) Mostly heavy towing all summer...12k # or more
2) Lots of idling through cattle pastures
3) Extreme summer temps, one long trip to pick up a trailer that was 15 hours away

To be honest I am impressed with your UOA for a cheap conventional oil. I would definitely agree with you that you put it through severe use.

What oil filter do you use?

Motorcraft from Walmart...10 bucks. They are well made and tough.

Definitely what Ford would consider severe service conditions. Definitely performed well.

Yeah, I would say that's pretty severe considering dust conditions, dry grass, high outside temps, and the heavy towing for 75% of the miles used. "Normal" might be city driving, very little towing, and no dusty conditions. This was far from that, owners manual or not.

I can be wrong but I think Supertech HD 15W-40 is a dino NOT synthetic for Diesel engine.
Synthetic commonly made to be 5w-40.

Yup, it's conventional, which I think I said a few posts back. I don't use syn in anything anymore. I got off that bandwagon about 10 years ago.

Thanks! I thought so...and my engine looks great too. This is the first UOA I did on this truck. I just did it to get an overall picture of health. I don't normally do them because I change every 5k no matter what.

Re: UOA--Supertech Severe Use on a 7.3 PSD - 10/11/18 04:16 AM

Seeing this, I can be more confident running Supertech 15W40 in my early 99 7.3, I used it for the last oil change but drained it out with only 100 miles on it for motorcraft 15W40, it made me nervous. Ill try it again as Im due for an oil change

Supertech made you nervous?! It wouldn't be on the shelf if it didn't work. I guess big name brands have people worried over hype. Use it, save $$, and rest easy.

Impressive! My V6 3.0L reaches 260° towing less than 9k.

Fair enough. It just appears to me that the truck was being used as it was intended so I was genuinely curious.

I've had great UOAs from ST fluids in many applications (PCMS and HDEO).
This does not surprise me at all.
ST dino lubes are great stuff, as are most all house brands from large names we all recognize (AAP, Napa, OR, AZ, and many, many others.)
If it's API licensed, it's good enough for normal (and even severe) service.

I ran some experiments several years back where I ran 15k miles on ST dino PCMO and a MC filter in my wife's Villager (VG30E Nissan drivetrain). Total soccer-mom use; short trips, multiple daily start/shutdown, summer/winter, etc. That 15k miles is FIVE TIMES longer than the "severe" 3k mile recommendation in the manual. And yet the UOA came back totally OK and within normal expected wear rates.

If an engine is in good operating condition, and the lube is appropriately selected, there's not much really severe about "severe" in a manual; it's overblown hyperbole that protects the warranty risks of the OEM while wasting the money of the consumer. I find it more than a bit ironic that we are constantly barraged by advertising on how tough and manly trucks are on the TV; pulling massive boats, hauling tons of hay, pulling excavators up long steep inclines, and yet when you open the owner's manual, you'd swear you just purchased a fragile tin can that needs constant lube/fluid attention, as if using the truck like a truck is somehow "severe". I see no credible evidence that what qualifies as "severe" in most manuals ever manifests into a reality of substantial wear escalation. Abusive practices and neglect excluded, there's not much that a modern truck made in the last two decades cannot handle within it's stated limits. If a lube gets frag'd it's often because of a condition allowed to go out of bounds (poor cooling system performance; poor air filtration; excess fuel dilution; etc).

This UOA looks fine and nothing is of concern, despite a "cheap" lube being used.
Motor on!

Super Tech 15w40 is not made in a synthetic... very few 15w40’s are syn. Redline is the only one that comes to mind. Rotella T5 15w40 is a syn blend, but that’s the closest to syn I am aware of when it comes to the “common” oils.

Re: UOA--Supertech Severe Use on a 7.3 PSD - 10/12/18 01:02 AM

RP makes one, too, I believe. Actually, they probably make two, since they have actual commercial HDEOs and the 15w-40 HDEO they always did in their "API" line.

Re: UOA--Supertech Severe Use on a 7.3 PSD - 10/12/18 10:22 AM

Super Tech oil is NOT a cheap oil, meaning the cost of the oil is the same, no matter what brand name is on it.

Its the same or better quality then any "branded oil" without the price mark-up that branding requires for extra profit.

Its a low markup oil that is just as good or better then any other, with the same exact API rating.

Re: UOA--Supertech Severe Use on a 7.3 PSD - 10/12/18 04:45 PM

The thing that amazes me is there are GREAT UOA’s on just about every SuperTech oil on the shelf (dino and syn), and yet somehow those numbers (“proof is in the puddding”) still don’t convince folks it is as good as similar name brand oil!

Just picked up a jug of 5w30 High Mileage SuperTech syn for the Nissan Juke in our household. Just under $16 for the syn vs just under $13 for SuperTech 5w30 Dino... add a good filter and it’s a no brainer. At the price AND with real results, SuperTech (especially syn) makes sense!

Yes, very true. It is a bit or few $$ above Harvest King oil but I'll take ST oil any day smile

Super Tech 15W40 continues to produce good UOA results in the 7.3L Powerstroke. Walmart will be upgrading the oil to CK4; however, the timetable is unknown. In my area, Walmart has Super Tech 15W40 priced at $9.64/gal - a good value. I plan on using Super Tech 15W40 for my upcoming OCI.

Re: UOA--Supertech Severe Use on a 7.3 PSD - 03/28/19 05:32 PM

15W-40 oils are better than the syn 5W-40 except for below freezing starts.

Re: UOA--Supertech Severe Use on a 7.3 PSD - 03/31/19 03:28 PM

I have questions about the obvious and well known shearing with this engine. Does it occur if s straight 30 or 40 is used? What happens if a multiviscosity oil is used for a reasonable longer OCI like 10k mi? What about 20-30k?
Is shearing why the recommended OCI is so short?

Re: UOA--Supertech Severe Use on a 7.3 PSD - 03/31/19 03:49 PM

I had a 2002 "actually the wife " F250 Powerstroke that she and the daughters towed their horses to events etc and used the truck for getting hay and dump runs .I did several UOAS through out our ownership and the uoas came back fine and the oil 15w-40 came back with in grade. The 7.3 is a decent engine.

You'll get flack for making such a blanket statement, but I agree and have seen better UOA on many 15w vs their 5w offerings.

Re: UOA--Supertech Severe Use on a 7.3 PSD - 04/02/19 10:26 PM

Blame mostly RT6 for that. It's not a bad oil. Doesn't turn out bad UOAs. They are kind of lackluster many times, though.
