Fuel lubricants, what are you using?....

[Tin Roadtube Vagrant]

Going from low-sulfur, to ultra-low sulfur has me concerned about the old CAT choking on dry bread. I have a friend who vends diesel. He claims modern additives are sufficient. I'm a doubter and skeptic. The same guy tells me additives are the crux of profitability in fuel sales and the less you inject the more money the vendor makes.

Was introduced to Opti-lube line. I read the independent study and was impressed. Always looking for something better, however. Curious what people are using and why? Crazy to see some common lubricants actually dropped fuel below baseline lubricity, I was NOT expecting that. Even more amazed at how well straight biodiesel did.

I run Wal-Mart Marine 2 stroke(tcw3) oil in my diesel tank. 1oz per gallon or 128:1. It will lubricate the injection pump and "potentially" reduce the washing of the cylinders at long idles. I don't know if i would do it with a common rail as it can foul those injectors. I would check to see some research on your 3126 directly. Not sure whats best for a HEUI engine.

7) Super Tech Outboard 2-Cycle TC-W3 Engine Oil
Unconventional
(Not ULSD compliant, may damage 2007 or newer systems)
HFRR 474, 162 micron improvement
200:1 ratio
16.64 oz/tank
$1.09/tank

Is this the actual brand you use Tippin? Placed 7th best of the 19. Lol, Luv it, did better than some big label diesel fuel additives! I think that's a Walmart label (Super Tech)?

That's the one. I'm a few years out from my research on it. But surprisingly the generic SuperTech was a real bang for the buck and beat the brand names at some tests. For me it was easy, the dodge forums discussed this over hundreds of threads and had a real consensus for my engine.


It helps i use the same stuff in my boat, so i have got a real supply.

I'm not too concerned about older engines and ulsd. It's been around since 2006, and I've seen vastly more fuel system issues due to lack of maintenance then what I could even begin to attribute to lack of lube in ulsd. Bosch cp4 injection pumps are excluded from that, but those are also far from being considered "old".

Many companies make additives for fuel. Power service is endorsed by cummins and is the primary fuel additive manufacturer we sell. Stanadyne also has a lubricity additive that seems to work well. Guys use atf, motor oil, 2 cycle oil, etc. I don't think it's that big of a deal.

If you want to do your 3126 a favor, change the oil and filters more frequently then what the OE recommends. Also consider installing a centrifugal bypass style filter to remove soot throughout the OCI, and being a HEUI engine, use stiction eliminator from hotshots.

Sound advice, and CAT dealership buddy from school also told me to use OEM filters. I've been changing with Mobil Delvac 1300 super once a year and most years that's only about 2K miles. Sample tests are staying well under the 3% soot. It has blowby....not as in use the road draft tube as a makeshift Skoolie hairdryer, but I certainly have the expected 213,000 mile blowby.... soot should rise as she ages.

In our Dodge Cummins mechanical we use for delivery, we add a quart of cooking oil at each fill-up.
With its bigger tank, our ExpeditionVehicle gets a couple gallons of cooking oil at each fill-up.
.
Of course, a mechanical Cummins can operate just fine on straight cooking oil.
Or filtered used engine oil.
Or brake fluid.
Or waste restaurant oils.
And probably the fumes in any downtown of any major city.

i got the 97 kodiak with the 3116. i really like that one and run howes to keep my lubricity in this fuel. i was a mech in a truck shop when the fuel first changed. it was a nightmare as all the older trucks were dying. had LOTS of incompatabilty with every rubber or synthitic surface. clogged fuel systems were so common and nothing we had available would ork to prevent it. they finally got some new hoses made of a new material that worked. meantime a lot of owner operators called it quits or went bankrupt. kind of the same thing we went thru in the 70s when they removed lead before the engine manufactors could develop a valve train that would stand up to the lead free fuel. new cars with 30k miles needing a valve job. my new harley got one at 7k.

Wow, Leaded fuel issues, sir you just aged yourself!!

We had ULSDiesel issues with the electronic racks in Bosch pumps. They began to stick in the zero-fuel position and kill instead of returning to idle. Adding fuel lubricant fixed it. Beyond that, only other engine with obvious issues were the old 6V-8V Detroit. Had injectors spalling and locking the rack at 500 hours, untimely, suspicious, deaths.

Yea ..... here's some more for you. I was good with 3 brush generators and spent lots of time adjusting the points in the mechanical regulators so we did not boil batteries. Replaced many series/parallel switches . Never got used to those damn air starters. And pulling the trapdoor on a oil pan to change the oil filter as Cummings thought the filter should be on the pickup side of the oil pump. As I look at the issues with the newer stuff I don't think it got any easier but since my talents are obsolete I wonder what's in store for you

HAHAHA, , that's why they call it the "Good'ol days" and not the "Gravy years". First time an ancient forklift came in with an adjustable regulator I had a 15-minute stare session and went to the book.

Had an older Cummins factory instructor (Lonnie) point out at the beginning of a course, "You young men are currently living in the good old days of engines". He didn't realize how right he was, that was 1995 and electronic diesels were doing amazing feats of clean HP and Torque. Zoom ahead to the start of 2003 tier 3 emissions and those years 1990-2003 really WERE the golden years of reliable diesel power.
