What are you guys using to replace the "Sulpher" to lubricate your engines?! Will "MMO" Marvel Mystery Oil be bad for it ?

 

The "sulpher" did not lubricate our engines. Alot of people use MMO, Power Service, Howes, Lucas, many more. MMO will ge great.

Thanks Jim

Saw "Stanadyne" on this board, where's the cheapest place on the internet to buy it, counting shipping?!

 

Someone told my neighbor with a Duramax that they sell sulfur to add. Anyone ever heard of that?

 

i use a little bit of 2-cycle oil in my tank. maybe 3 or 4 ounces to a full tank. It does keep the IP a little more quiet. Got the idea from a truck driver freind of mine.

 

Good Grief!
I wonder who is putting this idea out??... Because just this very day, a fellow co-worker (with a DuraMax) asked me if I knew where one could get some sulphur containing diesel fuel additive to add sulphur back to the fuel for his DuraMax!!!...

He had heard it from someone, somewhere that it would help.
I guess someone has greatly confused lubricity additives with real sulphur!

As I told him:
Adding sulphur is the last thing that you want to do.

In a nutshell, the problem with LSD/ULSD fuel arises during the refining process where in the effort to strip all the sulphur out, some of the "good" lubricating oil fractions that sulphur likes to reside in are unfortunately removed.
Since the good lubricating stuff has already been taken out, putting sulphur back in won't do ANY good. (actually bad from the extra sooting/polluting the SO2 causes)
As I told him, just enjoy the ULSD for the lower sooting quality it has.
If he wants to do anything, put some Stanadyne, Power Service etc. in it for a little extra lubricity in consideration of his pump.

I *think* it may have been someone at the dealership, but don't quote me on that. Seems some folks at Chevy could be poorly misguided

 

I've been using powerservice and biodiesel for pump lubricity issues. My local station does have the ULSD now, so I always add powerservice when I fill up with dino diesel. Every third or fourth fill up I try to make it to the city for B99.

 

I add the 2 stroke oil myself and use Power Service during the winter months. My local pump rebuilder who is also a Bosch authorized rebuilder has been resealing tons of injection pumps that have suddenly started leaking. He blames it on the ULSD and even has the message that Cummins sent out on the leaking issues due to ULSD posted. He is also suggesting that everyone use an additive. They sell Howes and Stanadyne at the store but also like the 2 stroke oil. I used to use the MMO but was told that it is a solvent and not a true lubricant. I question that as I have an old Farmall engine with MMO setting in the bores to keep it from rusting and it is not evaporating like a solvent.

 

I use MMO as light machine oil on all kinds of things in the shop, and it doesn't act like solvent.

 

been using a Lucas product for the last 4 or 5 tanks. . .runs a little quieter.

 

I add biodiesel for lubrication.
