Marvel mystery oil, Lucas, Two stroke, ATF?

[Mopardragster]

I have had my D350 for about a week now and my buddies are pushing me to run a fuel additive. One is singing the praises of Lucas and one is pushing Marvel Mystery Oil. Yet another is pushing two stroke or simple ATF. What are your experiences with this stuff. And what would you guys reccomend?

[CumminsPower59]

A lot of guys are running different things, just don't run ATF. There are a lot of additiives and stuff in there that can be harmful to the VE. Personally, I have had good luck with Power Service, although I only use additive in the winter months to prevent gelling.

[JustinRhodes]

Back when I had a ve on my truck, when i changed the filters I put about half atf in it. Ive always done that and still do with the ppump.

Whats so harmful about it?

[CumminsPower59]

Something about friction modifiers and the like, I'm no expert on ATF, but since its not designed to be burnt unlike typical additives, I ain't gonna run it. Some folks may have good luck with it, but in this case, to each their own

[bmoeller]

Yep, Ike is right. NO ATF!

If you run oil, ashless 2 cycle is the best. Outside of that, Lucas, Power Service,...........

[dazedandconfused]

Power service since 2 stroke oil has went insanely high.

There's only 1 atf with friction modifiers that ADD friction and not releave it and that's type F. Ford intro'd that. Read

Trans fluid now days have nothing in it to add friction anywhere in a trans. Back in the day when a c6 or c4 was "the" trans in ford apps you had cast valve bodies and steel valves. Now you have aluminum vb's with magnesium valve that are easy to scare and can stick with the slightest grit or grime.

This debate has been hashed before and there was one point I made that I didn't receive and answer to, if there's so much bad stuff in it that will damage you pump and injectors how come a brass bushing can maintain a close tolerance riding a steel shaft spining thousands of rpms. How can steel pump gears spin the rpms of your motor and not gald their cast iron housings.

Say what you will about it,my truck has been fed it for 223k. Until a month ago that was with the stock injectors and a 5yr old pump with 112ish k on it. Pump's still pumpin and I seen no build up of any kind in it when I install the 366 spring.

I use new clean dex/mercIII

[JustinRhodes]

Levi was it you that put atf in my new fuel filter when I limped my truck to your house when my fuel lines was sucking air?

If it was, that's when I first started with atf. Ever since then every filter, and about once a month my truck got some atf ran through it.

I did run seafoam and power service stuff once because I got it free each and couldn't really tell a difference.

[cmann250]

I run Power Service and I got my best MPG using it, so I have ever since. Mainly for good luck My only issue with ATF is it's red and Barney Fife may object if I'm ever unlucky enough to get my tank dipped

[Tacoclaw]

Yeah, I've always just dumped some ATF in the filter when I do a change. It saves me from having walk to the diesel pump to fill it or sitting there priming.

I agree with Ellis, if ATF had something in it that was bad for moving steel parts, there's no freaking way an automatic trans would be able to function. They're nothing but steel and aluminum moving parts.

The answer is as simple as COOLANT, which ATF is ALSO good at doing, since it also has a high heat transfer rate.
Also, brass is usually porous, which also tends to hold oil-based products to shafts with less tendency towards spin off under high loads and heat.
A transmission not only has many brass bushings, but extremely high volumes of fluid capacity, specifically for combating constantly bleeding hydraulic pressure, AND to cool loaded surfaces.
A transmission ALSO has numerous parts that are much HARDER than many engine (and injection pump) components, which also serves to combat lubrication/coolant failures.

As I have mentioned before, if you feel really safe running ATF as a motor fuel, try running ATF in a 2 stroke for a long period and see how far it gets you.

The bushings in a 727 based trans are slick and usually have a steel backing. Most have lube grooves cut into them as well. Your right in the lube area. A trans does throw massive amounts of oil to its parts but only at certain times,mainly in manual low and reverse,in finale drive,not so much.
You and I both know what is in these trans and few parts are "hardened". Maybe the sprag race or low reverse drum or pump gears idk.

The main reason for my use of it is the detergents in it. If it adds lubricating properties great,in my mind it should. At very lest it should equal the 2cycle oil.

Who decided that 2stroke oil was "THE" thing to use anyhow. Anyone ever think to take down a weedeater to look at the build up of carbon
If it does its job as a certain mix are you mixing it properly? Or are you just making yourself "feel" better by running it

Bottom line, if you want to be sure,run what's intended to be used in diesel fuel. If you want to be a cheap basturd,like me , run the other stuff.

I run Power Service in winter and straight diesel in summer. No one can provide proof that you need to add at any other time. The PS is mainly for gelling.

MMO's MSDS sheet lists it as a Petroleum Distillate, main ingredient being mineral spirits.
PS + Cetane Boost MSDS sheet~ Main Ingredients: Petroleum Distillates, Alkyl Nitrates, Aromatic Hydrocarbons, Glycol Ether

There you have it folks. MMO is nearly as good as PS+

[CUMMINSDODGEMAN3]

or if you have a diesel shop around you id see if they have any stanadyne they could sell or buy it. thats some really great stuff and what better company to buy a fuel treatment then to buy it from someone who makes injection pumps...

[oldestof11]

MSDS sheet shows Stanadyne some similarities to Power Service...
