transmission Fuid in Fuel Tank?????????

[CumminsPuller]

Awhile back I thought I had read a post on here about some guys asking about putting a quart or so of transmission fluid/motor oil in with your fuel... ..... Or pre-filling your fuel filter housing after changing the filter with either on of the two fluids... ... . I know it is all incorrect practices, just wanted to read all the theories and supporting facts. If anyone can point me to the thread about this discussion I would appreciate it. I looked but could not find any information. Thanks

Adding ATF to diesel is something that is left over from the days when ATF didn't have all the additives it does now and fuel treatments designed for diesel weren't as widely available. The short of it is modern ATF is designed not to burn and will leave damaging ash deposits in your engine. Use an additive designed for diesel fuel.

What about Marvel Mystery Oil?

Motorhead,

Do a search on Marvel Mystery Oil, a. k. a. MMO, there was long thread on it a month or so ago on it.

Marvel Mystery Oil

Motorhead,



Marvel Mystery Oil has been around for a long time. It has

also been added to Diesel fuel since its introduction.

I have seen it used as a fuel treatment since I was a

Cummins engine apprentice in the 1950's.

I myself am an addict of this stuff, as I have seen it as an improvement when added to correct measure in a Diesel engine

fuel system.

"snake oil" it is called by some detractors, but on the whole it has proved some results that has enabled the stuff to remain on the market for years now.

When My first generation Dodge starts to idle a little rough, I put in 12 oz. with a fuel up. It just seems to smooth it out after 100 miles or so. It seems to work for Me.

Don't know why it does it but a few members here have directly linked fuel level sender failures to MMO. When use is discontinued the senders have recovered.



Looking at MMO's material data sheet shows it to be more of a solvent than a lubricant. My feeling is that while it probably won't damage your engine anything more than occasional use for carbon removal purposes is a waste of money.



Once again stick with an additive designed for diesel fuel.
