+1 We've been over this before, it does not clean, and dilutes the quality of the motor oil.

I thought ATF, particularly Dex/Merc IV, is loaded with dispersants?

It has dispersants but a dispersant is only useful to prevent deposition. Here you're trying to clean something.

Someone else who knows details will no doubt chime in but I don't think any ATF would be "loaded" with dispersants either. Why would it be? What would you have to disperse?

ATF's are nothing more than glorified Hydraulic fluids .

I poured Rislone into my Cobalt a while back, and it seemed very thin and hardly a SAE20 carrier oil. Has anyone else noticed this?

A dispersant is there in ATF but in very low treatment levels since there are no combustion carbon deposits to disperse.

BTW, todays ATF's average as follows as chemistry has changed since that previous post:

Phosphorous - 0.3% AW additive
Zinc - 0.015% secondary anti-oxidant as ZDDP
Nitrogen - 0.9% Mostly anti-oxidants and Friction Modification chemistry
Boron - 0.16% AW additive
Calcium - 0.1% Detergent, tbn base chemistry, and rust inhibitor
Magnesium - < 0.005% if any
Sulfur - < = 0.33% AW
Barium - Not Used anymore
Dye - 100 to 250 ppm any color these days but usually red analine dye
Dispersant - Ashless succinimide dispersant (succinic ester-amide dispersant, phosphorylated and borated) ~ 300 ppm which is 1/10 that found in engine oils)


So as you can see, both detergent and dispersant levels are very low.

The value of a scientific theory is its ability to prompt further study, not that it has any relation to the established facts of scientific reality.

Here is a very simple test you can do. Next time you are working on the car and your hands are a mess get some clean transmission fluid and try to clean them. Then take off all the dirt that is left using clean engine oil. You will discover that clean engine oil makes a decent hand cleaner.

Just an easy simple test to confirm for yourself that ATF is not a good cleaner.

The Rislone for the additives chemistry and esters.
The Rislone (again) because Marvel is chlorocarbons

Is the nitrogen the amines? Is that what give ATF that sharp stink?

I'm going to guess maybe the sulfur?

Maybe the same thing that makes manual transmission fluid and a lot of gear oils smell like straight cat urine.

Rislone is designed to be used over many oil change intervals, never used MMO so I don't know about it. Depending on sludge severity get el cheapo oil and sub 1 qt of oil with 1 qt of trans fluid, and drain after a few hundred miles and add your preferred oil.

That's a great idea considering that ATF has high detergency.

Oh wait, it doesn't. So why would I want to dilute the oil like that?
