This is one of those recurring threads - I'm not necessarily disputing the study but one time I tried to find the source magazine, and I failed to find "Machinist Workshop" magazine, "Machinist" or anything similar with a report like this.

You would think that with all the car-related boards on the net someone would have chased this down and reached the source, but I couldn't find it.

Another +1 for PB Blaster...I have found it to work much better at getting things loose than any of the other penetrants, though I haven't used ATF+acetone. It smells nice too.

I did some research on the ATF + Acetone mix. This particular "study" is posted on a bunch of other car related message boards. But everyone is like oooh, that's a good idea! Didn't seem like anyone actually tried it...

This is my first post to this forum. I thought it would be about my recently acquired 1989 420SEL, but apparently, not yet. The car is great and while I have a few issues with it, I thought I'd chime in on this one.

I own a motorcycle salvage business. While I no longer do the "dirty work", I certainly used to. I have a "Dismemberment Technician" to handle that for me. We handle everything from fresh corpses to bikes that have been sitting on the the Oregon Coast for 20 years. Over the years, we have tried every commercial product including PB Blaster, Liquid Wrench, Kroil, etc. WD40 is not even in the same catagory, as it was designed to be a water displacer (hence the "WD"). It does work well when sanding aluminum prior to polishing. We have also tried the acetone/ATF mixture, Coca Cola, molasses and water, fresh squeezed monkey spleen fluid and whatever else was put forth on the internet. By far, in my own personal experience, Kroil is the winner. We go through a couple cases a year and it's worth every penny. It's more money that PB Blaster, but lasts 3 times as long.
A hot torch is also a close second, but you can't always use it where an open flame might ignite the children.

Anyway, my 2 cents. You got what you paid for it.

Oh, by the way, I also own a 21 year old Mercedes...........
