Penetrating Fluids Effectivity

The April/May edition of Machinist's Workshop did a test of penetrating oils where they measured the force required to loosen rusty test devices. Buy the issue if you want to see how they did the test. The results reported were interesting. The lower the number of pounds the better. Mighty interesting results for simple acetone and tranny fluid!

Penetrating oil .. Average load .. Price per fluid ounce
None ................. 516 pounds ..
WD-40 .............. 238 pounds .. $0.25
PB Blaster ......... 214 pounds .. $0.35
Liquid Wrench ... 127 pounds .. $0.21
Kano Kroil ......... 106 pounds .. $0.75
ATF-Acetone mix.. 53 pounds .. $0.10

The ATF-Acetone mix was a 50/50 mix (1 to 1 ratio).

Steve and I have run some ATF through many fine beater cars... We would go to salvage auctions and pick up a car for $50 or $60. The cars that are "driving while suspended/uninsured" are the ones I'm talking about here. There are usually horrendously maintained vehicles... Sludge for oil. Put a quart of ATF through it, let it run for about 30 minutes driving around. Change the oil. I swear you'd think it was a different car. Cleans alot of crud out of the engine. This is not something I would do with a "Good" car, but with a $50 car - you betcha.

And for the record, some of those cars I drove for YEARS after doing that and sold them running better than ever.
