A Machinist's Workshop magazine recently published this info on penitrating oils

OIL AVE TORQUE TO LOOSEN
NO OIL USED 516#
WD-40 238#
PB BLASTER 214#
LIQUID WRENCH 127#
KANO KROLL 106#
ATF*-ACETONE MIX 53#

The ATF-ACETONE mix is a home brew mix of 50-50-automatic transmission fluid and acetone. Laquer thinner can be substituted acetone.

I don't know how scientific the tests were but I thought quite interesting. Has anyone used the ATF mix?

WD-40 isn't a penetration oil, it's a lubricant.

I've used both PB Blaster and Liquid Wrench, both work just as effectively.

The ATF/acetone mix is what guys use to unstick rusted cylinders. May take a couple weeks or even longer, plus heat cycling, but it usually produces favorable results. As for the mix on stuck bolts, never really had to try it. Usually an off-the-shelf penetrating fluid and sometimes some heat, plus an impact driver/hammer (ALWAYS) will do the trick.

I've undone just about every rusty and stuck bolt on my 40-year old motorcycle and have only had to slot or dremel 3.

Acutally, WD40 isn't a lubricant, it's water displacement (Hince the WD). I've used Kroil Oil, and it's very good, better than PB Blaster of Liquid Wrench, but I also use both of those for different projects.

Call it whatever you want, but WD-40 is a great product that can be found in most locksmith's tool tray. Countless service calls for jammed, stuck or frozen locks and panic exit devices over my 40 year career were quickly solved with a squirt of WD-40 in the right spot. It helps free up, clean and lubricate any mechanism. I believe it is kerosene based. I have found nothing to replace it.

I use liquid wrench but I soak the bolts twice a day till I'm ready and I haven't had a problem with any bolt yet with a breaker bar. Most bolts I have needed off are original and never taken off before. Did a motor and trans swap Maybe I'm just lucky. Suspension is next.:dontknow::dontknow:

I work in a power plant and kroil is amazing the rule is let it soak right now i am frame off restoring a 1972 michigan car and havent had any probs geting nuts and bolts free just shoot them with kroil and take them out the next day an other trick is to warm the bolt with a propane torch and dab bees wax on it it sucks in like solder and frees it up

Anyone one else order any Kroil from the above link, Kanolabs/google offer? I ordered almost three weeks ago and have yet to receive my order. My credit card was charged but I have not seen any invoice or shipping/tracking for order.

Thanks
