Which Penetrating Oil is Best?

This test demonstrates that not all penetrating oils are equal.

Also, paying more doesn’t result in better performance. In this showdown, Project Farm puts to the test:

• ATF/Acetone mix
• AeroKroil
• Liquid Wrench
• PB Blaster
• Royal Purple
• WD-40

Results: Liquid Wrench came out on top, following by ATF/Acetone, Royal Purple, WD-40, PB Blaster, and AeroKroil.
