Rusts are alive and they grow and multiply on all of the tools I ever bought from Harbor Freight. Every single one of them even on copper if it came from there. It's totally insane.
Yair... I was kinda like... Detergent/ ZDDP... All polar head... Enough corrosion inhibit, already? Copper or Aluminium, atom heads, should corrode themselves, in the first place? :)
Oddly enough, ZDDP is one of the reasons that copper corrosion inhibitors are required. The Zinc in ZDDP can exchange with the copper metal - depositing Zn in the coolers and forming CuDDP in the lubricant. Fortunately this isn't particularly harmful as CuDDP is itself a very potent antiwear chemical, but it does cause a spike in ICP copper values.
This is so well explained, hope your channel booms! Thank You
Much appreciated!
Can you maybe make a video discussing the different corrosion inhibitors?

@@LubricationExplained where is the copper metal comes from? which part of engine is made of copper?
@@chunhwasee1490 In most applications it will be the oil coolers. In some cases it can also be part of bearing materials.
