Zinc oil supplement

All this stated is why I suggested Amsoil products like hot rod oil to be specific. Its scientificly formulated for all additives to work in unison and is independently tested to prove its a superior product.

Yeah, it’s expensive,but when changed at recommended extended oil change levels, it becomes cost effective.

I was reluctant at their claims, so I had it tested by the company that tests oil for over the road truckers multiple times. Their oil change intervals turned out to be spot on.

By the way, their oil filters are made by wix to their specifications and are also a superior product.
