Natural Engine Oil
You can now choose a natural, plant-based squeaky wheel oil instead of the
standard petroleum-based product. Jojoba “oil” is actually a liquid wax that
never goes rancid. Made from the jojoba tree, the liquid is not only a good
lubricant, but a great antiseptic as well.
You can use jojoba on squeaky hinges and wheels, and all other places you
would usually use a petroleum lubricant. (Note that although it would
probably work beautifully, we haven’t tested jojoba on a car engine!)
