I recently posted where I compared 2017 fuel, bronze bushings, and shale as all feeling like they were slowly oozing oil. What have you handled that felt this way?
2017 fuel
bronze bushings
shale
teflon or similar lubricating plastics
skin or other living stuff (yourself or another creature)
The 2017 fuel is made from polyethylene (PE), which in general (and even more so for LDPE) is a pretty soft and gummy thermoplastic. These properties make it both well suited for the functionality of whiffle balls, as well as largely eliminating the possibility of it causing skidmarks on gym floors or walls if used indoors.
My 1974 Chevy Vega. Add a quart of oil with every gas fill up.
Man I miss that car.
It rusted so bad that when you drove through a puddle, your feet got wet…
