Years ago I had a neighbor who used to own a gas station before he retired. He had two or three barrels of motor oil and cases of 'Motor Medic' and STP in his garage that he had brought home when he sold the business. He had a big fireplace and a wood stove to heat the garage with, so he was always cutting wood. His saw was an old David Bradley model from Sears.
It was loud, heavy, and completely soaked top to bottom with dusty oil and grease. It threw oil everywhere when it ran, plus he'd pour his home made mix all over it when he was cutting something big. The spot where he cut his fire wood in the back yard looked like it was paved with asphalt from all the years of dumping oil over the saw in the same spot. It was a mix of oil soaked dirt and saw dust matted down over time to the point it could pass for pavement.
When he passed, the new owners just paved over that spot with new asphalt to cover it up I guess.
I seem to recall his mix being 3:1, motor oil to STP or any thick oil additive he had there. The result was an amber sticky mess that flew off the chain in long streaks.
(Keep in mind this is the same guy who used to collect used newspapers and drain oil from a local heavy truck shop to burn in his fireplace. He'd sit for hours and roll up 'logs' out of tightly wound newspaper, he then glued the end roll and wrapped it in wire, then he'd soak those 'newspaper logs' in buckets of dark black diesel drain oil and use them in his fireplace in the house.
He said they burned super hot and that three of those would heat the whole house all night long.
His house was a mess, there was a film of that oil on everything, it smoked when it burned and it got on everything, not to mention simply from it getting dripped all over just putting them on the fire out of the old metal bucket of waste oil sitting next to the fireplace. He would spend all summer preparing paper logs like that for the next winter, he had buckets of them soaking all over he place.
The garage was full of barrels of oil and various solvents he brought home, plus some military surplus oil and chemicals. He also would use the drain oil in a few smaller saws, and he'd pour the waste oil around the property to kill weeds. To him it was sort of an all purpose solution to everything
