STP oil treatment (Stay Together Please) is still out there !!

Was that the towns mosquito fogger ??
I’d almost forgotten my trip back from Reno with the /6 dart. The engine was slap worn out and leaked oil from everywhere. I stopped at the dollar store and bought a case of crappy oil
And 6 cans of STP. In 3000 miles I burnt or leaked 27 quarts of oil and all the STP. The entire under side of the car was soaked.
