Some years ago, I bought a 89 Hyundai for $75
It needed some work, a young kid from work had it and couldn’t get a salvage yard to come pocknit up for free. He said they wanted 75 to haul it off.
So I thought would tinker with it and flip it for a few hundred. It had 265k, burned and leaked oil at an astonishing rate. I think it would consume a quart in 650 miles.
I drove that POS for two years in Tampa to work. I never did change the oil. I drove it about 350 miles a week. I just kept filling with the cheapest oil I could find.
After two years, the transmission gave up.
So yes…….. sometimes it’s just fine to just keep adding oil
