Just wondering if anyone has any interesting/ amazing stories about engine survival - motors that shouldn't have kept running, but did, and what was done to keep them going...especially what additives were added to 'fix' them..... My father had an 1989 Toyota Tercel, and I came home one day to find the drain plug and contents of the oil pan in the driveway, and him out doing downtown errands...dealer didn't put plug on tight. Drove all day on no oil, oil light only flickered a couple of times, according to him, and after being towed to the dealer and re-filled with oil, car ran fine for another two or three years, until wrecked in an accident. Used a bit more oil than before, but never blew up. Toyota reliability at its finest, I guess! Another one I heard was a guy with an old Subaru with spun bearings...wanted to keep the car going as long as possible for as little as possible, so his mechanic filled his oil sump with pure Restore (4 litres!), ran the engine for a half hour, changed it to engine oil, and sent the guy off to drive the car for another year or so, before it was traded in! Apparantly ran fine... Another one I read about was a person who had an old escort with a cracked block and spun bearings that filled his engine w/90wt gear oil and drove the car for another 10,000 miles.... Any other stories like this out there?
