I can beat that.
I once bought an A40 with a very worn engine. I needed the body to fit my very good engine and gearbox because someone had T-boned my first A40.
When I went to change the oil the first time, I found that the sump plug had been brazed in.
Around town in Armidale, the oil consumption was almost acceptable as the oil never got warm. On the first trip to Tamworth, I found out that the brazed sump plug wasn't really a problem. I half emptied the sump before I was even halfway there
There was no need to change the oil. The oil didn't stay in the engine for long enough to become contaminated. :p
