Back in college days in 1969 we used aluminum trays with red hot charcoal, slid under the oil pan to warm it up. Back then impoverished students did not have "plug-ins" for electric block heaters.
The charcoal thing worked well if one monitored it. I can imagine boiling Pennzoil was not conducive to good lubrication. But our vehicles were Junkers (an early Yugoslavian import, before the infamous Yugo). And if they blew up, the city of Saint Paul towed it and there was no penalty for forgetting about the car. The City just scrapped it after a month.
