When I worked at a prison years ago, the perimeter security cars were driven/idled 24 hours a day, 7 days a week, 365 days a year. They would rack up 200K, 300K miles, with INCREDIBLE idle time. And they only changed the oil very occasionally with bulk 15W40.
This is the exact way our service vans are operated. Some days they run as long as 20 hours if two shifts use the truck. We simply do not shut them off unless we are going to be stopped for more than 20 to 30 minutes.
They routinely run to ridiculous mileages...
Dumb question - but do you just fill them with a 5 gallon gas can while they are idling for 20 hours?
