I have heard that putting sugar in my fuel tank may lead to my vans not working anymore. This is an outcome I am looking to avoid.
I use these vans to transport children, who I usually pick up from sites about a few miles out. I would be really miffed if those vans were disabled in such a way that they were not able to make it to those children.
Are there any other actions I should avoid taking with my vans? I really wouldn’t want to cause damage to them in such a way that they would fail before the children got inside them.
Make sure the engine oil drainplug is tight and not leaking or even removed entirely.
Engines don’t last very long without oil in them and running them without oil causes permanent damage and even catastrophic failure.
