Yes it’s true gas in a diesel can be very troublesome, but as long as it’s not run for long with a gas/diesel mix there shouldn’t be any long term issues.
This is accurate. The major issue is when you run a few gallons of gas in the diesel. With a small percentage of gas in it, it will still run and that's where the trouble is.
Gas does not have the lubricity of diesel and as such, the gas that's in there washes down cylinder walls and can damage injectors and other parts.
Better to have a mistake and fill up a full tank of gas in the diesel because it simply will shut down and won't run very far at all.
Diesel in a gas, not a big deal, flush it out and you may have a smoke show for awhile, but it'll eventually clear itself out. Harder to do though as in most cases the diesel fuel nozzle is too big for the gas fuel fill.
