These newer diesel engines are very sensitive to water in the fuel. You don't even want to go there.
Good point. I knew that, but on one trip, due to my bad planning, I had no choice but to fill up at a seedy-looking out of the way gas stop on a secondary road in the hills of Pennsylvania.
We made it onto the interstate and into NY state, when the truck suddenly went into "Limp" mode and I could barely make it into a small town that had a GM dealership,
The dash info system told me I had zero fuel filter life left - and it just happened I had checked it that morning and it was showing 55% left so I figured chances were pretty good I had picked up a load of and fuel (algae growing?).
I told the GM dealer that and asked if they would change the filter and if possible dump m the remaining fuel which was down to about a quarter tank - they were not sure if they had the ability to dump the fuel.
When we return to collect the truck in a couple of hours, they had changed teh filter and the truck was fine. they said they did not dump the remaining fuel as it looked ok (I don't know about that!)
In any event we had no further problem, so my money is still on bad fuel.
I now carry a spare diesel fuel filter with me as well as tools to change it (there re youtube instructional videos.) That probably guarantees I won't have the problem again and will never need my emergency filter! I also carry an OBD 2 scanner to read and cancel codes.
So now I am all the more careful to do my best to buy fuel from stations with high turnover!
