OFFERED FOR YOUR CONSIDERATION: This problem may come from "unclean" distributor refueling practices when delivering to local retailers which is where we buy our fuel. Large truck stops are probably our best bets but convenience always seems to win out when we fuel and some of us have little choice. I know this is not a "good news" item but only a possibility of how fuel can be contaminated. That being said, it's hard to believe contamination of Im4yoters fuel would show up after 300+ miles since last fueling.
Now then, does gas sink below diesel or float above it in our tanks? Or does it mix with diesel? I believe our fuel pickup is at the bottom of the tank so if gas floats above diesel, then it wouldn't get picked up and into the fuel system until diesel supply was sufficiently consumed. Not being a fluid engineer, I'm just speculating. Perhaps someone who has a few "engineerring qualifications" would chime in on this speculation. Cummins should also be able to tell us how much gas can be tolerated in our fuel. None? A little? Lots? Anyone been through this exercise? Inquiring minds want to know.
And finally, anyone reading this thread should make it a point to use a locking fuel cap and give the dealer only the ignition key when in for service. Spending $15 for a locking fuel cap on a $5k engine is some cheap insurance. And I know, Elvis has already left the building for this episode.
