Welcome to the forum!
I know we've got some members that have used an oil bypass kit on the older trucks.. you're probably the first here that is looking to do it on a 2020.
I've seen it posted here a few times were the dealer said they had gas in their fuel, and I would agree.. I think you would of had issues since you drove it that far. Now, it's your word against the dealers.
How long ago was it before you filled up? Usually if it happen 24 hours out from you finding out you had gas in your tank, go back to that same pump and pump out 5 gals, have it checked. If at fault, make the station pay!
