I don't claim to know everything about the damage that could or couldn't occurr but I am only posting my experience and what I have heard.
My tank holds 150 gallons of diesel I get between 8 to 9 miles to the gallon. PV is about 1000 miles from Nogales where I fill up with ULSD. That gets me about 1200 to the tank. So after I use quarter tank I fill with Mexican diesel and fill again when quarter gone. Fill tank at final destination and that gets me back across border.
My rig has a little over 30,000 miles on it and 1000 of Mexican diesel, each trip,my opinion it will hopefully survive.
