I've never had an MRE that tasted like any type of Fuel,Though I've had some that,If I had Taken more than the,Few bite's that I did,I felt I'd become Violently Ill! I had to eat MRE's for Months,So knowing what to mix with them,Can make Life Much better! Toothpaste & Alka Seltzer with a bit of water,Usually Got rid of The Slime!The Slime is on the roof of your mouth,after eating them!
