Reminds me of some of the ridiculous things we have probably all done over the years.
Before retirement, bought a 2003 Triumph Americain motorbike, left work and called in the local servo, that used to topping up the diesel Prado from the same pump and being a million miles away at the time, topped the tank off. Only got 100 yards down the road, started missing, burping, pig-rooting etc, back to the workshop, one of the mechanics asks, "Didn't put the wrong fuel in did you?"
"No, of course not! What do you think I am? Stup............ " Rip the filler cap off and took a whiff, sure enough! Luckily drained the tank and carby's, fitted two new plugs and away she went with no apparent ill effects. Workshop guys gave me a bit of stick for a while, "For a bloke who's been around trucks and earthmoving gear all his life, you sure stuffed that one up!"
As they say, live and learn, some of us just live!
