Interesting. When I picked up my truck it was full of fuel and def however there was white powder all around the def filler location I guess they spilled some when filling it up.
Road salt tastes like salt, DEF tastes like burning!Hope it was just crap getting thrown up when we had snow last week (possible it could have been road salt I suppose).
It was a joke, reminds me of the days when a mechanic (not this one) would taste how sweet you engine coolant was to see if it had enough antifreeze in it.No cartoon "burning".
Why in the world would anyone taste road salt or DEF?
Now don't answer..."to make a comparison".
