I have a habit of dumping ATF in my Benz fuel tank. Lil extra lube for the old injection pump that was never meant for ULSD. Fact, few bottles in the trunk. That will make clear, red. As Newly said, how they gonna prove it? I doubt they'll sent it to a chemist to see "what" made it red, dye ot ATF...... Hypothetically speaking, if i bought off-road, i'd by it from a non-attended station and just fill up jugs, not the vehicle, and fill it up in the privacy of your own place. But thats all hypothetically speaking of course!. I know around kansas, K-DOT likes to go to ex:// rodeo's, auctions, events of the country folk variety and dip tanks while everyones busy
If a guy wanted to be real sneaky, make a false filler tube with a small amount of clear diesel in it
I doubt a diesel benz would get much attention:angel:
