  2. I remember back in the early 80s when they were trying to push “Gasahol” a Corn Based Gasoline. Same price as regular gasoline but cut 1/2 corn alcohol(?) I tried it a couple of times in my 1966 Mercedes-Benz 250S which was touchy with fuels.
    On the highway it was fine, around town it was a bit sluggish, Also when you would open the 4bbl you would get some pinging(I was heavy on the 4bbl)
    But I did notice with the tail pipe when I used regular gasoline I would get a dark gray tint inside the tailpipe, with the gasahol… A light Tan color which tells me a cleaner burning fuel. Also less Carbon deposits on the Spark Plugs. Those older Mercedes use Sodium filled Valve’s designed for “leaded fuel” so I always kept up on it.
    I used it for as long as it was available,especially trips from V.A.Beach to New York. Never had a problem.
