Nope, that ain't "leaded" gas. That is simply distilled petroleum without the addition of ethanol. Nothing new or special about it. Nothing illegal about using it. Older vehicles might see a slight benefit to using it but doubtful.
The only problem I've ever run into using the ethanol blends was the original rubber formulations used on our older vehicles tend to dissolve when subjected to the ethanol. Made for some fun times when the fuel supply hoses decided they would rather be a sponge than a hose.
ALL fuel here in AZ is "oxygenated" (blended with ethanol) to some degree. They actually increase the percentage of ethanol during the summer time to reduce the emissions levels.
Carb'ed engines seem to show some adverse effects during the switch but it doesn't seem to affect the fuel injection vehicles.
Nothing wrong with using it on your older Benz.
