From https://en.m.wikipedia.org/wiki/Composition_of_Mars

Based on these data sources, scientists think that the most abundant chemical elements in the Martian crust, besides silicon and oxygen, are iron, magnesium, aluminum, calcium, and potassium. These elements are major components of the minerals comprising igneous rocks

The exhaust from an engine running on magnesium would (I would think) be on the sooty side.  The carbon would exhaust as soot, and magnesium oxide would (presumably) float for some time in the atmosphere as a fine powder. 

To my surprise, magnesium oxide is used on Earth for medical purposes:
