Well, I don't think the makeup will cause greasiness in itself, though if you're sensitive, the wrong foundation may cause breakouts. But what you want to keep in mind is that liquid makeup along with already greasy skin may seem greasier after a few hours, slipping off your face (even with a mattefying powder on top.) Personally, I have greasy skin but stick to the liquid foundations anyway, because I also have uneven colors, small breakouts and scars, which liquid makeup hides better (I usually use a primer to help dealing with the grease, esp. in summer.)
If you don't feel like you need tons of coverage, go with a mineral powder foundation, they're usually kinder to the skin, and will help with the grease (getting a good brush for powder makeup is key). You can also buy blotting papers in most makeup stores, they suck up the excess grease without messing to much with the rest of your makeup.
