Are you asking because you're looking for something cheaper, something better for the engine, or something better for the environment?

Some companies are now offering reformulated partially recycled stock oils, which are arguably better for the environment. Whether they will properly protect your engine is another question, and since you haven't told us what kind of car, truck, boat, motorcycle, locomotive, helicopter or other contrivance you're contemplating for such use, it's hard to guesstimate.

If you're simply looking for "something cheaper," you're likely going to end up spending more money in the long run. Modern MB vehicles are designed for specified synthetics that have the proper additive base, and those will save you fuel and protect your engine; picking a non-spec oil is a crapshoot.

Good luck.
