Is it possible to chemically analyze an engine's emissions to detect presence of oil in the fuel? I am losing a lot of oil but it's not dripping when running to indicate a leak. So I would like some chemical analysis to support for or against the suspicion of burning.

Yes it is possible but it requires special equipment called an "Exhaust Gas Analyzer". Call around to some local shops to find one that has such a setup.

They can detect excess oil, coolant, and other issues. Many state emission testing centers use these also.

Here is a link that describes some of the measurements that these can make:

Specifically it says:

High CO levels indicate partially burnt fuel or oil

You can also often tell there is excess oil being burned by inspecting the spark plugs. An oily and carbon-encrusted electrode is a good indication of an oil burning problem.
