How likely is it there is at least microbal life on Titan if there are oceans there?

The big problem with the possibility of life on the surface of Titan is that methane is not a polar liquid, and a lot of biochemistry works because water is. It's also possible that reactions would be too slow. However, Titan does have a liquid water mantle so life in that is conceivable. Then again, maybe all we know about life on Earth is just about life on Earth and doesn't apply elsewhere.

The oceans on Titan are methane. Earth type life couldn't survive in liquid methane. I don't know if some other kind of life might be there.

We don't have much of an idea... the liquid there (more like large lakes rather than in oceans) is methane and ethane; and the severe cold is going to affect how chemicals react as well... My *feeling* is there would be no life there, but that's an opinion for now; I think it's simply too cold for life to form. But... that could be wrong...

Life on Titan would have to be built on a complex chemistry about which we have no idea and which very well might not exist.
Earth-like life based on liquid water might be possible on those moons with water oceans (Europa has much more ocean water than Earth) and volcanic activity.

We don't know. There are no oceans. There are lakes and streams of of methanol and ethanol. Because it is so cold. on Titan more than one astrobiologist has hypothesized that life might not be microbial but pretty large on How the Universe Works and other shows on the Science and Discovery channels. Or as suggested in the Wikipedia article hyper linked below, have a different kind of chemistry than life in earth. Liquid water, which may be underground, would still be needed. Check out the sources in the Wikipedia article.

The "oceans" consist of liquid methane instead of water. The temperature is minus one hundred and eighty degrees, which is way way too low for the complex chemistry that defines life. Like every other object we have ever examined in space, Titan is sterile.
And just out of interest, of all the properties of the fascinating moon called Titan, why single out the most improbable thing to ask a question about. Honestly, if you are interested in life, including microbial life, why wouldn't you be discussing the Amazon Jungle, Kelp Forests, or the remnant savanah lands of Africa with biologists, instead of puzzling over boogers in the most impossible place imaginable with astronomers?
