I have a 92 prelude s which has 214,000 miles on it. I just had it serviced, and I've noticed a cluster of black, dark brown circles under the engine on my garage floor. Some of them have dried up, others are still liquid, they don't smell like oil, but I dunno. Let me know what u think. Thanx

 

Find a big peice of clear or light colored plastic, then clean your garage floor up real nice and shiny. Take your lude out for a good run to get it nice and warm. Then pull it into your garage, turn it off and put the plastic underneath the engine. Check back in a couple hours and see if you see any drips on the plastic. If they are quite dark and oily, its probably engine oil. If it is lighter in color and more towards the front of the engine, it could possibly be power steering fluid. Keep a sharp eye on the levels of your fluids to see if any of the levels are dropping at a more than normal rate (power steering fluid and brake fluid shouldn't drop at all much) peace
