Two part question...

[CrackRabbit]

Part one Oil Spots.
I noticed a rather large oil spot (think pancake sized) on the concrete driveway at my new house this morning, something that wasn't there when I had parked there the night before.
I knew my car leaked a bit of oil, but nothing that major. What is the best way to clean it off and maybe help prevent new spots from sticking until I can implement part two of my question.

Part two.
1991 Infiniti G20, 4cyl 5-spd 172000 miles
The oil leak is the final straw, I was going to get the water pump and clutch done within the next two weeks. I now fear that the front crankshaft oil seal is leaking due to the placement of the oil spot on the ground. I don't feel like putting three $4-600 repairs into it in such rapid succesion and it still needing other less vital work. So I start the hunt for something newer.
Quick searching shows a few models I am interested in In my price range $6-7000.

Let me list off a few that I am looking for info for...

2000 + Chevrolet Impalla and Malibu(Classic) and Pontiac Grand Prix, Buick Century/Regal
2003+ Ford Focus
2003+ Hyundai Elantra
2002+ Ford Ranger
2000+ Nissan Sentra and Altima

Just looking for personal experiences mostly.

TIA,

CrackRabbit

Pressure washer, cat litter or superclean can work to get the oil spot.

Way back in the '60's when I was in college, I worked for a Union 76 station in San Diego.
Every evening when we shut down we would sprinkle stoddard solvent from the bulk chemicals tank onto the comcrete aprons between islands
and mop it out to spread the liquid, then dust it with grease-sweep, a burned rice hull ash, then sweep it out to absorb the solvent.
after is had dryed out, we swept it up and the resulting surface was immaculately clean - it always looked like fresh new concrete, even ater several years of this cleaning method.

sprinkle powdered laundry detergent on the oil, spray simple green on it to moisten, and rub in with brush.
rinse with a pressure washer.

To help prevent...seal with a concrete sealer (Thompsons, ect)
