Is the milky slim in the oil or just on the cap if on cap the moisture is condensation mixing with oil ==if its the oil in crankcase would need to pressure test coolant system and check inspect gaskets--valve train
Blown head gasket or cracked block

The oil filter is most easy to get from under the vehicle. If you have a jack, lift the front passenger side of the car enough to crawl behind the front passenger tire. The oil filter will be on the back of the engine right above the drive axle.
ATTN: The oil filter can be easily mistaked for the transmission filter which is located on the front of the engine on the drivers side.
I am unsure the the exact specification of oil capacity. You can find it in the owners manual or ask the guy at the auto parts store they can look it up. I would put in 3.5,start it let it run for ten seconds then shut it off and check the oil level and add if needed. It wont take more than 4.5

Bad valve seals
Worn valve guides
Pressurized crankcase (oil pan) due to a clogged PCV valve or breather system
Blow-by from worn piston rings
Bad valve seals: The valves are located in thecylinder head above the combustion chamber. Oil is pumped at 50 to 80 psi of pressure into the top of the head, lubricating the valve-train; the valveshave seals on them to stop the flow of oil down into the engine when the valve is open. If the seals fail, oil is allowed to flow down into the combustion chamber and is burned.
Worn valve guides: The valves are guided by a small cylindrical chamber called a valve guide. These guides wear over time causing eccentricity (or slop); the excess gap allows the flow of oil down the valve stem into the combustion chamber to be burned. What about the valve seal you say? Well, the gap is too great for the seal to stop the oil flow, so down it goes to be burned.
Pressurized crankcase due to clogged PCV or breather system:The car's engine is a giant pump, consequently it must breathe. The PCV (Positive Crankcase Ventilation) system does just this, allows the engine to exhaust the excess pressure build-up (which is a natural phenomenon of the internal combustion engine). Carbon build-up is a by-product of an engine and can build up in the PCV system, clogging the breathing passages. This in turn pressurizes the oil pan and pushes oil up into the fuel delivery system, where it is fed into the engine and burned.
Blow-by from worn piston rings: The pistons in your car's engine have seals around them in the form of rings. These rings do two things:
When the rings wear out, the pressure from combustion reverses down into the oil pan, pressurizing it and forcing oil into the valve covers, through the breather system, back into the fuel delivery system, and into the engine to be burned.
You may ask yourself, "What can I do to stop this from happening?" Keep your oil and filter changed every 3,000 miles and keep the air filters changed every 12,000 miles!! This will keep sludge and carbon buildup down to a minimum. Understand that you can't stop mechanical wear, but you can slow it down!

Had the same prob, Replaced the ECTS (Engine Coolant Temperature Sensor)
The ECTS is located to the right of, and just below the EGR on drivers side of motor, there are two sensors that look the same, one has two lead wires (Replace this one) the other (single lead) is for your Temp Gauge.
Cost: Under $20
Replacement Time: 5 mins.
Tools needed: Needle nose pliers to remove connector
13 mm deep walled socket wrench to remove sensor
Rags to soak up any antifreeze that leaks out when old sensor is removed. (try to stay off of the upper radiator hose) and work with a COOL Engine.
SOURCE: Excessive oil use
the time it takes to use one quart is not the figure I need, how many miles does three weeks represent? 1000 miles per quart is ok, less and you will need new rings in most cases, which of course means an engine overhaul.

Saturn says and I quote
there transmission fluid is not to be changed after the first change at 6000 miles.
Now I say it should be changed at every 30000 miles. If changing out the fluid doesn't work then you need to go to a transmission repair shop.
