1999 Chevy Malibu backseat question

I have a garage queen that has only been driven about 800 miles in past 6 months. The last oil change (semi synthetic lubricant & mobil 1 filter) was also done 6 months ago. I know the manual recommends an oil change every 5K miles, but for garage queens such as mine, when should I change the oil?

My 2005 Ford Focus heating/air blower doesn't work at all. The fuse is good. I took out the blower, and put a ground and hot wire to the blower motor and it works. I checked the wiring coming to the motor and one wire is hot, as long as the ignition is on, no matter what position the blower motor switch is on. Even though that wire is hot, when I put the connector back on the blower motor, nothing happens.....even though my tester says their is juice coming to the connector, and when I hot wire the motor directly it runs. The connector seems to go right on to the leads to the motor, nothing in between...but it doesn't run. HOW CAN THIS BE?? The manual said something about a resistor.....but I can find nothing. It's only two fat wires to a connector...that plugs into two leads that carry the juice to the motor. Again, when I hot wire it....it works, When I plug in the connector that shows there is electric, there is nothing. HELP PLEASE!! :)
