HI, Hope you have better luck today. AS FOR YOURPROBLEM WITH YOUR QIL LIGHT ON AND LEAKING OIL. 1 - CHECK YOUR ENGINE OIL TO SEE HOW LOW IT IS ON THE LIO STICK, IF IT IS LOW ADD OIL. 2 - CHECK YOUR OIL PAN FOR LEAKS, SOMEONE COULD HAVE LEFT THE OIL PLUG LOOSE AND CHECK YOUR OIL FILTER TO SEE IT MAY BE LOOSE.

Steering wheel wont move so i cant start the car

Rocking it back and forth will sometimes release a jammed steering wheel. It happens sometimes if the key is removed too quickly and the wheels are not straight. You should check the internet to see if your car is one of the many that have this problem and that have a recall issued. MAny GM and Saturn models have stuck keys, etc.
