Engine Oil

Check Engine Oil by using the dipstick. It is usually located right above or to the side of the engine. It usually has a bright color (red or yellow). The Dip stick is a long steel rod that is pushed into the engine oil compartment and checks the min and max levels of the engine oil.

If your oil level is below the MIN (Level) you need to add more oil (Remove cap E, and poor extra oil in)
If your oil level is above MAX (Level) you need to drain oil from the engine by turning a screw underneath the car to drain excess oil out
