Step 1: Fill the three gallon oil using 3 gallon container and pour it in 5 gallon container (Current Status 3:0 5:3) .
Step 2: Fill three gallon container and pour it in 5 gallon container remaining in smaller container would be 1 gallon.

1) fill 5 gallon container ---------------> 3 gallon container have 0 lgallon and 5 gallon container have 5 gallon water

2) pour water from 5 gallon container to 3 gallon container --------> 3 gallon container have 3 lgallon and 5 gallon container have 2 gallon water

3) empty 3 gallon conainer -----> 3 gallon container have 0 lgallon and 5 gallon container have 2 gallon water

4) pour water from 5 gallon container to 3 gallon container -----> 3 gallon container have 2 gallon and 5 gallon container have 0 gallon water

5) fill 5 gallon container -----> 3 gallon container have 2 gallon and 5 gallon container have 5 gallon water

6) pour water from 5 gallon container to 3 gallon container -----> 3 gallon container have 3 gallon and 5 gallon container have 4 gallon water

7) empty 3 gallon container -----> 3 gallon container have 0 gallon and 5 gallon container have 4 gallon water

8) pour water from 5 gallon container to 3 gallon container -----> 3 gallon container have 3 gallon and 5 gallon container have 1 gallon water

First fill the three gallon container and pour in the 5 gallon container and again fill the 3 gallon and pour in the 5 gallon so there will be 1 gallon left.
