Take it to the snowplow truck that is parked to the right of the School. The driver will say he needs exactly 4 liters from the 10 liter bottle. For this, you will need Sweaty's dog dish from Rodrick's room in Greg's house.
When you use the fluid, fill the dog dish (3 liters) from the 10 liter bottle, then pour the dog dish into the 5 liter cup. When you fill the dog dish again (another 3 liters), you will have 4 liters left in the bottle.
You bring it to the guy with the snow plow and then pour it into the dog bowl. Once it's in the dog bowl pour that into the cup. Then pour more into the dog bowl and 4 ounces will be left in the original container.
