The units used would usually be liters, or sometimes milliliters. That's a measure of volume; if it is the mass you want, you would measure in kilograms.
Milliliters would be the best metric unit to measure the amount of salad oil in a large bottle, as it provides a more precise measurement for liquids compared to larger units like liters.

Since water towers generally have a very large capacity, I would say that cubic meters might be the best bet. You can measure the total volumetric capacity of the water tower in cubic meters and then determine the volume of water that is currently in the water tower. However, an amount of water can also be measured in liters.
Three metric units used to measure mass are grams (g), kilograms (kg), and metric tons (t). Grams are typically used for small, everyday items like fruit or a pencil. Kilograms are commonly used to measure larger items like a person's weight. Metric tons are used for very large quantities like shipments of goods.

Gallons (standard) or liters (metric).
Well that would depend on the size of the plastic bottle. If the bottle is large use litters or "L" for short. If the bottle is small use milliliters or "ml" for short.
Metric tons measure mass or weight. 1 metric ton is equal to 1,000 kilograms or approximately 2,204.62 pounds. It is commonly used to measure large quantities of goods or materials.
