How many gallons of water does my Coleman Model 550 Sahara hold?

inside pool wall has fill line

If the barrel is the same size from bottom to top, measure the height and divide 550 by that number. That'll give you the gallons per inch measurement. Take that number and multiply it by the 14 inches and you'll have the gallons contained at that level. This will only work if the barrel is the same diameter all the way up.

The Series 80 washer has a max capacity of 20 gallons. At the lowest water level setting you would have between 14.5 and 15 gallons.

You should be able to download a manual from this site:

The VLF1582019 is a 20 gallon model but you should confirm if this is the model number of your unit.

Compressor oil is less demanding then cars, but car oil works fine. Normal 1W-40 would probably work the best.
You would hardly ever have to change it either, because there is no water, soot, or acids produced in a compressor, as there are with a car.
