The number of quarts always puzzled me. But as I wrote, my book says five (not counting a filter) and it shows full on my dipstick. I have a second 235 and it takes five and both dipsticks show full. What adds to my confusion is that the book says U.S. quarts but being up north we don't get quarts only litres. If I recall 5 quarts equates to 4.78 litres. On another note, if you buy a gallon of paint, you don't get a gallon. You get 3.78 litres. Paint cans are made in the USA to gallon sizes. Metric Madness!!!
