Oil dipstick...and floats

[CF-HEW]

Hi everyone,
I remember reading on here about 172 dipsticks in 170s or vice versa and the markings not being accurate when they are swapped due to the airplanes attitude when parked. I just put my 170 on Edo 2000s and it dawned on me that the dipstick readings may not be accurate as the aircraft appears to be more in a nose low attitude. What do you guys with floats generally keep your oil levels at?

I don't have floats, but in the 1950 Owners Manual under operating details it says not over 7 quarts for seaplane operations. There is a copy of the of the Owners Manual in the members section.

John is correct. My dipstick reads 1 quart lower than is actually in the engine. 53 170B on EDO 2000

Thanks guys, I figured it would read a little lower but was unsure how much. I've been keeping it at about 5 qts.

I just changed my oil and filter, put in 8 qts, ran engine looking for leaks, shut down and the dip stick reads 6.5 qts ('53 170B on EDO 2000's).

The presumption being that you have the correct 170 landplane dipstick part-number and the oil filter refilling with about 1/2 quart?
Good info.
