Oil measurement question

[Skippydiesel]

everyone missed the point so I will make it again. Pushing "the dipstick back in" is capable of yielding two different results. If the protrusion on many oil caps, is placed into the notch on the filler, the dipstick will go further into the filler tube than if it is pushed down out of that position. Double check the dipstick to see if it has such a notch and protrusion. The filler caps I have on all my oil dipsticks have a setup like that.

Maaate! - You miss the point. Just check where your dip stick Max level will be on the OUTSIDE of the tube. This will tell you if the cap should be screwed down or rest on the top.

I have a 1994 Briggs 18hp opposed twin engine (model 422707, type 1263-01, code 9403045B) on a Huskee garden tractor and am unclear on the correct oil measurement method. The manual states that 48 oz is the oil capacity for an engine without a filter, and 56 oz for one with a filter. It also states to place the dipstick in the oil feed tube to measure the oil level, but does not state to thread it snug and remove to read the level. The tractor engine has no filter, so 48 oz should fill the sump to the Full line on the dipstick. However when I follow the manual instruction to measure the oil level after an oil change, 48 oz raises the oil level to the Add mark at the bottom of the crosshatch area on the dipstick. When the dipstick is fully threaded down, 48 oz measures at the Full mark on the top of the crosshatch area. I do not want to run it on low oil or in the alternative use too much oil. Which measuring method is correct for this engine? Is 48 oz the correct amount of oil when it lacks an oil filter?
Thank you for any assistance.

About that lack of filter. "The 422707 series uses full-pressure lubrication. Oil-filter adapters (and remote/cooler options) appear in parts diagrams for type 1263-01 as available components, not as standard equipment on every unit. Some engines left the factory without the filter/adapter installed.". If this engine is at all important to you I'd get the filter kit. A Ford study back in the 50s showed an 800% increase in bearing life with a filter vice not having one.
