Thanks for your feedback brother.
I have drawn part number for dipstick of h22a (15650-P13-000) but I can't find exact description of this part (i.e its lenght, etc). at one of hte vendor site, it states that this dipstick is 23.3 inches long (I assume this includes plastic handle part as well as rubber part following plastic handle). I have searched prelude / h22a forums on other webistes and mostly state that steel part of dispstick is around 18 inches (my current dipstick is also 18 inches in steel part). But there are conflicting measurements thoughtout internet (or I am not looking at right places) and also these forums are mostly occupied by US users who didn't get a lot of JDM h22a but mostly USDM h22a4 which has different oil plan, hence confusion and therefore I am looking to get measurement from a user of this engine.
I am leaning towards your opinion, that my oil pan is causing requirement of more oil and dipstick is correct.
Should I make sure that oil level on dipstick remains on full mark even though more engine oil is in pan?
Currently I am keeping oil level on lower part of dipstick which is requiring around 5.7 liters of oil (Not too high oil in case dipstick is wrong, and not too less oil in case dipstick is correct ).
Thanks again.
