'99 Ironman dipstick length...

The Amsoil filter that I'm using is the same size as stock. Plus it'd have to be one BIG filter to swallow up a full extra quart, plus of oil....

Wondering if the online specs (capacity) are wrong. 4.2 / 4.3 VS 5.3 or 5 1/2?

Anyone else find that they need 5 1/2 qts of oil with the oil/filter change?

With that many miles, is it possible a few engine-block/head oil passages might be partially clogged and preventing full oil capacity drain-back into the pan?

I just checked in the shop manual (page 0B-11) & it states:

Oil change with filter change: 5.0Qt (4.7L)

Oil change without filter change: 4.3Qt (4.0L)

So now you only need to account for that extra 1/2 quart of magic oil

& I challenge anyone on the forum to pour 0.7 quarts of oil into one of our dinky-doo oil filters & have it all fit.
