I recently changed the engine oil of my SHO 3.0L. I have a question on
how much oil should be added.

When the engine is still (turned off), I checked the marker and the oil
is in the middle of Min ~ Max. However, when I turned on and warmed up
the engine, the oil dropped below the Min marker. I'm confused about
in what situation I should check the oil level. I read the "Haynes' Manual",
and it says "engine shut off, check ......". However I do remember from
somewhere (I forgot the source, sorry) that the oil level should be checked
when the engine is warmed up.

Could any professionals here give me some tips on how to check the
engine oil level?

Thanks

A 3.0L SHO takes 5 qt. total, and as for adding add about 1/4 of a qt. and recheck it. If it is still low add another 1/4.

You should wait a few minutes after killing the engine before checking the oil as it takes time for it to run back down to the pan. Checking the oil on a cold engine is most accurate.

Agreed. Check the oil level after a few minutes for it to run into the pan.

I'm not familiar with the SHO 3.0L, but if your oil filter is mounted horizontally and the oil filter is a cheap one without a check valve, you could get quite a bit of oil draining back into your pan.

I've never noticed that big of a difference on my '97 3.0L SOHC.
