How can the engine oil be checked ...
... when anytime I have tested it after running the engine or tested it in the morning before it is driven the end is smeared with oil from being drawn up the tube?
I just changed the oil.
Based on the dip stick I had 5 - 5 1/2 quarts (impossible to get a clean read).
I drained out 4 1/2 qts. That would be off 1/2 to 1 qts.
I know there is an oil film that hangs in the engine.
I can think 1/2 qt is possible but a quart seems high?
Am I missing something in checking the dip stick (yes I wipe it clean) or should I be looking for some other problem?
This van was purchased used.
Might there be some crud hanging in the oil system?
Would an oil "cleaner" be in order or do I just wait 3300 miles and do it again to see what results?
Note the van oil pressure gauge runs at about 40.

Have the same issue on my 5.7L - wipe it clean & still get the same thing... oil on the stick 'smeared' up past the 'Full' mark.
i think it's capillary action of oil on the dipstick in that long-azz dipstick tube - never really drains out until a few hours has passed after running.
Guess it could be the wrong dipstick in there. Next oil change, add the correct amount of oil, run it & then recheck it the next morning. Mark the dipstick tube w/ a punch if you KNOW the oil level is right but the stick shows a definite level that's off.
Either way - I have the same issue and no amount of 'wiping the dipstick clean' changes it unless the engine has not been run for several hours.
