"When your engine is running you will need one more quart of oil to wet the inside of the engine. In addition to that you will have somewhere between a ½ quart and ¾ quart of oil in suspension around the rotating assembly."

I recently installed an Aviaid pan that has a 6 quart capacity. Prior to installation I filled it with 6 quarts of water to confirm that the fluid is just at the baffle. Am I to understand that an additional quart of oil is to be added to the stated capacity from the manufacturer to account for oil that is suspended in the engine when running, bringing the total capacity to 7 quarts?

I have another idea. I don't want to drop the pan if I don't have to. If I insert an oil extraction hose into the engine via the dipstick tube, I can feel for it hitting the top of the baffle. Once there I can try extracting. If oil comes out I would assume the oil level is above the baffle which is no good. Once that procedure is done I can measure again with the dipstick and create a new fill mark? Crazy idea?

Sounds interesting. Tube would need to be straight and have some decent rigidity to it (i.e. doesn't bend when it hits the baffle).

You are reading the tea leaves correctly SBSerpent. Between what is required to wet the engine internals and the oil in transit back to the pan you approximate a quart. A big block with more internal real estate will take a bit more to do the same job. The "extra" quart you add to the engine just brings the oil level in the sump back to where it was before it lost the oil to wet the engine internals.

I pulled the pan to inspect the baffle to see if I had the old style or the revision. It seems I have the old. Moroso is sending me the revised baffle. I attached pictures of mine and the revision for those who are curious. The first is mine and the revision is second. You'll notice the oval relief hole so it allows the dipstick to seat fully. The third shows how my dipstick scraped the pan causing the stick to arc and give a false reading. I also found that I do have a windage tray (last photo). It's a Moroso product that is required when installing their pan. now that I have the pan off I can experiment by pouring water until it comes to the bottom of the baffle and then count additional quarts for filter, oil in suspension, etc. By looking down the baffle I can't see how more than a few quarts can fit in there to not exceed the baffle height. Using eschaider's previous calculations, plus another 1/2 qt. for the Motorcraft filter, that would put me at around 5 quarts total. Doesn't add up. Maybe that baffle area holds more than the eye can see. I'll try and see what happens. Does the windage tray throw off any of the mentioned calculations?
