Hey guys, I was just cruisin on fmcdealer.com (the website we use at work) and strolled across this TSB that i think you would find interesting considering there has been plenty of contraversy over oil capacities on the boards... maybe this will shed some light on why over filling is a bad idea

ISSUE:

Reports from the field indicate incorrect or low engine oil levels are being found at Pre-Delivery Inspection on new vehicles received in dealer inventory. In most cases, the level is being misinterpreted because the fluid fill mark on the stick is not touching the top hash mark at the upper limit (or MAX mark), or is partway down the crosshatch area.
ACTION:

Ford is in the process of standardizing the markings across all vehicle lines. Current markings shown will be upgraded to a refined marking, shown in Figure 1 (http://www.fordtechservice.dealerconn ection.com/pubs/content/~WT/~MUS~LEN/3587/tsb03-08-03.htm#fig1). Both markings will be used in production over the next few years. Oil levels will still be recorded in the crosshatched area of the blade, between the upper and lower limit holes. Vehicles shipped with engine oil levels falling within this area are acceptable and do not require topping off. Oil fill quantities are precisely measured at the plants and account for slight variations that may occur in oil pan volumes, indicator length, and pressed-in locations of the indicator tube into the block. For customer use, the markings continue to serve as a guide to refilling the engine to the correct initial fill volume with filter or, to top off the engine when it is determined the level is below the lower hole.
SERVICE INFORMATION



Ensure the vehicle is sitting on level ground. Set the park brake and ensure the transmission selector lever is in PARK position, or in FIRST gear on manuals. The engine must be OFF.
The best time for determining oil level is before the engine is started and the oil has had sufficient drainback time to the sump. If the engine has been running, allow it to sit for a few minutes turned off. An oil drainback period is required before taking an initial reading.
If the level falls below the lower hole, fill with one quart of oil. If one quart is insufficient to raise the level above the mark, add oil until it records within the crosshatch area. Use caution during this procedure as some time is needed for oil to drain down through the drainback passages in the cylinder head, to the oil pan. Adding oil a quart at a time repeatedly without sufficient drainback may overfill the sump.
If the oil level falls between the upper and lower hole do not add more oil. Adding an extra quart could cause overfilling and may result in aeration (foaming) causing eventual damage to vital bearing surfaces and moving parts inside. Overfilling will require some oil to be drained out until the indicator shows the level between the upper and lower holes of the blade. DO NOT expect the engine to "consume" the extra oil back down to the upper oil fill level hole, or consider it as extra lubrication protection for the engine.

I don't ever recall any controversy over ^^^^. I think most if not all on this board would agree that filling above the FULL line is a bad idea.

Most of the oil controversy that I have seen here pertained to "which" oil and "what" weight was best. :P But I ain't gonna start that debate again. ;)

When I purchase a new vehicle I always check the oil before leaving the dealership.:D Same goes for oil changes.

theres a thread with pictures showing that the oil pan off of the car can hold "X" amount of quarts and people believed it was a good thing to over fill since there was room i post the link in a second

The factor that should be used to determine you need more oil capacity is if you have ever had a loss or drop of oil pressure at high RPMs. If this happens, then you might need to use a higher capacity oil pan. Putting more oil into a stock engine is a bad idea and can lead to problems where initially there were none. Overfilling your engine is a bad idea.

What VAmarauder03 posted above is VERY good advice.
