Thanks Bill. If you change the oil yourself, please measure how many liters come out if you can.

A question to our colleagues “ in the know”. Since our GTs (both 05-06 and NFGTs) are dry dumps. The dipsticks is measuring oil in the reservoir, not the oil pan directly, correct? as long as the level is b/n the marks, should we not be fine?!
Based on my trial and error, 11.5 liters is the magic number. That fill capacity gets me exactly the same dipstick measurements that Bill posted.

Yea, I got one...too
Gene, to answer your question, you are correct. In a dry sump lubrication system one of the objectives is to get the rotating crank away from parasitic losses of churning thru puddles of oil. That robs engine output power. So a dry sump system places a shallow pan under the crank to provide a catch-pan for the oil and it is quickly sucked (scavenged) away from the crank and pumped into an external reservoir tank. The oil in the tank can then be routed to an air or coolant heat exchanger to remove heat and routed to the pressure side of the dry sump pump to be pumped to various engine parts. There are other attributes to a dry sump system beyond the scope of this post.
When you measure the oil of a dry sump equipped engine you are measuring the oil level in the external tank and not in the engine catch pan. Be mindful of various time constraints as mentioned above by Kendall on how quickly you must check the dip stick to obtain an accurate reading. If the level is between the min/max marks within the time limit recommended, you are good!
To complement Biil's post, traditionally the two major advantages of a dry sump is that you can place the substantial weight of the motor lower in the vehicle to improve (lower) the CG and, simultaneously, you can more easily insure continuous lubrication in high lateral G (cornering) situations.

I have had a few customers call and say the same thing......only used 12 l of oil on an oil change....all the ones I have done have taken 13 plus. A question for you guy.....I know it's not in the shop manual but are you warming the car up before an oil and filter change ?

Only done one change on mine so far (second one is imminent) but it took over 13L. Wonder why people are getting differing numbers?

Now that I think about it all the cars that I have serviced were early 2017 MY. I will look into it when I return from vacation. They may have made a change possibly on oil capacity in the new model years.
The Motorcraft Oil Filter chart has been updated.

Be sure to read note 8 at the bottom. Alternatively, definitely do NOT read it and do whatever the opposite of what you suspect it might say is.

It's good to have such definitive information - thanks to champion the correction Dave. Now that we know that that requisite oil filter is single-sourced, per my Post #53 in this thread, either Ford has applied for and received a waiver (pursuant to section 102(c) ), or, by law, they are obliged to provide the oil filter free of charge to owners.

Ok now that I am back from vacation i made a call to the Ford GT people and inquired about the discrepancy of oil refill differance between one owner to another, so the question I have for some of you guys is where are you getting your oil from ? I read that sinovac was possible getting his oil from the UK ? also what are you using to measure the oil being replaced in your cars ?

One of the questions The Ford GT people asked was the capacity of the jugs being purchased because US quart and a UK quart are not the same so that maybe were the missing liter is from. This is why I was asking.
It's really only a very simple question (or two).
1. With an oil and filter change - and presuming that Ford's recommended procedure to pre-fill the oil filter is followed, what volume of oil should then be added? (Answer can be in whatever units you want - easy enough to do the conversion.)
2. For grins, does For recommend checking the oil level with the dip stick fully threaded in place or just just at the beginning of the threads?
