How Many Quarts

[porschpow]

Is it possible that my "new" crosshatched area is longer than the factory crosshatched area? Mine is a half and inch longer

So Ford did mess up for this era dipstick?

There is a tsb for it if you are so inclined to look it up. You might find it on here or cvn as I attached it to some message years ago.

Yeah from what I heard, I will stick here and not wander off to CVN

Why is this even a discussion?
1. Buy 5 quart jug of oil at Walmart. Buy new filter
2. Drain BOTH oil plugs until they've pretty much stopped dripping. Remove old oil filter.
3. Fill your new oil filter about half-3/4 full with new oil from your jug. Any more and you'll spill oil out the top of the filter when you screw it on. Lube new oil filter o-ring with clean oil. Make sure old o-ring came off with old filter.
4. Screw new oil filter on.
5. Pour new oil onto valve cover. Stop. Swear. Go borrow wife's kitchen funnel. Pour remainder of new oil into engine. Wash funnel. Put back. Don't tell wife.
6. Start engine and run for a minute. Check for leaks. Shut engine off. Let engine sit long enough to drink a beer.
7. Pull dipstick. Wipe. Replace and pull again. Notice that your 5 quarts of oil is showing much higher than the crosshatched area on dipstick. Recall info from GMN about how Ford made a bunch of these dipsticks incorrectly. Swear at Ford. Make new mark with a hacksaw on dipstick indicating correct full mark.

Basically this, but I'd do 4 quarts at first. Make your mark. Add another quart, make a second mark. Between the two marks is normal operating range, below the lower mark is the add range. Problem solved. I picked up a used dipstick at one point that had these marks on it. They were pretty far from the factory marks, but they were dead on. I think I replaced that dipstick and tube when I came across an NOS one for a reasonable price that also happened to have been properly marked.
