So I've been around for years on here and know why it's a good idea to run slightly above full on the dipstick.

But let me get a little more picky here. I've read people say they run 1/2" above the full mark. Really, a full 1/2" ??

Seems like I can run 1/4" high and be fine, but if I go up to 1/2" high, the engine burns the extra oil off or something, as the oil level drops back down to like a 1/4" high.

And No, I do not believe there is anything wrong with my engine, it does not further burn any oil. I can change my oil 8k miles later and still be 1/4" high.

Thoughts?
 
Are you sure they are talking about a half of an inch and not a half of a quart?

Many members run 6.5 quarts and then see where that falls on the dipstick as their point of reference.
 
Some people even run a full quart over when tracking. I thought that if you go over 1/2 quart that the crank will be in oil... theoretically loosing some power. I ran 3/4 - 1 full quart for a while... but a few oil changes ago I backed down to 1/2.
 
I was once told the only dumb question is the question not asked so here goes.. This 1/2 quart extra of oil applies to ALL Duratecs, or just the SVT model?:shrug:

all 2.5L duratecs or 3.0L engines with 2.5 heads ... but its a good idea for all of them ...

A while back I asked at what level would crank whip start happening, and I was told somewhere around 7.5 quarts, maybe a little less.

hmm I am running 7 Qts in mine, but then again I have a oil filter relacation kit that uses a FL-1A filter ... and that brings the oil level to the top of the full area
 
I have read some people saying 1/2" above the min line on oil as well. I figured they were wrong and confused with the antifreeze. 6 1/2 quarts here.
 
The manual for my SE says 5.3-5.8. Generally 5.5 puts it on the money, and I run the full 6 quarts in the motor. So basically running 1/2 extra quart. But I have the non SVT motor. :shrug:
