Oil Change and HPOP Oil Reservoir

[jd4010]

So....I'm proudly changing my oil over from whatever Ford put in it during a recent repair job to Amsoil 5-40 and, not remembering exactly how much I had to put it, did a wonderful Google search on 6.0 Powerstroke Oil Capacity and ran across a series of threads regarding the HPOP reservoir.

According to my reading, there is a reservoir on these engines that holds like 3 quarts of oil. So if I read this all correctly, changing 15 quarts out means that the new 15 quarts will mix with the 3 quarts that remained in the HPOP reservoir. So my nice Amsoil will quickly become tainted with this old dino (or whatever) oil placed in by Ford.

Is this true or is this for the 7.3 motors only? I'm bumming....

It's true, with our HPOP reservoir there will be some old oil mixed to the new. Unless you have metal debris floating in the oil, I wouldn't worry about it. It's not enough to cause issues.

I think it hold .89 qts on a 6.0. If you add up all the places a 6.0 holds undrained oil I suspect it would be less than 2 qts. I still wouldn't run Amsoil more than 5k without at least sending some off to Blackstone sending a small sample to the lab is cheap insurance.

The HPOP reservoir holds about 1qt. When swapping the oil cooler and screen out get the old oil out and add the quart before you close it up.
