I change dino at 5k and syn at 7.5-8k. I will be pulling a sample after this 5k run of MC oil for reference. My engine seems to run high in iron content, I'm curious if this run on dino makes any difference.

Just picked up 6 bottles of Motorcraft oil and two filters myself. Tough to switch brands since I have been using Rotella for years now. But it's also hard to resist a 5 qt jug of MC for only a few cents more than 4qts of Rotella. I will be interested to see my labs when the time comes.

I have a statement with a question. Running a 2000 F-350, bone stock, 240k miles. I changed my crankcase oil. Drove 15 miles looked at the dipstick and the oil still looked like new. Watched the video mentioned in this post, went out with my home made vacum device with a glass catch jar and sucked out nasty black oil from the HPOP resivoir.
Question: Why doe's the oil on the dipstick look new and the oil I've removed from the resivior look black? Shouldn't the HPOP resivoir oil look new after 15 miles of driving and circulating? It was very black not even close to being diluted with fresh crankcase oil.

I'm sure someone will chime in with an answer (whether or not its right is up for debate, as long as it sounds plausible.)

Could there be a drain problem not allowing the HPOP resivior return oil to the pan? I don't have first hand knowledge of the inner workings of the HPOP/resivior. Also, the last bit of oil I removed from the resivior had some very small particales in it. Please save the negative/snide remarks, I'm asking for help from my fellow superduty owners not looking for drama. Thanks for any insight.

The res does just what it says. It has to hold enough oil that no matter how much oil the injectors
Are using it retains positive pressure. There is a stand pipe which actually causes the res to never drain. That's what you want other wise you would introduce air into the hpo system and that's bad! I think when the truck is at idle and using very little hp oil the ipr sends the extra oil back into the res. So in theory I think that there could be some oil that doesn't get circulated very quickly but it's not like there is never any fresh oil getting pumped into there. The res has around 35-45 psi in it at anything above idle and when it's cold it can have over 60-70 psi in it. Now when you sucked your res out there is a screen that prevents you from actually getting to the very bottom of the res. All the oil that goes through your lpo pump for the most part has to hi through this screen. Very little unfiltered oil can get into the hpop except when cold starting and even then I don't think it's much. Not sure if this helps, but it makes sense in my head! Just doesn't always get interpreted the same in others!
