Top end oil change ?

[f250power]

Has anybody tried the top end oil change yet ?I tried it today, well I started it but rain stopped me. I was going to just keep taking out and putting in until I used the whole gallon of oil. I was a little concerned though, in total i pulled out 1.5 quarts but ended up putting 2 in. I checked my dipstick both at the beginning and the end, same. didn't bother to check the level in the top before, made sure it was filled in the end though. Anybody had this experience, think I might have been low in the top. Also oil smelt burnt, my dipstick oil smells brand new.

Never even heard of this. What is exactly involved. Being the truck holds 15 quarts of oil. You used a gallon of oil but you only pulled out 1.5 quarts and ended up putting in 2 quarts. This all doesn't make sense to me at all.

The guy has a pretty good idea...There's 3 quarts of oil we're not changing when we do maintenance... I'm not sure it's worth the hassle, but he has logical reasoning behind doing it

would this actually help any or is it just bs???

Never heard of that before, but he makes it look real good.

I just changed my oil about 400 miles ago. I have a vacuum pump and a isolation bottle already built for my hvac work. This weekend I will pull out the oil from the reservoir on top and compare it too the oil from my engine pan. I will try to post pics from my results.

yeah i watched that video the other day. never knew i had to do that. has anyone done this before as a routine maintenance? maybe a tech on here will know if this is important?

I would argue that the 3 quarts does get changed. He stated in the first video it does mix in with the regular engine oil. So it maybe every other oil change but that oil still gets changed.

Remember that the low end oil supplies the hpop with oil on these engines. Also to make this affective you would have to do this at the same time you change the low end oil.

I think the he is probaly right. With your logic Big it would be the same as changing your oil and then topping off with 3 quarts of used oil. Because just draining the oil does not clear the upper. It would take several oil changes to clear the upper and you would still have old oil in the upper. I'm not trying to argue, I'm saying it seems it would be the best idea to change the upper and lower at the same time every time.
