Res oil change question

[Brickhouse]

Here’s a discussion a few of us here are into, and I can’t find an answer in the books and disks I have. For oil changes, I’ve always also did the reservoir. Question, is there a Ford TSB or other official Ford instruction to do this? It makes since to do to me? Why leave that much bad oil in the system. Anything out there?

it is not necessary at all to do. I have an oil sucker, so i do it when I cahnge my oil as well. But there really is no need, and there is no evidence that it makes your injectors or engine last longer at all. There is still quite a bit of oil left in the rails in the head, etc. Theres i beleive two quarts betwwen the rails, lines, res, etc. so you're def not going to get it all anyway. So no, there is no need, and shows no benifits. But, i do it cuz it makes me feel better

how do you change the reservoir? what is the reservoir?

Not Again!!!!!!!!! Listen I have worked on plenty of 7.3's with well over 500K and a few over 800K and not one of them has ever had this done and all are still on original blocks and never been opened. This wasn't even heard of until that dude posted it on You Tube. I listened to one of his vids and he actually recommended the K&N filter, shut him off and will never listen to his BS again. If it makes you feel good do it, but there isn't any benifit to it. And if say your truck runs better afterwards, PLACEBO!!!!

I don't really like that guy either but.....whats wrong with using the K&N in an early 99 7.3? My truck seems to run way better and get better mileage. I am not trying to be smart....I just don't know the downsides. What are you saying is the downsides to a K&N in a 7.3???

K&N gets its higher airflow by less filtration. That means more dust is getting in your engine. And i can only hope you know what that does.

[Brickhouse]

Thanks everyone. Cleared up the local discussion. That was exactly the answer.

Have a great holiday season.

[robthebuilder]

Yeah, it's pretty much common knowledge among diesel guys that K & N is a no-no.

Every filtration test I have ever seen always places K&N dead last!!!! Even pantyhose filter better than a K&N!!!!

Is that a serious comment or just a joke? If serious, that's pretty bad... but is funny.
