I have in the past done a lot of testing when I got my first 99. Reg old Rotillia was still good at 6,000 so that is what I went to for change interval. Then we took the truck to Italy and oil was very expensive. So I did the AMSOIL single bypass and went extended drain. I would usually run it 20,000-30,000 miles with no problems only reason I changed was usually I had valve cover/turbo off for one upgrade or another so just figured I would change in case some crap got in the oil. If you are going to change at say 25,000 I would only test it through the first run. Once you know it will go that long, just do one test at the final drain or not at all. Most people don't test the oil when doing 5-10 grand changes and never think twice about it. I usually put less than 10,000 miles on my trucks now so I only change once a year. Time is money so if you put a lot of miles on your truck in one year 50,000 eliminating 4 oil changes will pay for itself in both supplies and labor. No right or wrong just things to think about.

Amsoil with filter $175 plus $35 OA = $210 every 25,000 miles

Motorcraft with filter $160 every plus #35 OA = $195 every 7500 Miles

I only tested frequently until my baseline was established, according to Amsoil OA I can extend the service interval if wanted but would have to add another $30 for new filter and $12 for the extra quart of oil.

Correct, I only test at time of oil change. The frequent changes in beginning were to establish a baseline where I would determine change intervals. I am turning about 50,000 miles annually, lots of driving.

That must be that new Common Core Math. LOL

Not sure how you get to $160 or why you want to add the $35 OA (not really required for 7500 mile changes) to the cost but hey...you do you.

Do you honestly go 25k without any additional oil added or filter changes?? What flavor of Amzoil are you using??

I would change my main filter at 10-12 grand and Bypass at 25 grand. Makeup oil was as usual, fresh oil was good for about 5 grand than used a Qt every 2 grand give or take how hard it is working. Oil usage is about the same with or without bypass once you have 4-5 grand on the oil.

Damn dude, you gotta get the last word in dont you ?


https://www.oreillyauto.com/detail/b...il+5w-40&pos=8

^^^^^^^^^^^^^^^^^^^^^^^^^^

x 3 = $120 You Follow me so far ?

https://www.oreillyauto.com/detail/b...l+filter&pos=7

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^

$120 + $20= $140

$140 + $35 OA because Its my truck, I pay the note and can do whatever the F&@K I want and I want to know how my motor is wearing. I call it simple addition and multiplication , no calculator required.

I trust Amsoil in their claims that the oil can go extended intervals, I trust the engineering that says the filter can go what it does and I trust Blackstone Labs telling me oil can go further, I just choose to change it at 25K versus pushing it further. These are both ISO companies who spend millions of $ in research to provide the info they do. You show me something factual that you have and I will believe it but just because you say and are a keyboard warrior doesn't hold a damn drop of water to what I have.

I asked a simple question about what could be causing high silicone levels and you have derailed the post into criticizing my routine maintenance schedule. Thanks to those who provided help and I dont have a problem answer questions for other forum members but damn dude you come off as a dick

Yes I do go 25K without any additional oil, I use a filter that's rated for that mileage and the truck doesn't burn a drop of oil and I check weekly(roughly 1000 miles) Do you have secret intel that says I should add when not consuming or losing oil ? My truck will be 2 years old in 4 weeks, I have 95,000 miles where all Ive done is change the oil, trans fluid 30K,60K,90K, Transfilter, fuel filters and air filter and its never been into Ford House for a thing. Its the best diesel I have owned I doubt I will have it another year but I am about to delete it just to increase fuel economy. The truck has made me 10s of 1000s of $$$ by moving a 12,000# piece of machinery between sites in Texas as well as moved over 1,000,000 #s of Quartz and Granite between Dallas, Austin and San Antonio. When loaded with Stone or machinery, Im right under the 25,999#s before I need a CDL or DOT.

Okay...all you had to say was..."I want to spend the most money on oil I possibly can cause I want to."

That's really all you had to say.

Enjoy the 25k intervals.

How much fuel is in the oil at 25K miles?
Silica also comes from pavement dust (sand dust).
What air filter are you using?

Frank,

< 0.5 Fuel, I use Ford Filters. Silica is introduced via the intake system but comes from many different orgins.

Thanks

Thread now painfully long to read through.

High Silica in UOA.

Out of curiosity, do you run Blackstone tests at 10,000 miles?

What are the silica levels?

I don’t know what the silica should be at 25K miles because very few people run 25K mile OCI.

Many people run 10K mile OCI and so there is a good baseline average established.

My own opinion is you need a dual filter bypass filter like I said in my first post.

It is very impressive that you have worked that engine so hard and it does not burn a quart of oil in 25K miles.

All OA results are in the attached OA on page 1.

It doesn't burn a drop, Im very impressed and to say Ford did a great job is a understatement. I do some hauling but Im guessing that only around 20% has anything more than a 1000# Jetski and trailer behind it.

I make a 500 mile round trip at least once a week, daily commute is at least 150 miles and on weekend the truck has more room for wife a kids. This truck doesn't get any rest, very impressed with everything about it.

Thank you for your comments
