you would have to change your oil. See the picture below:

Emry, you’re wrong.
So it is fair to say you have come up with your own spreadsheet and formulas and then inserting arbitrary numbers to arrive at 14,775.45 miles?
For instance, how is the MTBF for a liquid like engine oil determined and how did you arrive at 50000 hours? Does that number apply to all kinds of oil like full-synth, blended, mineral equally?

I could also come up with my Excel and put my numbers to arrive at any arbitrary oil change intervals. But then you and the gang immediately question that.

Let's say I put fresh oil and don't drive 14775.45 miles for 5 years because I just commute 3 miles to work every day. Then according to your scientific analysis I should not change the oil for 5 years.

It is true though that you can change full synth oil between 5K and 15K miles but that depends on the driving condition, towing, climate (humidity in the air) to name a few factors.

I change my oil at 5K to protect the engine in the long run. You want to change it at 14,775.45 miles go ahead. So what's the issue here?

Based on my driving condition and climate where I live that suits me. You and others do whatever you think is correct but what is this fuss and childish posts about?

If it makes you happy that I'm wrong and you are right let's go for it.

Not own spreadsheet and formulas. Formulas and equations that are accepted by ASME, ASQ, and other INTERNATIONAL governing engineering bodies. I did not make up the equations. They're accepted all over the world. And the other numbers are engineering estimates for replacement costs of parts, not arbitrary. Arbitrary implies a guess with no logic behind it. The logic behind my numbers are real world estimates based on like and similar components.

Of course we would. You're not an engineer, and you guessed at your oil change interval. I did not.

This issue here is that you're spouting off information to others as if you know everything about this. You guessed at your numbers because that's what marketing people did to you. They got you hook, line, and sinker. You would have made more friends on here had you just said something to the effect of, "These things are what worked for me, they may/may not work for you." But no, you didn't do that, you came on here with a certain cockiness behind your bullshit numbers. That leads to members, like me, calling your ass out.

As far as i'm concerned, you work operating a hot dog cart and the math you do is calculating the minimum amount of weiners you need to sell to pay for a new keyboard every 3 months because you just burn through them at record speed, while you sit on your ass all day "doing math" and trolling on a forum.

Math, haha you probably don't even know how to solve a simple function

Too long; didn't read.

But I saw lots of words, a big spreadsheet, lots of bullet points and numbers. Something tells me it's the equivalent of a mic drop bitch slap, combined.

Last I checked, that's why your owner's manual says X miles, or X months/year. Whichever comes first.

The spreadsheet is geared towards aircraft, not cars. For bitchslap purposes, the units are irrelevent.

Ah, gotcha! I didn't pick up on that conservation of units throughout.

Thanks!

These numbers are universally accepted for engine oil? Give the exact reference (book, website, article etc) so we can check it out.

Well, I was an accident reconstructionist (Northwestern Traffic Institute) for two decades, so your article actually makes quite a bit more sense to me than trying to read "Measurement of Laser-Induced Plasma Properties Using Laser Beam Diffraction".....and I actually did read both of those articles (one of my sons is an Optical Engineer...).

Your points are valid and backed by science, fact, and research. 'Nuff said.

It does not matter if it's oil, a pump, or a piston. And the information is out there, I'm not going to get it for you.

you started the thread with a quest for sharing knowledge supposedly...
but now it's clear you were interested in just being right and having your ego stroked.
In that one long post, Gatr has given you more content to swallow than you know what to do with (and more than I've seen on AZ in months).

EXCEPT for the Tacoma with the 2.7l 4 cylinder(I have one so know about this detail). They keep its interval at 5K. I don't agree/follow this. I do the filter at 5k and the oil at 10k. Full synthetic.

Wait a fuckin second...how do you keep the filter hole from pouring the dirty oil out?
Why not just go for it...for another 25 bucks in oil, have it all changed.

Also, I'm mad that you're a dude. Chick Dr had all sorts of fantasies going through my head.

So that PDF posted by op is some random dudes opinion essay.
I have seen several car owner manuals that are now stating that oils do not need to be changed
but every 7,500 miles or more. The same manual also states OR every 12 months, whichever
occurs first. My feeling is that you can probably go 5,000 miles on the average (in a sports car)
but you must change your oil in the spring time at a minimum, particularly up north. Oils form
waxes in icy cold weather. There is a permanent thickening of the oil.
Another one
I firmly believe this based on all I know about oils.
Much english, very run on.
Since the synthetic oil thickens less on shutdown your startup will be easier and so will the stress on your engine.
There's even a gawyammed test at the end of the gawyammed pdf.
