Oil Change Advice

[TimC.]

Alright my last ditch effort here. Your 4th gen has a turbo. This will likely be the fist failure over time. For all doing the 10k oil changes please post your engine health status as you get to high miles. I would love to be wrong.

What's not usually "discussed" and the point of the OP's video posting (for those who are not watching it - likely most) is the Car Care Nut emphatically says change oil on turbos not every 5,000 (vs laughable 10,000 - Oil Geek Guy has video explaining why Toyota does this. It's not about Joe Consumer - sorta) but every 3,000 miles. "Back to old school" to quote the CCN.

Toyota: "We've spend billions of dollars and years of development and testing on our engines for durability and performance".

Some guy on the internet: "Bullshit!"

Perhaps the guy on the internet could helped Toyota solve the Trundra engine recall? Must have only spent millions on that engine program. Billions, yeah billions would have prevented that failure.

The other guy on the internet is only a NASCAR tribologist that developed the lubrication program for Joe Gibbs racing, won 2 NASCAR championships and the major developer of Driven Racing oils additive package. Yeah, just a guy on the internet.

I can't find the specific video of Motor Oil Geek guy, but you are swallowing that the engineers/Toyota corp only have the regular consumer in mind. It ain't that simple - hardly - the 10,000 mile stuff is Toyota corp demanding this type of stuff for many things, besides us, including fleet and rental operations - which are HUGE part of their business. Huge.
So, as MOG goes into great detail about - the engineers are made to serve things very different from our needs as Joe Consumer. It was eye opening and explained this bullsh*t yes, bullsh*t about 10,000 mile old changes. Care Care Nut is totally against it as an example (he serves the consumer - not fleets or Hertz) - I rest my case.

I'd also add in that any manufacturers testing for real world wear and tear is inherently flawed. While yes, they can use run stands to simulate operation and test mules for some real world testing, they can't simulate thousands of real world cold starts at wildly swinging temperatures (midwest) and varying driving habits of millions of their customers over hundreds of thousands of miles. Any recommendation is going to be based on lab generated results, math, and a generalization that's going to attempt to cover everyone's conditions based on their own company philosophies and culture.

Prime example, if you open the manual of most German auto makers and turn to the oil viscosity recommendations it's going to show wildly varying tables based on narrow operation temperatures rather than just a single option which frankly confuses the hell out of many of their customers.

Another point, most engineers are taught in schools without much real world basis to their education. Many are not even mechanically inclined. They are also not given the entirety of the information required for their design. Manufacturers may take a engineered part and use it for an entirely different purpose vehicle than it was designed for.

I work in manufacturing, I can tell you first hand as someone who sometimes has to implement an engineers design, they are more often than not flawed. Sometimes critically to the point it cannot be implemented. But that's not always their fault because they are sometimes given incorrect specifications and are working from an office where they never even see the equipment they are working on, and just using prints.
