Full synthetic vs. conventional 500K miles side-by-side teardown

[BillsCamino]

I go by the onboard Oil Life monitor to trigger an oil change . Older vehicles I change oil every 5K miles
Both my Fords recommend a synthetic blend

I'm sure. It was interesting though. My best friend growing up was a mechanic so I'm up on maintenance. I have to say I don't have to spend much on repairs so far. I used to spend about $1500 on parts, maintenance and repairs about every 100k miles. That's tires and everything as I recall. I don't keep up with it like I used to, money wise that is. I just don't worry too much about it. Do my maintenance and drive. Fix somethin if it needs it and keep going. Even my Dad is like buy your wife a new car....Why?? She's happy and purrs like a kitten. Goin on 400k......I'm still driving 40yr old cars....I know her's won't last forever, but I already have somethin else for her to drive when the time comes. It's not the engine that's goin, it's the original automatic transmission.....

My 2019 Ranger with 2.3L Ecoboost (same engine as in video) doesn't use a drop of oil between changes. Granted it only has 22K on it

Most of the wear on an engine is from starting. If someone sold a pre- lube system for a passenger vehicle you would be surprised how long the engine would last. Turbo's like clean oil so I don't understand why the 10,000 oil change , if it was my vehicle I would change it at around 5000 mi. And 3500 as the milage increased.

I cannot understand the latest Auto Stop/Start feature on recent models.

Shutting the engine off while not moving stops oil flow to hot turbos.
Crazy !!

That was the first thing I disabled. On Fords it takes about two minutes to do.

Studies show that the biggest cause of engine wear on fuel injected engines is fuel dilution of the oil, caused by dirty injectors not getting a good atomizing spray pattern. If the injectors get dirty and they don't spray like they should you end up with unburned fuel washing past the rings and diluting the oil. I agree with more frequent oil change but even more important is to run a good fuel system cleaner through your gas tank at least as often as you change the oil if not more often.

If it's got a turbo its going to use some ol between chnages. Whether its brand new or has 300K miles on it. A turbo burns some oil no matter what.

I agree! New 2020 3.0 used 1 qt. In between!
