Nope. Experienced mechanics will give you advice & solutions you based on what is visible and not from what is invisible. Visible means leaks. Invisible means nothing worn can be seen now, but is seen later caused by maintenance products such as Seafoam.

Thats the thing. 99% people buys cars and expects the cars to live forever. Why do you think newer cars has lesser and lesser self serviceable parts in it? Some newer cars does not even have a dip stick or even oil filler cap. Everything is passed on to electronic sensors. Also lifetime engine oils. (This exists in USA, but i do not know if any other countries has them yet).

In the end the consumer wants maintenance free cars. Car makers made this their advantage in making the cars buy, use and throw away. Much like Apple products.

To be fair, if your car is only 5-7 years old and you did seafoam or any other type of decarbonizing, cleaning, flushing. That would be fine. Thats the max rate the vehicle life would be at at normal day to day use. But some are being abused. Those are the ones that cause problems.

In fact if a modern engine burns oil (Any engine that uses 0 to 30 grade oil now), you can't go 40 grade or higher like you could with older engines. It would kill the engine cam switching and adjustment features due to the incorrect oil pressure flow needed to make those work.

Whatever the case, everyone should change engine oil at schedule and at least every year, pump a tankful of the the most premium fuel they can buy and do an Italian tune up.
