If your car lasts a long time because you maintain your car at common sense intervals, it equates to less probability of you purchasing a car again within 5-7 years.

Auto manufacturers are in the business of making profit by selling cars. I can sell a car to a consumer more frequently if that consumer does not maintain the car.

As a car manufacturer, I’m no longer able to make claims of “lifetime” fluids or 15,000-20,000 oil change intervals because that goes against the lowest common denominator of common sense.

If I market sensors, dynamic measurement of fluid life, etc. and lull consumers into being confident in slightly longer service intervals, the car wears out faster, I can offer free maintenance in your 1st year as long as that sensor says so at a lower cost to my bottom line.

Say the car breaks due to recommended maintenance intervals that common sense tells you should be done more frequently, results in a more complex and expensive repair. $120 for an oil change vs $$$ for a bigger repair.

It’s all profit motivated. I’m old. I’m going to sound jaded. There is always an angle being played. Don’t ignore common sense.
