Camry specs?
Let's see.
For the typical Camry owner, it's as follows:
1. Drive car until little lighty thing comes on.
2. Add fuel, which makes little lighty thing go off.
3. If car deserves a treat, consider an oil change.
That's about the amount of expertise the average Toyota owner brings to the table and is the reason that Toyota offers a period of free maintenance on new cars.
Having sold its cars as being maintenance free for many years, Toyota now has to deal with the inevitable backlash.
I base this upon those Camry owners I know and have known.
They're not usually car people, but rather people who use cars with no understanding of their functional requirements.
They often avoid paying for all of that overpriced nonsense that the OM recommends. After all, they didn't do the last scheduled maintenance and everything works fine.
Why pay for an expensive oil change using the recommended 0W-20 synthetic when the engine runs just fine on the oil from whatever was used the last time it was changed for twenty bucks, which would have been the last time the car deserved a treat?
We're looking at a group of owners who couldn't even figure out how to position the floor mats in some tragic cases.
Your post serves to illustrate this, selective quotes and all.
You seem to take issue with the notion that Toyota's oil recommendations should be followed and call this "internet arrogance".
Really?
