Does My Car Need ZDDP Additive??

Filters today are criminally undersized and at the heart of many engine woes.
Many are too small to even be an effective fuel filter!
The one on my old ECHO is tiny, in fact it's the same size as the one on my standby generator. Yet I've gotten nearly 300,000 miles on the little 1NZ-FE engine. My even older Sienna with the "sludge monster" 1MZ-FE has only a slightly larger filter and I've gone almost 450,000 miles on that one. Since the filters are "criminally undersized" should I sue Toyota?

No but I should have - and I've proven that the Genuine Toyota Filter was to blame.
I got a bad batch and you got a good batch.
Lucky you unlucky me - and my wife's car too.
The sample size is much larger than your isolated experience.
