Peruse the motor oil aisle at your friendly local Wally-World.

They are now marketing older, out-of-date API spec motor oil for "older"
cars.

This is NOT like the Pennzoil or Valvoline that is marketed as having been
designed with additive packages for older cars.

This stuff is, simply, out-of-date, non-current API spec oil.......

Well, its actually an all-makes forum as well. Look where its being posted.

Which are snake-oil anyway...

Which can actually make the oil better for certain applications, so long
as it was a decent oil to start with (though most of the ones you're
describing aren't). The current API specs require lower percentages of
certain additives, particularly ZDDP, which are critical for engines
with high-pressure sliding contact points- things like non-roller cam
followers and gear drives of various types.

That's why a lot of us with vintage cars have switched over to using
diesel-spec oils (Shell Rotella, Mobil Delvac, Chevron Delo 400, etc.)
instead of the latest "greatest" API spec'd gasoline engine oils. Even
the diesel oils are having their percentages reduced, but not as quickly
as the gasoline-engine spec oils.

If you want lots of ZDDP, you might want to try the RLI Bio-Syn oils
(RenewableLube.com).

IIRC, their oil has about 2,000 PPM (parts per million) of phosphorous
and zinc (engine wear protectant additives). Can't say for sure if this
much would eventually harm your catalytic system.

The OP asked about a specific Toyota model.

No, it is not an all makes forum. People post about politics also, but that
does not make this a political forum.

rec.autos.tech does seem to be flooded with huge quantities of Toyota
problem posts lately. Which is hilarious, because I always heard that
those things "never broke down." :-p

Yes, it is. I was referring to rec.autos.tech... which is definitely
about all manufacturers. I don't read alt.autos.toyota except for all
the cross-posting that goes on. And when I reply, I try to keep it
general if its also going back to .tech as well.

If 0.1% of the Toyotae break down each year, then that is around maybe
25,000 a year.

Toytota sells more cars around the world than anyone else.
