Get the cheapest oil that meets spec + genuine toyota filter from dealership online stores and change every 5k. period. so you're good with the Mobil 1 since its cheapest and meets spec. as for filters, for the same price or cheaper, i'd get toyota. if another big brand is cheaper, then sure get that.

don't overthink. you think the fleet mechanics in Dubai are running top shelf expensive oil on their Camry hybrid fleets?

this topic takes up way too much headspace w/ too many men.

Look at the chart below which ranks Toyota OEM filters as the worst of 16 filters tested for filtering particulates (or watch the Brand Ranks video it was extracted from) and tell me you think the OEM is fine. I don't usually overthink oil and filters, but as more test data becomes available, I'll certainly use it to inform my decisions. If I didn't care about taking the best possible care of my $60K investment, I wouldn't be on CL, looking for consensus.

All that said, perhaps Toyota/Lexus engineers want the added wear from particulates to help break-in the pistons, rings and bearings?

My neighbor had a messenger service years ago - Dodge Caravans for years - he changed the oil every 4K miles with SuperTech brand (conventional oil in those days). Ran those vans 300K miles + before he would retire them with engine still running fine.

Don’t compare todays engines with that, especially not the A25A.

I had many Dodge Caravans in my fleet as well. The engines were reliable, but general quality was poor. The mechanics who worked on them seem to like them for some odd reason. The end users--the drivers, not so much!

What if the standard ppm in terms of acceptability is 100, then whether its 16 or 5 or 3 doesn't make a difference. Do we know. or are all these in the excellent zone and just splitting hairs.

what about flow rate, drain back, seal, ability for filter medium to not break down, quality control + consistency, etc. i'd just trust toyota for the filter but by all means use what you want

Most of the top rated filters do everything well, and because they are premium products (sometimes three times the cost of the OEM), they excel in all the other considerations you brought up. I've already ordered my next filter...the top-rated Purolator Boss! And you have my permission to keep using OEM

I don't think these are PPMs, but subjective ranking for each column.

No idea of the source of the chart so I can't speak for the actual findings.

I'm talking about test data here--nothing "subjective" about it. Watch the second YT video in the original post, the source of the chart. The filtering findings are based on PPM. See this chart from the same video:

This explains your indifference to the subject. I was hoping to hear back (and I did) from people who are actively involved in changing their oil. I'm not saying you don't have a right to interject your opinion, you totally do, but since you don't have a dog in the race, I'll take it with a grain of salt.

hybridized a25a is probably the very last engine that needs an oil debate. not some bespoke quad turbo hand built V16 making 1,000hp.

a25a=low strung low hp 4 banger made by the arguably most reliable 4 cylinder engine maker. you can probably mix in some vegetable oil and be alright LOL.

You may be right, and you make some good points, but, why risk a $60K investment over a $15 vs a $5 filter?

That story about the Supra warranty denial is absolulely wild. I've never heard of any such thing with any car brand, let alone Toyota. That dealer and presumably that zone office really shafted that guy.

All motor oil brands have to meet engineering industry standards, which have gotten tougher every few years. The debate over the brand differences in oil filters are legit. But I've never heard of any oil that was the correct weight, changed at the correct intervals, and was nonetheless indicted in an engine failure.

I'm always amused at the endless ability of this topic to agitate an endless debate. Yet I almost never hear a conparably pitched discussion about an engine fluid whose failure is arguably associated with many more catastrophic failures: automatic transmission fluid. Maybe it's because that's changed so much less often that it escapes attention, but I've long found it weird.
