oil change interval
OCI is 10k miles on the lexus 2.4L turbo. OCI is 5k on the toyota 2.4L turbo as far as I can tell. are people trusting the 10k OCIs even with a relatively small oil capacity of 5.6 quarts or so? I am coming from german with 10k OCIs where I changed it every 5k anyways.
I was thinking 7500 miles but would like to know other's experiences with lexus and OCIs and longevity. and I know oil changes are a lot cheaper than new engines...

I too have a long history in German cars, so I hear you...
Also I'm an occasional reader on the oil forum "Bobistheoilguy", having said this I'd go with earlier (you pick the mileage) oil changes. I used to believe that a ~10K mile oil change was acceptable, but I've come to the realization that the oil ring on a lot of these motors has difficulty when extended oil changes are implemented. Simply stated, motor failure rates due to a gunked up oil ring are higher.

Yup totally get it. I am contemplating going with 7500.
minor maintenance from factory is on the 10s and the majors are on the 20s and 30s.
the only red flag I see so far is no diff or
trans fluid interval. Also brake fluid every 36k/36mo seems suspect and I would rather do every 24k/24mo.

Not saying the 10k recommendation from Lexus is wrong. But $100 every 5k miles is cheaper than a new engine. Especially a DI & turbo engine. Just my opinion.
My GX calls for 10k, and I do every 5k. The RCF calls for 5k.

I would suggest 5K with full synthetic oil too.TX has the turbo, which require proper oil lubrications. A dirtier oil might have too much metal debris that clog the turbo.

I would do 5k OCI if you plan on keeping the vehicle for a long time. Would also buy better oil like Mobil 1 EP or Pennzoil Ultra Platinum and change it myself or bring it to an independent shop.
Not sure what dealer you use in MA ( I go to Herb Chambers of Sharon or Northborough), both are good locations.

nothing will "clog the turbo" I have sold a lot of turbos in my day and also had a lot of turbocharged cars. what I do know is dirtier oil can easily cause unnecessary wear on the turbocharger's bearing. I am unaware if the bearing is a journal or ball based. either way a cleaner higher quality oil will help prolong the lifespan of the bearing in the turbo...

I am also contemplating as long as I am living in Woburn, trying to take it to the Toyota dealer because if they can change the oil in a grand highlander they can do it in a lexus TX...

I'm going to stick to the old tride and true: AMSOIL full synthetic every 10k. Can't go wrong. As the vehicle ages and gets to ~150k miles ill go every 5-7k miles. Stick with Amsoil and do the oil change yourself and you be just fine.

Amsoil makes a great product. there are many good oils out there on the market and Amsoil has a lot of respect especially in the high performance market.

If you want to nerd out and you do your own oil changes, get a few of these kits and you can dial it in: https://www.blackstone-labs.com/
Send in your break in oil at 3-5k, then do another at 5k and see what it looks like; they'll give you some narrative notes as well. Chances are 5k will be clean and stable, then you can do 7.5 or 10k and see the difference and pick your best number. Then do it every 20 or 30k to see if anything changes against the base line and adjust as it ages.
Or do it every 5k and and you'll be for-sure fine. It is interesting to have the data, though!
