Good catch, and sorry I missed this! I used the dealer oil for about 1,000 miles. At 10,985 total miles on the engine I drained the dealer oil and went back to Pennzoil Ultra Platinum 5W-30. So from 10,985-15,311 miles equals 4,326 miles on the Pennzoil Ultra Platinum.

As the owner of a '23 RX350 with this engine, I will chime in on this one. Good to see some discussion on this engine since it's use has expanded across the Toyota/Lexus line. As far as I can tell, the owner's manual excerpt that @JavierH19 posted is from the Australian market manual. The only...

I thought that I would share my first UOA on this engine (T24A-FTS) for those here that might be interested. Oil tested was Pennzoil Ultra Platium 5w30; 4,326 miles on the oil (mainly short trip/spirited driving); 15,311 total miles on the engine. I was specifically curious to know if this...

Nice to see some new life to this thread. I think that Toyota/Lexus models will likely be using this engine for at least a few more years across their product line, so it would be beneficial to identify some good oil alternatives to what the US owner's manual recommends. @SimpleSyrup: spot on...

Sorry Pablo, and with all due respect, but in my experience using this oil in my 6.4 Hemi it sheered a A LOT in only 3,500 miles. It went from 14.8 cst @ 100*C (VOI) to 11.76 (my own UOA). I do work the engine hard (severe duty, IMO) but I expected this oil to perform much better than it did...

VERY well put. JMHO

I posted this in the VOA Database thread and it was suggested that I post this VOA in a stand alone thread as well. So here it is.

Good advice; I'll get right on it.

VOA for HPL Premium + 5W-40.

I hope that I am not the only one that gets this........ It does go back a ways.

I have a 23 Lexus RX350 with the same engine, bought new. I changed the original oil at 1,000 miles using Mobil 1 0W-20 and changed it again at 5,000 miles with Pennzoil Ultra Platium 5w30. I am not concerned about a warrantee issue using a heavier weight oil for a few reasons, the main one...

Yeah they now have the T24A-FTS engine in the RX's. As this engine is still relatively new and long term reliability is yet to be determined, I look forward to the OP's future used oil analysis.

I know that the OP has not responded to your question so I thought that I would chime in. I have a 2023 RX350 which has the same body style, drivetrain etc. I am REALLY impressed with this vehicle. Very smooth, quiet, and despite it's not so big 4 cylinder engine, it has plenty of power when...

Good grief people! The OP started a thread to document his/her test and experiment with Valvoline Restore and Protect. I really don't think he/she was asking the community "which oil cleans the best". Perhaps the "which oil cleans the best" question should be its own stand alone thread. And...

Thank you very much for taking the time to share this information. I have been lurking around here for quite some time but finally joined so that I could post on your thread. I have a 23 RX350 with the same engine. In case you haven't seen this, here is some good information on the engine: T4...
