So your real question is: will 0-20 hurt my engine? Not will my vehicle benefit by 0-20.
I doubt it will hurt your engine.
Thank you.
Being a Registered Tree-hugger and Greenie, I mustrive for optimal fuel mileage.
Not worried about engine damage - I accelerate gently and on emergencies try to not overly stress the engine going up mountain grades.
Just wondering if Mobil1 High Milage is ideal for a two-year-old engine, or use 0W-16 specified.
Toyota has several vehicles with the exact same engine. The ones built 5+ years ago have a oil viscosity recommendation of 0w-20. Exact same engine built 2 years later and the oil recommendation changed to 0w-16. And now it’s 0w-8. In all probability any of those oil viscosities will be fine.

Which came first. 0W-8 engines or engines which use 0W-8 to gain higher fuel mileage figures?
We all KNOW you’re a troll
We REPEATEDLY tell you to to use the approved fluids, correct procedures, etc.
And you ALWAYS ignore us and do everything incorrectly
You just keep coming back because you’ve got nothing better to do with your life

It is meant for engines with weeping seals, do you leak any oil? If not, 0w-16 is ideal for your car, and will provide slightly better mpgs.

Thicker oil (to a point) is better for piston ring seal, and with your 193K miles it might help it some, all the bearings and such will also have some wear and more clearance (we are talking in the 0.001" range, NOT 0.1") and so the thicker oil can help there also, BUT, it could affect the VVT system… So run the thicker oil and IF it throws a CEL or fuel mileage decreases then you can just change back to the OEM oil… Don’t over think this…
The A25A-FXS engine in your Lexus has used 0W-16 engine oil in the US market since it was introduced in 2019.
That engine was later certified using 0W-8 engine oil for the Toyota Crown.
If you lived outside the United States, you would have more oil viscosity choices.

My wife owns a Crown now. The 2 dealer oil changes done as part of the sale use 0w-8. I use 0w-16 and will do the rest of its life (or mine whichever comes first).
May make sense to use 0W-8 for break-in. Then 0W-16 for regular use until engine attains high mileage.
Though Letsuck says 10k miles, I did first and 2nd oil changes early. Now 7,500 eachange.
I see Troll @Robert-Gift is unwilling to change his ways
You keep referring to Lexus in a disparaging way
Then why the heck don’t you dump that car and get a different brand?
Instead, you’re unhappy with your Lexus and buy yet another one
Clearly, you’re not one who’s capable of learning from his mistakes

Maybe because they specify an oil that is not ideal for engine longevity. Outside the US there aren’t penalties for lowering fuel economy sightly to achieve better longevity.
Wife want Lexæ.
She get new, I get hers.
The RX350h GPS often directs ridiculous routes. (Expecting to see Denver to Moab via Salt Lake City.)
Often directs to take an Interstate exit and then get right back on.
(During emergency transports I have exited and entered to pass hundreds of yards of stopped traffic. But GPS has never directed to do it, then.)
Steering wheel completely blocks turn signals.
Can’t hear turn signals at highway speeds due to wind and road noise. Dealer says only they can adjust the volume. $$?
Lexus advises changing oil 10k intervals.
Other than that, it is fine.
You just confirmed you’re very unhappy with your Lexus
As I was saying
Thank you proving my point

As long as this person has been doing this blood delivery he should not need GPS very often . Plus he can double check with his phone.

What settings are you using in your GPS? 70 goes nowhere near Salt Lake.
I had my GPS set to shortest route , took me down a sand forest service trail.
GPS is used in case of routes blocked by brush fires or accidents.
Cell phone is also compared.
Receiving hospitals are called with GPS ETAs.

Correct.
Some of the routes Lexus GPS has suggested are so ridiculous that Denver - SLC - Moab would not be a surprise.
Lexus GPS directed departing from a straight-through avenue and head 11 blocks north to a busy thoroughfare with many traffic signals.
After a half? mile, head south 11 blocks back to the same 3 [:] through-street.
Was there an accident on the through street? None.
Can a satellite detect a traffic accident? You can display traffic conditions and choose your route accordingly. Traffic condition information is received via the Data Communication Module, not GPS. You need to be in range of cell phone service.
Review your route preferences. Be sure to switch off Predictive Efficient Drive.

Yes, the GPS is set to show traffic problems.
There was no alternate route, so progressed between lanes 1 and 2. Keeps themergencyehicle’s tires out of shoulder debris and drivers do not lose their positions in line. (The returning ambulance should have gotten behind me. On some occasions, drivers have.)
