"Break in" mileage
Have a new 2023 RX 350. Dealership said we should "go easy on it" till x mileage but I forget what it was, and Id like opinions here anyway.
Currently at about 2k on the odo. How much should we put on it before we can "floor it" or is that just a myth?
Thanks!

Today’s engines do not really require a break in period. Most manufactures say not to tow anything for the first thousand miles. I tend to drive pretty easy for the first 1000 miles but that is just me. Some say drive it off the lot like you stole it. The choice is yours!
At 2K, you are safe to floor it! Enjoy!

From page 174 of the RX Owner’s Manual:
A quick search of the PDF version is all it takes to come up with answers like this, quicker than posting on a forum.

Having said that, I did want to hear what others had to say.
Thanks everyone!

‘’When and how often to change oil will create lots of opinions, just make sure you change at least as often as what Lexus requires, doing it much quicker is just a waste of resources and money.

It is old reasoning but their preference. At near 1300 miles my oil is still so clear and clean it is difficult to see on the oil stick. They want you to change per the Maint schedule which I believe is at 10K. I am a little old fashioned and will likely do my 10K at 8K miles but that is my preference.

Does anyone here know of anyone who has even heard of a Lexus engine problem by only doing the bare minimum required maintenance? Unlikely. Read the manual, do what it commands and drive on.

Interesting. I've never done it before, but I think I will have the oil and filter changed at 1000 miles.

This is an old-school thing that I've followed on every new car I've had. Some argue it isn't necessary but the cost of one oil change is very cheap insurance.
Why?
Engines have tight tolerances. When new, the metal parts within the engine have a lot of friction. In spite of the lubricating oil, metal is ground out and shaved. Much of it is near microscopic. It's the job of the oil filter to remove these metal particles from the oil. Most of this initial wear occurs within the first 1K miles. So, the old-school thinking is to perform a change of oil and filter (especially the filter) to get the ground up metal out of the engine. Yes, the oil is designed to hold particles in suspension but can it hold them for the 10K miles? Depends how much there is.
Oil drain plugs are often magnetic. That is to trap the metal shavings that don't get filtered and can be removed at the next oil change. If you are there to see it, check out a drain plug at an oil change. It may look like the photo below. You can also open up the replaced oil filter and find metal shavings.

That's not my photo. I just picked it to demonstrate the metal on the plug.
