At how many miles should I bring in my 2019 RX 350 for its first oil change/maintenance?

 

Welcome to the forum. I think you would be better off posting this in the appropriate RX forum - this forum here is not a model-specific forum so you may not get many responses as the RX owners may be hanging out in the dedicated RX forums. Also, your owner manual and/or paperwork from the dealership should spell out very clearly all of your maintenance intervals. Good luck!

 

Lexus recommends first service at 5k, and second at 10k. The 5k service is just inspections, tire rotations, etc. The 10k service includes the first oil change.

 

Welcome to CL.

Traditionally, the first oil change is usually the most important one for the life of the engine. Although new engines, today, are built to much closer tolerances than in the past (requiring less break-in), and much better oils/oil-additives are used, still, the first change (with the filter) is important to get out any shavings and other impurities which wear off during the shortened break-in process. I'd do the first change within a few thousand miles....then let the oil-use computer or maintenance-schedule determine the intervals after that.

 

I do my 1st change at 4,000 miles with Castrol synthetic.

 

What does the service schedule say in your manual, or on line for your vehicle? ¯\_(ツ)_/¯

 

It is different for most vehicles, so please consult your owner's manual. It's also online at Lexus.com, under "owners."

 

I do all my own oil changes at 10000 miles. The first however I do at 5000 miles. It might be overkill but it cost me about fifty bucks. I buy my Mobil 1 oil and Toyota oil filter bought online and take it to my Lexus or Toyota dealership who charges me $30 in labor

 

Thought I'd bring a little humorous closure to this thread....

First, as I mentioned earlier in the thread, I was able to confirm on the Lexus website that the service on the vehicle had been done IAW proper schedules. So, after that, I got off work yesterday and went to actually drive the thing. And it was everything you would expect; nearly flawless shape, more responsive than I expected, and when I did an OBD scan the thing came out perfect with no fault codes in the last 28K miles.

So I was ready to sent them an offer on it today.....figuring it was close to the end of the month and they'd already had it sixty days, thought I'd have a chance to swing a sweet deal...only to find out it had been sold this morning (Or perhaps they gave up and sent it to the auction? Who knows.)

Oh well, sometimes you win some, sometimes you lose. There will be other vehicles.

Thanks for all the input.

 

Did you mean to reply to a different thread?

 

Wanted to revive this old thread with a new twist regarding the first oil change...

In the old days, some people would perform the first change extra-early, due to the likely chance of extra wear particles/metal shavings common in new engines. Many early autos didn't have oil filters, including my beloved air-cooled VW's. As mentioned above, manufacturing progressed, building/machining tolerances got better, oils got better and wear-in (break-in) times became shorter. That said, along the way, some manufacturers used specially-formulated oil additives to help engines wear-in better.

I have no information regarding which manufacturers used which wear-in additives, for which models or for which years of manufacturing. However, I do now pause to consider this history when faced with the first oil change interval on my new vehicles. I want to believe the sooner, the better, but I'm not certain if wear-in additives are still a thing and if it would be advantageous to leave the original oil in the full interval. Any thoughts on this CL?
