Isn't 10,000 miles kind of long for 1st oil change
I just bought a 2015 RX 350, reading through the manual it shows a 5000 mile check up and no oil change till 10,000 miles. I have rebuilt engines and you always have small metal particles from the break in, there is the friction from the rings seating to the cylinders etc. I don't understand the logic with Lexus on this. The oil in a new engine will get dirty quicker because of internal mating of metal surfaces. I know the filter will collect these particles, but the oil still gets dirty looking. I may be over doing it but I'm going to change my oil and filter at 3000 miles for the first oil change.

Don't do it, garygve. Lexus changed over to synthetic back in February 2010 and bumped up the oil change to every 10K. There haven't been any problems since. Now a few members have had their used oil analyzed. The results were unremarkable, meaning the oil worked just fine. Maybe you want to change the oil at 5K to get out any particles but 3K is a waste. I know it's hard to get beyond the old school mentality but you'll be fine waiting until 10K. And don't forget, your first two services, the 5K and 10K, are free. Save your money.

I personally do it every 5k with 0w-20.

When I was in engineering school (mechanical) we were taught that current manufacturing processes do not leave behind the kinds of metal shavings we previously dealt with in new engines. The ability to better control the tolerances, forging, and machining processes have come a long way. This is the reason why break in periods have changed, as have oil change frequencies.
With that said, it is very challenging to leave behind my long indoctrinated beliefs that oil should be changed every 3k miles. I do now, however, just follow the manufacturer's schedule and haven't had any issues.

Anita, as you know, I've been getting about every other oil change analyzed at BlackRock. I think I'm done with that now as every one has been just fine as well. To the OP, starting with the 2010 models, the RX and most of the Lexus fleet went to the new low friction engines w/precision tolerances and using 0w20w and 10K changes for normal service. When I had my 1st oil change I had it tested and there were no excessive metal particles. You should be good to go.

Thanks Jim. When I was talking about old school, I was referring to the 'changing the oil every 3K religiously' mentality. I did it myself for many years, that's why I remember it so well. But then I bought my first RX in 1998. Prior to February 2010, the maintenance schedule was every 5K/6 months, whichever came first, as far back as I remember. After the change to synthetic, I waited a year to have the oil changed on the 450h for the first time. Felt weird but all was fine.
BTW, I found this thread pretty much asking the same question in regards to a 2014 RX.

There's been a great deal of discussion here about oil change intervals, 3K,5K,10K. Well, here's another thing to throw into the mix. My friend just bought a new CRV and there's NO oil change interval printed in the service booklet. Turns out the computer tells you what percentage of oil use is left remaining on your oil, then you get an oil change is iminent warning on the dash which changes to change your oil now, when it's time. Holy cow!

I'm not sure about Toyota/Lexus but other makes such as Honda and Subaru on certain models are known to have special "break-in" oil by the factory that has certain protective additive packs. Changing oil too early would negate activation of these additives.
I would be curious to see if anyone has sent a sample of their original fill oil to analysis to confirm if any known additive packs have been detected.
