Sounds like he could just add oil without ever changing it and just swap the filter out occasionally.
If he were to pull into a full service gas station he could say " fill the oil and check the gas"
Here's a 25¢ question. Friends $300 car with >300,000 miles. Uses & loses a qt of oil every thousand for many years. He changes the syn. oil & filter every 5000 miles and filters the drain oil. The filtered drain oil is used whenever the engine needs a qt. When the drain oil is all used up he changes the oil and filter. In one point of view the oil is changed every 5000 miles. In another point of view the oil is never changed.

Let the first oil from Toyota breaking in the piston rings guys for the first 5k miles. Then after that you can do 1k Mile oil change or 10k mile oil change is all ok. Just top the oil level all the time. I like Mobile one at Walmart.
If you worry about the metal flakes, then just change the filter at 1k, 3k then lof at 5k. That way the piston rings have a chance to break in and seat nicely on the cylinder wall.

One thing i do not like about the design on the 2.5 hybrid engine is the way the oil pan drains on the side of the pan instead of directly below. This means heavier particles like metal bits end up still in the oil pan even if you do an oil change at 500 or 5000 miles. The best is to remove the oil pan or somehow find a way to suck the remaining oil from the oil pan. I am certain doing a standard oil change will still leave more than 50% of metal shavings inside the engine.

In my subaru FA24 engine i can remove the dipstick and suck the oil using a Mityvac fluid extractor. I wish i can do the same for the Toyota hybrid engine. Let me know if there is a similar way to do it for our Sienna.

I'm not sure what would be stopping you from using a fluid extractor via the dipstick tube on the Sienna the same as your Subaru. At 5k, I did exactly that (I had changed the oil and filter at 1k with the traditional method and then did only the oil at 5k and left the filter (M1)).

I didn't think of this when I got the 2014 Sienna (new), but my '16 Miata does not call for an early oil change. Of course, the Miata enthusiasts on the Miata Forum are all over the map. They love the car so much that they will do anything to "preserve" it. Mine was on the lot for 18 months before I bought it with 428 miles, so I decided to do the first change at 3000 miles due to age. I am sure with the Sienna we went with the mfr recommendations. My understanding is that engines do not use a "break-in" oil like they used to many years ago. My Sienna uses virtually no oil between 5k changes. Since I prefer to drive the Miata, the Sienna is lucky to get 5k in a year.

Yeah, it's been discussed alot and I think the consensus is the early oil changes on modern cars isn't needed. We have a Sienna that was a rental van. I am 99.9% sure there was no 500 mile oil change. We currently have 210K miles and it's still going strong.

I bought a new 2002 Sienna shortly after nine-one-one when sales were zeroed out. I also changed oil at around 1000 miles, the Toyota guy made a face which if I had made at him, he probably would have slapped my mouth. In 2017, I donated that 222,000 mile car to a Bible institute since I lived in Mexico and with permanent residence had to have a Mexican car. It started and ran like a new car. Mostly, it was driven on the open highway. I had a Blackstone oil test done once at 8500 miles and the lab said the oil was good for another 3,000 or more miles. So, after that I changed it at around, ahem, 8500 miles. When the warranty is in effect, change per manufacturer's rules, of course.

Toyota Care's first free change is at 10,000 miles. In my opinion this is way too long. I paid to have mine changed at 5,000. I think it definitely needs the initial oil change way before 10,000 miles.
Yeah - i would agree with you - 5000k miles should be the first oil change. There is just too much wear/tear after the first few thousand miles after these engines are built. All that metal has to go somewhere. I have seen firsthand what a 800 mile engine's oil looks like. I have to admit - it was not on the A25 toyota engine but the FA24 engine. There were metal shavings that never ended up in the oil filter. If i did not drop the pan - i wouldn't have seen it. Nobody can convince me under normal use - the 0-10,000 mile wear is the same as the 20,000-30,000 wear. No way they are equal.

Oil threads are always fun....
Indeed. I feel so sorry about the poor dEVils, who, in absence of the evergreen "oil change subject" had to invent their own, the now-famous "Shall I charge my ___ to 85% or 90% to prolong the battery life".

Two other fun discussions to jump into are the "AWD vs Winter Tires" and the "Donut vs. Full-size Spare Tire vs. Tire repair kit".

I think we can wrap this topic up…
It will be personal reference whether to change the oil early or wait until Toyota recommended interval..
If you’re a car care enthusiast, change oil at 5k miles so you have something to do..😁😁😁😁 Otherwise, drop it off at 10k miles and let the dealer takes care of it….👍

If you do your oil change - do this. Attach a poweful magnet just beneath the drain plug of your vehicle. Run the engine a few miles (to circulate the engine oil and warm it up) - longer the better. Drain the oil to a trickle. On sienna's the drain is on the side - so a lot of oil still remains inside the pan. If you can - try to put your finger inside the hole and see if you can feel any metals attracted to the magnet (near the hole). In my case it was very small (like glitter) but you should be able to feel it with your fingers. Tip: Tilting the van to one side (using jack) helps drain more oil too.

If you are questing oil changes go watch The Car Care Nut on YouTube. He has a lot of good information. What dose it hurt to change your oil a little more often if it mean it could extend the life of your investment. BUT, make sure you go to a shop that is really changing your oil, I have had them just try and change the filter and said that was good. Make them do a full oil change.
