Oh you can get by with 10k. But for people who want even better results, 5k is optimal. You can floss your teeth every other day and you'll be fine. but every day is better! Again, we're talking specifically hybrids here. Though i wouldn't be against doing 5k-7,500 changes on an ES350.

 

Why not do it at 1K to be super safe the way the old belief was. The very first second the engine is cranked it starts to deteriorate. The engine should last the life of the car doing what is recommended and only changing earlier for adverse conditions. This is totally personal preference and who you believe in your decision.

 

I would agree with you if you would just say "on YouTube" instead of "in the world". Have you found the Toyota mechanic called "Toyota Maintenance" on YouTube? He might even be more OCD than Ahmed the Iraqi. The Toyota Maintenance guy I suspect is the slowest mechanic on earth because he is so meticulous and caring, he definitely fixes less cars in a day because he has zero rush.

There are loads of smart folks doing great work all over the world but don't have a YT channel, ya know? Just showing off and being charismatic on YouTube doesn't make you smarter or better than someone else that doesn't have a YT channel. He plays to the algorithm surely you can see that?? That's part of the recipe to build a successful YT channel.

It's true modern engines rely on their oil more than before (VCT etc.) but oils have got a lot better over time as well. Ahmed is not the best at applying logic and science to his recommendations.

 

Also flossing teeth is recommended every day and not every other day. By your philosophy going against recommendation would be to floss 2 plus times per day.

 

Is it that much of a deal? Go ahead do the oil change now and it should be ok. I changed my audi's oil after 15k kms when the oil in there was rated for 5k.

 

Just to throw more anecdotal experiences into the mix, to further complicate things - I changed the oil in my 2017 ES300h every 10K miles, going to 12K miles several times because the oil still looked really good and I was using Pennzoil Platinum which I figured might be better than the average oil. I sold it at 270K miles (used it to drive Uber). Didn't burn or consume any oil. Oil color still faded very slowly to the point where after 10K miles it looked similar to my Acura TL oil after only 2K miles.

There are so many considerations, all of which have been argued ad-nauseum on forums like bobistheoilguy.com. For example, heat cycles would be much less in this situation since I would put 200-400 miles on the car in a day, which is a lot more than the average heat cycle of 30 miles to work or 5 miles to the grocery store. I also drove like an old lady, trying not to go over 2K RPM in order to get the best mileage. The hybrid thing could be argued both ways. The engine starts and stops more frequently but how much of that 10K miles is the engine actually operating? I'd say around 80% or so compared to a regular car. Maybe less because it also turns off at traffic lights, drive thru's or situations when other cars would be idling. So you have nearly no regular idle operating time compared to other cars. And who's to say that the oil rings didn't wear quicker in this situation because of less frequent oil changes, but that they hadn't yet worn to the point of burning oil? Maybe it will start burning oil at 300K miles whereas it would have lasted to 400K miles had I changed it more often?

Ultimately I decided to go to a 6000-7500 mile oil change interval on my '22 because I'd like to push it to at least 300K. But it certainly wasn't based on my experience with the '17. I feel like the two are somewhat different situations because the engine in the 7th gen ES is a different animal than the '17. The dynamic force engine has only been out for about 4 years. Who knows what could happen in the long term. Also, it uses 0W-16 rather than 0W-20 that the 2AR-FXE in the 6th gen did. Those two factors are enough to convince me that the two scenarios aren't exactly comparable.

 

Test your oil to make sure it can handle 10k instead of debating with no real data.

 

You wouldn't change it at 1k because it's too frequent. By that argument, instead of changing it at Toyota's 10k, why not change it at 20k? lol

It's oil, folks. It's cheap!

Part of the reason the 3rd Gen prius had so many engine failures, many believe, (including Car Car Nut Ahmed) was partially due to the oil not being changed enough due to the 10k oci.

^^and good point. the new engine is untested. actually i have a photograph with an entire wall of Dynamic Force 2.5 Hybrid engines (same engines in ESh) with failed heads. i'm talking dozens. stacked. there's some patterns starting to emerge on this. i'll see if i can dig it up again. i'm in a mechanic's group.

 

Question on the oil - my 3.5 liter engine shows that it requires 0W20 synthetic oil. Most of the stores that carry that weight have 0W20 but show that it is for hybrid engines only. What is the difference between 0W20 for hybrid and standard engines?

 

marketing differences

 

Hi to all, hope this does not start another flame war over intervals. Not my intention, as I have already made my mind; and don't mind the additional expense $ for my peace of mind.

I have over 1,100 miles on my brand new, 4 month old, 2023 ES 300h. I wanted to change the oil and filter since I smell a little bit of fuel in there, and dip stick shows a little bit over max. Unfortunately, the dealer refused until at least 5K or 6 month (first scheduled maintenance) under sever conditions.

So I want to perform the change myself but I'm having trouble identifying parts needed. Are these the correct parts:

• Oil: 0W-16 *Will be using Mobil 1 Advanced Fuel Economy Full Synthetic
• Filter (Toyota): 90915YZZN1 ???
• Drain Plug Washer: 9043012031 ???

Anything else I'm not considering?

I will send my 1st and 2nd oil for analysis to post here or new thread. Then probably every other change just for fun .

Thanks!

 

Take her for a hard run and burn off the fuel.

 

Why not just pull the dipstick and have a peek at the condition of the oil?

 

Every owner has his own style for maintenance and, of course, you’re certainly entitled to pursue whatever level of conscientious ownership that makes you feel comfortable. I’d complete this first oil change and then every 5-7 thousand miles thereafter and you’ll be fine.. Enjoy your car. The way you’re caring for it, it’ll last you well over 100,000 miles, I’m sure.

 

I actually did that yesterday. A little bit of fuel smell and the oil level just somewhat above the full mark. So I think there must be some fuel dilution as I usually do short trips and heavy traffic idling.

Just want to make sure I'm ordering the correct parts.
