I noticed oil interval is 10k, makes sense for a hybrid. The recommendation is for regular oil I think. Since synthetic oil generally lasts twice as long, does that mean I can go to 15 or 20k interval??

Nal puresyn sae 0w20 synthetic oil GF-5/SN was used. Thanks

No. The car takes 0w20 which is full synthetic. There is no conventional oil of that weight.

There is a guy here with a Blue CT, I think he is in the courier business.. He goes about 26K between oil changes. Some have suggested that he change his filter in between but I thinking he only does the filter when he does the oil.

well that's dumb. non hybrids can go 10k with synthetic oil. a hybrid engine is off maybe 30% of the time, so it should go 30% more miles right?
The engine also starts and stops more frequently than a non-hybrid engine, and that can cause a little more stress on the oil. We only have 4.4 quarts.

My BMW went 15K between oil changes, but it took 7 quarts of synthetic oil.

I'm that guy.

If you would like to increase your OCI (oil change interval) past 10k miles, then I recommend you get lab tests on your oil if you attempt it, to be safe.

First of all, like everyone has been implying, Toyota designed the engine with a full-synthetic oil in mind. Depending on how you drive, you may be able to extend your OCI. This is why Toyota recommends 10k OCIs, because they have to account for every type of driver and go with the lowest common denominator.

The oil I use is Mobil 1's Extended Performance, which is rated at going 15k miles between changes (there's a 20k miles version now too). They also make a filter of the same rating, but I don't recommend it as it started to fail around 26k miles. The filter is made of a combination of synthetic and natural media. I recommend a full-synthetic media filter, like the Wix brand I use (part number 57064XP). I have had my oil and filter up to 28k without filter or oil issues.

Keep in mind that my driving style is cruising at 60 MPH all day on the highway (literally cruising, as in cruise control), so my engine doesn't see a lot of hard work. If you are gentle on your car, you can probably easily exceed the 10k factory OCI. Again, I recommend lab tests to be sure. I use Blackstone Labs (https://www.blackstone-labs.com/) myself.

I have my reports if you'd like to see the results.

I'm going 30k on this oil change. Reason being, I'm very knowledgeable, and use the right oil and filter. I used Mobil-1 0W-20, and a Pure One Purolator filter (Note that I did NOT say Pure GOLD). You have to know what you're doing. This specific filter has 5-micron media and is very, very good. The more expensive "Gold" is NOT as good for our cars. I then sent my 15k oil (I drive the car in a way that doesn't beat on it at all) to Blackstone labs for analysis. Analysis showed ok to push for 20k, without any concerns.
So I then went with Signature series Amsoil 0W-20 and a Pure One Purolator filter. I warm the car up most of the time before driving it (pull it out of the garage, pull to the side, and wait the couple of minutes for the water temp to get up to 100-F, while the car is in park and thus has no load on the engine). I rarely have to cold start the engine because I keep it in a garage. This warming up is likely the most important thing I can do. Add up all the minutes I sit warming and I bet it's less time than an extra oil change.

Amsoil is rated for 20k miles, but with pre-warming, hybrid easing engine wear and runtime, and at least driving at very low speeds in my little town, initially letting it warm up a lot before putting much load at all on the engine, I'm really minimizing the most damaging part of the driving cycle. This 30k mile oil change (car has 8k to go with 122k on odometer) will be with Amsoil again (may be that Amsoil is a waste of money, and that Mobil-1 would work fine...especially as someone noted Mobil-1 now has a 20k mile version....mostly related to base levels and acid build-up in oil over time). If my 30k change looks pretty good on oil analysis, I'll continue another 30k. If that one looks good, I'll likely go back to Mobil-1 as it's a lot less expensive and easier to just pick up at Walmart. I'm sticking with Pure One Purolator filter. I'm sure other ones are good (I used Mobil-1 filter previously, and it's good....but not as good as the Pure One) but I'd make sure you're looking at good bypass mechanism and 5-micron filtration media.

I'll let you guys know how it goes with the analysis. I anticipate I'll see a bit more metal than ideal, but probably not anything concerning. Otherwise it's back to 20k change. Once I get a couple of clean oil analyses, I'll probably quit doing them and just have my interval set.

I appreciate not worrying about my oil at even 20k miles, while others are driving around nervous that they're "overdue" at 11, 12, or 13k miles. Learn what to do and how to make sure your engine can run well over a longer period of time. It's not just money, it's a HUGE benefit to not have to change the oil NEARLY as often.

How many miles on the odometer?
