Toyota Recommended OCI for 2006 Highlander Hybrid

[paulri]

I would like to know if anyone here knows Toyota's official OCI recommendation for the 2006 Highlander Hybrid. The manual says 5K, but that was assuming conventional. I know that Toyota has since backspecced some vehicles to 10K if they run synthetic (that is the case with my Sienna).

I called 5 Toyota dealers nearby this afternoon, and 3 of them told me it was 5K, regardless of conventional or synthetic, and the other 2 told me it was 5 conventional, but stretched to 10 if synthetic.

Does anyone know for sure--and not that i'm trying to be argumentative, but if you could give me a link or source for your information, that would be great. 3 to 2 just doesn't inspire much confidence, that's all.

10k with synthetic, 5k with dino

Interesting--I just found this, at http://toyota.custhelp.com/app/answ...-change-intervals-using-synthetic-oil%3F :

What are the oil change intervals using synthetic oil?
Only Toyota vehicles in which 0w-20 synthetic oil is required (except 3UR-FBE Engines*) have been approved for extended oil change intervals of 10,000-miles/12-months. (However, you should continue to check the oil level regularly and top off if needed. That will help your engine get the full benefit of synthetic oil.)
Vehicles in which 0w-20 is an option to 5w-20 mineral oil, (or 5w30), will continue to require 5,000-mile/6-month oil change intervals, even if 0w-20 oil is used.http://toyota.custhelp.com/app/answ...-change-intervals-using-synthetic-oil%3F

Since both my cars were given the option for 5w20 or 0w20, I guess that means that Toyota still recommends them to go only 5K? I know that is absolutely not what I've heard from my local dealer, about my Sienna.

Where did you get this from? That is what I always heard from my local dealer for my Sienna, but that does not align well with what I found on that customer service website.

This I would consider to be the horses month. Due to the age of vehicle, I would not count on Toyota in changing there recommendation or requirement. However, if your interested in doing extended OCI, I don't believe that to be out of the question either, and especially for a hybrid. Buy a full synthetic 0w30 or 5w30 and likely good to go to 10,000 miles. If you really want to make sure, do an oil analyst.

I might do just that. In the last year or so, I had gotten accustomed to a 7000 mile OCI (before, I was taking them to 3-5K). It doesn't seem to make sense, to pay Blackstone $28 to take a $20 DIY oil change from 7000 to 10,000 miles. But if I decide to fall back to 5K per OEM recomendation, then doubling the OCI with a used oil analysis does make sense. I'll see how far I feel comfortable going without a used oil analysis. I might just stick to my 7K OCI and not do the used oil analysis. I would like to see if there is anything more "official" than what I dug up, however....

The reason for this is a larger oil capacity, and rollerized valvetrains that aid the vehicles recomendi g 0w20 to go further. It has little to do with the oil and more to do with an engine that is less harsh to the oil and therefore it lasts longer.

I just checked, and the 2011 2GR-FE engine has 6.5 quarts capacity, instead of my 5.0 quarts. Interesting. I simply assumed that this was a short OCI for conventional, extended OCI for synthetic. Well, learn something new every day.

You have to also remember that those shorter OCI were recommended on conventional, where the synthetic is an extended OCI.

Yes that is true, but it is also the case that Toyota has insisted that this engine stick to 5K intervals, even with synthetic.

[/quote]Yes, you are right with what Toyota says. For your 2006 Toyota Highlander Hybrid, they say to use API SL 5w30. To the engineers, any API SL(Now SN+) 5w30 are the same. All BITOG knows they are not. Most baseline synthetic could do at least 7500 miles.

My observation with Toyota's oil recommendation in the OM are really specific about which oil to use. The OMs usually do not mention conventional or synthetic at all. Its at this site where they do: https://toyota.custhelp.com/app/answers/detail/a_id/7604/~/what-are-the-oil-change-intervals-using-synthetic-oil%3F But it really only adds confusion to what they are really are telling you. First of all, they answer there question based on the OEM motor oil they sell, not on what is all available to use that is acceptable. Like on my 2017 RAV4 Hybrid where they recommend the 10k OCI on ILSAC GF-5 0w20. The OEM oil for that is a full synthetic. But out there on the motor oil market, there are a few synthetic blends, like Pennzoil Gold and Valvoline Maxlife, their 0w20 passes that spec. Toyota really doesn't need to mention conventional or synthetic.
