Maybe the RC isn't as critical ! Or all 0w16 is RC. It does list the 2019 rav4 Hybrid.
Mobile doesn't show their oil as being RC spec which the owner's manual clearly states on page 661 as being the requirement, whether anyone thinks it's critical or not is a moot point, Mobile has a bunch of oil on that list that is RC spec, and a bunch more that isn't.

Doesn't the 2018 /19 Camry Hybrid have the same engine? It's also listed .

Anyway , The OP should have free oil changes until the RC gets put on the label
Since when should we trust an oil company? :shrug: The API donut shows the Mobile 1 Advanced Fuel Economy not having the RC spec that the Toyota oil does show.

The email I got from Mobil confirms their Mobil 1 0W-16 does not meet the Toyota specs. Refer back earlier in this thread.

Conserving resources mean oil may save gas.Thats it..Mobil exellent full synthetic oil mix Pao an gtl.With very strong base.I purchased 2 cans and will use on next oc on my RAV4
Hybrid.After brake in 2000ml


“Resource Conserving” applies to oils
intended for gasoline-engine cars,
vans, and light trucks. Widespread use of “Resource Conserving” oils
may result in an overall savings of fuel in the vehicle fleet as a whole

I’ll use the mobil1 it’s oil. The RC isn’t gonna affect anything other what maybe 1mpg if that. When i do my oil change I’ll update on my mpg. I already track it via an app. My money is on no difference. I bet it’s just marketing

That would be my guess. it was used to get every last MPG they could get. Oil is a very touchy subject for many people. Change intervals and brands always get people going. I say to each his own!

I have never thought to check for RC designations until reading this thread but as others have stated, its most likely for additional fuel economy which is funny because we are talking about 0w-16 oil here where its whole development is based off of increased fuel mileage.

I have a bottle of Toyota 0w-16 oil in my garage (my oil was low from the get go and the dealer wanted me to book in a service appointment....ummm no) However, my bottle looks different. Not sure if its a Canada/US thing but just out of curiosity i will check for the RC rating tomorrow.

I am also in the camp of doing all my own fluid changes. I pass up on all the free oil changes because i hate stealerships and i have seen and experianced all the mishaps of a simple oil change gone wrong. This was when i used to drive fleet vehicles and used to take them in for service. Stripped oil pan bolts, overtightened oil filters, sometimes oil filters not changed, major oil overfill, oil underfill, oil caps left off under the hood...etc. It is true that it is generally the apprentices or straight out of high school kids on the oil change duties and typically dont care or are just learning.

No, that's not "it". Have you read the other posts on this thread?

Yes, oil discussion is usually chaos.

Has anybody read the tests or white paper on what makes an oil RC compliant? It takes a lot of money to have an oil certified to be able to put a marking on the bottle, so there has to be something very tangible to make it RC.

The bold part below is interesting.

This might have it...but I am not spending 80+ to read it.

Classification of Energy Conserving Engine Oil and Resource Conserving Engine Oil for Passenger Cars, Vans, Sport Utility Vehicles, and Light-Duty Trucks J1423_201502


This SAE Recommended Practice was developed cooperatively by SAE, ASTM, and API to define and identify Energy Conserving or Resource Conserving engine oils for passenger cars, vans, sport utility vehicles, and light-duty (3856 kg [8500 lb] GVW or less) trucks.

Bpedit posted the qualities of the RC spec in post number 2 which many here apparently didn't read.

https://www.oilspecifications.org/articles/api-sn.php

The Resource Conserving supplemental category requires further properties. The former supplemental category, which was called Energy Conserving required only fuel saving properties from the oil. Resource Conserving requires further properties like:

emission system protection
turbocharger protection
compatibility with engines operating on ethanol containing fuels, up to E-85


You want 0W-16. The Mobil 1 0w-16 is rated for API SN but there is no mention of the RC part. The Rc is evidently a suppliment to the SN:
Resource Conserving requires further properties like:
emission system protection
turbocharger protection
compatibility with engines operating on ethanol containing fuels, up to E-85
See: https://www.oilspecifications.org/articles/api-sn.php

The Mobil site has a search function for the appropriate engine oil but the 2019 Rav4 is not listed. I've just dashed off an email to them to hopefully confirm. Here's a number to call as well: "Call 1-800-662-4525 to ask a technical question about Mobil™-branded products". I'm a fan of Mobil oil so if this checks out I won't be looking further. I can't imagine the other Toyotas that are on the list wouldn't also want the above properties sans the turbo protection.

The OEM Toyota filter is part numner 90915-YZZM1 That's what the dealer sold me anyway, the 90915 checks out but I can't access the remainder of the number on my vehicle's current filter. The size and shape match. It was only about $9 at the dealership.

Edit: None of the genuine Toyota 0W-16 I see for sale online, ebay and Amazon anyway, shows RC.

That doesn't show much more than what I put. Its general and not specific. I want to see what specifics make it an RC. Extra cat protection? How is that tested? Less soot? Less oil particle vapor? One ingredient more than another or a substitution of something for another?

Compatibility with E85? Meaning current oils don't? Something needs changed in the additive package to make it more stout (hmmm, imperial stout :) ) to withstand more corrosive E85?

I am not picking a normal oil argument but looking for what qualifies is detail. Other than Sequence VID and TEOST33 there is no difference in that graph between the older spec and the new spec + RC. Has to be more than that I would think.

The requirements of API SN with the Resource Conserving supplemental category are identical to the requirements of the ILSAC GF-5 standard.

Based on this information Any Ilsac Gf5 oil meet Resources conserving requirements

I really goofed up on my original post. I meant 0W-16. I guess I was thinking of the previous gen using 0W-20 and ended up up w/ 20w-16, or whatever wacky thing I typed.
