0W16 oil?

i have a 2019 XLE and just noticed it uses 0W16 oil. I went to 3 auto parts stores and they never heard of it. Is this something new or can 0W20 be used?

Lots of discussions on 0W16 oil, it's the required oil for the 2.5L Dynamic Force engine since 2017 in the 2018-on Camry and 5th gen Rav4, read the manual, 0W20 can be use temporarily if 0W16 isn't available, which it is from Toyota, Valvoline and others by now. Last I checked Mobile 1 made it too, but it wasn't RC spec'd which also is a requirement.

FYI, the Mobil 1 0W-16 Advanced Fuel Economy product meets these specs (copy-paste from their website):

Applications

Mobil 1™ 0W-16 is recommended by ExxonMobil for SAE 0W-16 applications in gasoline and hybrid engines designed to operate on SAE 0W-16 viscosity motor oil.
• Mobil 1 0W-16 is engineered for use in select Honda and Toyota gasoline and hybrid engines where this viscosity is recommended.

Specifications and Approvals

This product meets or exceeds the requirements of:
API SN
API SN PLUS
API SJ
API SL
API SM
API SN Resource Conserving
API SN PLUS RESOURCE CONSERVING
API SP
API SP Resource Conserving
ILSAC GF-6B

I don’t think I’d use Walmart oil. My dealers parts department had it, but I didn’t check the price.

Locally, Toyota & Honda dealership should have them. Over priced if you are a value shopper like me. Buy filters there though.

Walmart as Mobil 1 (roll back right not at $22.88) or Supertech at $14.88, and both looks to be in store stock for my location.
Not sure, there may be a M1 rebate to tag on to: Rebates & Promotions | Mobil™

Napa has Valvoline: https://www.napaonline.com/en/p/VAR878399?

AMSOil olnine: OE 0W-16 Synthetic Motor Oil OES - AMSOIL

Amazon will have anything, it's where I got my Pennzoil.

Really nothing wrong with Wally brand Super Tech, made or distributed by Warren (long time company) and is well tested and analyzed by many these days.

Good luck on research.

I have been trying to find out what is different about "resource conserving" and all that consistently turns up is almost everywhere is either the propoganda verbiage from API or that it saves gas. The closest I can find to an actual definition is from API's own pdf:https://www.api.org/~/media/Files/C...rtification/Engine-Oil-Diesel/Publications/MOTOR_OIL_GUIDE_120116_FINAL_WEB.pdf

"SN Current Introduced in October 2010, designed to provide improved high temperature deposit protection for pistons, more stringent sludge control, and seal compatibility. API SN with Resource Conserving matches ILSAC GF-5 by combining API SN performance with improved fuel economy, turbocharger protection, emission control system compatibility, and protection of engines operating on ethanol-containing fuels up to E85. "

So if I am reading this correctly, ILSAC GF-5 is SN + Resource Conserving? Anyone car to weigh in or actually have technical data for or against this - rather than marketing bs?

In short, the old standard was called API SM Energy Conserving and was only focused on fuel savings. When API SN Resource Conserving was introduced it was a series of tests designed around emission system protection, fuel savings, higher ethanol fuels, turbos, etc.

If an oil passed all the SN RC tests, then yes, it was ILSAC GF-5 which has been phased out on the first of this month and replaced by the even more stringent GF-6A and GF-6B standards. For our vehicles, you will want to be looking for GF-6B when it hits the shelves.

I heard from a Toyota Technician that the RAV4 has an electric variable speed oil pump. The flow rate is calibrated for 0-16W. It may not be as readily available as other weights, but I still find it fairly easy to find. Amazon always works too.
 
#23 ·
YouTube "The Car Care Nut" channel is a dealership master Toyota mechanic and has posted many very worthwhile 5th generation Rav4 videos. On one he specifically discusses the electric oil pump on our 2.5 Dynamic Force engines and explains that indeed the car computer controls it and changes its rpms and pumping volume continuously and that it is a big mistake to use anything other than 0-16W as it screws up the computer control function.

Nowhere in the manual does it state that using a higher viscosity could damage the engine. Il even suggest using higher viscosity under more extreme conditions like towing. I live in Florida and I'm using moble 0w30 with no problems my mpg actually went up notch.
 
#30 ·
The Car Care Nut also says to go 5k, not 10k between oil changes and change every 6 months. I'd probably split the difference and as a low mileage drive go 5k and within a year. For those that go 10k be sure to check oil level.
 
#32 ·
The Car Care Nut, the Rav4 manual and all online oil info also state that oil changes depend upon time, not just miles. In the Rav4 using synthetic oil it MUST be changed at least once a year regardless of mileage in that period of time. This is because all engine oil-even synthetic- absorbs moisture from the air and becomes contaminated. With non-synthetic oil it can turn milky and foamy if you leave it in too long even if it is low miles.

I love the people who are smarter than the Toyota engineers and use what ever viscosity they want. I read you can use 0-20 in a pinch but change back to 0-16 on the next change.

I also love the cheapskates who shell out $40K for a car and then "save money" by streching the oil change intervile to 10-15K miles. A synthetic oil change is $75, do it every 5K miles or at least once per year.

Who here beleives in the "lifetime" trans and diff oils? Lifetime means the length of time Toyota is on the hook to repair/replace it, not what's best for the car.

It's for fuel economy only. My 2008 rav4 said the same thing 0w20 but I've only used 0 or 5w30 over 600,000 miles and never had an issue with the engine and still drive it 250 a day. I have a 2020 rav4 and use 0w30 47,000.
Please provide a reference from Toyota that substantiates this.

And sharing your anecdotal experience is not scientific evidence that the millions of other Toyota owners will have the same result.

And why does Toyota reduce the oil change interval from 10,000 miles to 5,000 miles when using any oil other than 0w16?

A higher viscosity may reduce mpg at longer intervals. Toyota has yellow warning flags all over the manual but none that says a higher viscosity may damage your engine. Bottom line is if you live in a higher climate area use increase viscosity in cooler use 16.

A higher viscosity may reduce mpg at longer intervals. Okay, whatever that means.

Toyota has yellow warning flags all over the manual but none that says a higher viscosity may damage your engine. So this means nothing to you "Your vehicle is certified with Genuine Toyota 0W-16 motor oil. For VEHICLES CERTIFIED FOR 0W-16 motor oil, the oil change interval is 10,000 miles or 12 months IF 0W-16 MOTOR OIL IS BEING USED. If 0W-16 is not available, 0W-20 mineral oil may be used. However, it must be replaced at a 5,000-miles or six-month INTERVAL with 0W-16 motor oil"

Bottom line is if you live in a higher climate area use increase viscosity in cooler use 16. Our OMs must be different. I don't see where mine specifies this.

0-16 oil is not really 0-16 viscosity, they named it that way to make a different spec instead of saying 0-15 with xyzxyzx spec. Caracteristics of the oil is different, less friction etc etc
 
#44 ·
It's all about meeting their mpg requirements if using higher viscosity could damage the engine they would just say it. Warmer regions should use higher viscosity I live Florida and use 0-w30 in my 2020 xle for at 20 thousand miles now no problems. I always used 0-30 in my 08 rav4 instead of 20 I now have over 600 thousand never had an engine problems.
 
#47 ·
You can use whatever you want, but I think Toyota knows better about hot Florida weather and how it affects their engines than you or I. The fact that the manual strongly advises draining non-0w-16 oil suggests engine damage, if not then hits to longevity of the motor.

Our engines are calibrated, having tolerances conceived for very thin oil. Adding thicker than required could cause problems far, far after 20,000 when you perceive "no problems".

What oil one uses should never be an emotional decision...its a technical decision...just like wearing masks and social distancing should be a health issue, not a poltical issues.

Here's a great explanation for the 0W16 oil selection.

The video starts at the lubrication section:

This is what will use for my 2021 RAV4;
Unfortunately my local dealer only offers 0W20 but I don't want to go that path. Seems it meets also latest standards API SERVICE SP and
ILSAC GF-6B

On the same page it also says under more extreme you an oil with a higher viscosity may be more appropriate. I drive around 250 mile a day in hot Florida weather so my situation is different, for everyone else use 16. My mpg when up the first time used moble 1 advanced fuel economy 0-30.
 
#50 ·
I see where the OM refers to "extreme load conditions" and "high speeds" but nothing about daily distance traveled in hot weather. What page are you looking at? Are you pulling a trailer while exceeding the posted highway speed limits?
