Yes, you can use a 0w20 anywhere a 5w20 is spec'd.

The 20 is the weight at operating temp.

I'd clear it with your dealer otherwise you may be denied warranty in unlikely event you'd have a lubrication problem.
 
Dealers often do not know what they are talking about unless you talk to a tech.

I'd call corporate to confirm. They are the ultimate arbiters of what will be accepted for warranty repairs.
 
If the oil meets the manufacturers specifications. there's no problem. The Ford 5w20 spec #WSS-M2C930-A is a good guide, as Ford and Honda pretty much developed the 5w20 oil spec for use in cars.

For example...

Mobil 1 0W-20 Advanced Fuel Economy outperforms conventional oils and meets or exceeds warranty requirements for many Ford, Honda, Toyota, Mazda, Mitsubishi and Chrysler vehicles. Mobil 1 0W-20 Advanced Fuel Economy is recommended for SAE 0W-20 and 5W-20 applications, and is suitable for the following:

ILSAC GF-4 energy conserving
API SM/CF
Chrysler MS-6395
Ford WSS-M2C930-A

Toyota TSB saids 5W-20 is OK for the 1ZZ-FE engine (for my 2007 Corolla) and 0W-20 weight oil is okay for some other engines but apparently only approves 5W-20 for mine.

My understanding was that 0W20 covers all 5W20 application as well.
In theory they are both 20 weight oils at operating temperature, right?



Um, I don't know about 2007, but Toyota was recommending 0W-20 as well as 5W-20 in their 2008 Camrys...

Do you know that for sure? It's not good to recommend stuff when you're not sure.

My guess is a comprable 5w-20 may have a higher HTHS.
 
Ther's really little real-world difference except when it's -50F.

The Mobil 1 0w20 is 8.6 cSt @ 100ºC, the 5w20 is 8.8 at normal oil operating temps.

From Mobil 1's Website:
Mobil 1 0W-20 Advanced Fuel Economy outperforms conventional oils and meets or exceeds warranty requirements for many Ford, Honda, Toyota, Mazda, Mitsubishi and Chrysler vehicles. Mobil 1 0W-20 Advanced Fuel Economy is recommended for SAE 0W-20 and 5W-20 applications, and is suitable for the following:
ILSAC GF-4 energy conserving
API SM/CF
Chrysler MS-6395
Ford WSS-M2C930-A
It rounds out a lineup of Mobil 1 products that are engineered to help keep your engine running like new. Mobil 1 0W-20 Advanced Fuel Economy exceeds the industry's toughest standards in its class and outperforms all conventional oils. It offers exceptional performance under all operating conditions, pours at temperatures as low as -53°F (-47°C) and protects at oil temperatures as high as 400°F (205°C). It is specifically designed for applications requiring an SAE 5W-20 oil such as most Fords, Hondas and 2005 Chryslers.


From Amsoil's Website:AMSOIL Synthetic 0W-20 Motor Oil is recommended for Honda, Acura, DaimlerChrysler, Toyota, Ford and all other applications where SAE 0W-20 or 5W-20 is required with the following specifications:
API SM/CF, SL, SJ. . .
ILSAC GF-4, 3. . .
ACEA A1/B1
Ford WSS-M2C930-A
DaimlerChrysler MS-6395N


Yep I am sure

So even though the manufacturer specifically says no 0w-20, you would listen to Mobil's website that states "for many Ford, Honda, Toyota, Mazda, Mitsubishi and Chrysler vehicles". Many, not all.
 
Do you know how many cars spec 0w20 from the OEM?? short of a select few hybrids, I know none.
And 0w20 was out way before the hybrid even spec'd it.

0w20 was made to meet 5w20 spec. Thats the only point of it-to be used in 5w20 applications.

Mobil says this on there website:"It is specifically designed for applications requiring an SAE 5W-20 oil such as most Fords, Hondas and 2005 Chryslers."
SO the oil is designed just for applications that need 5w20. Then it gives examples of some car makers that have a 5w20 spec.


If the car maker says flat out(car maker not dealer) not to use it, I would just use 5w20. BUT you can use a 0w20 inplace of a 5w20.
 
I could care less about the oil company propaganda. Look at your beloved Redline and compare the HTHS of the 0w-20 and the 5w-20. It's a huge difference.
 
Propaganda???? This is not marketing or propaganda. If it was it would say "0w20 shows 3x better wear than 5w20"
I just gave you what the oil is made to be used for.

If you dont want to except 0w20 can be used in a 5w20 application I can not help you.

I gave you the specs. The Websites say you can use it, and on the back of the M1 bottles it says if you have a oil related failure useing 0w20 in a 5w20 application they will cover it. Theres not much more to discuss.
 
The TSB for his car only approves 5w-20, not 0w-20 as it does in other models. What more do you need? I find it funny how most around here are quick to experiment with a lighter than recommended oil but when it comes to a thicker oil, the standard reply is always "follow the manual".

On a sidenote, thinking of trying the Mobil 1 0w-40 in the TL.
 
The Mobil 1 0w-40 has the best additive pack. It makes the mpg stipulations of the Euro specs too. I'd actually give GC a try, but the Mobil 1 0w-40 could be good for you.
 
I don't know why this is, every new Toyota I have ever seen says "Use 5w20 or 0w20 oil"

How the TSB could say there is something wrong with 0w20 is still difficule for me to unserstand.

Agreed. As long as this TSB is still current and the mfg's position why would you even consider a 0W-20? They obviously did it for a reason.
 
Is there a benefit to using 0W20 in nyc ?

Unless clarified by Toyota I would stick with 5W20 at least thru warranty. Then do what ever....

Either one would probably get the engine past the point where the body rots out from salt.
