Alternate 4Runner Oil - 05/22/18 01:54 AM

Have a 2017 4Runner. Manual recommends 0W20. I live in Tucson, AZ and would like to run a higher viscosity, like a 5W30 syn. Manual leaves no room for alternates under different conditions except, for Puerto Rico only. Higher viscosities OK. A little confused? Is the Puerto Rico engine of a different specification or is it just gas mileage/environmental? Any opinions on a higher viscosity causing potential harm?

Still under warranty, I would stick with what Toyota says.

I have Mobil 1 0w40in my 2018 trd Pro 4 runner right now. The dealer installed it at my 6month service when I brought the oil and truck in. Had a discussion, pointed out the owners manual and they didn’t have a problem with it.
I am going to change my 0w20 in my Tacoma to Castrol magnatec 5w30 @the 5k Service.
The manual specifically says higher viscosity may be better suited if you drive @ high speed or high load conditions.

The Puerto Rico, Aruba, Bonaire models are the same as the USA models.
Now. If the truck is the same, what is different?

Engine is a 4.0L 1GR-FE?

My 2015 has the same engine, and in 2015, it was spec'd for 5W30.

But stick with factory spec for warranty and then you can switch.

Re: Alternate 4Runner Oil - 05/22/18 02:19 AM

Stick to the what the manual says for warrenty purposes. This is like Nissan Versa - Versa always called for 5w30 now Nissan says 0w20. No changes were reported to engine design.

Yeah don't listen to the engineers that designed the motor...you obviously know better than them right?

Get out of here with that baloney. Have you read the owner's manual? Didn't think so.

I also have a 2017 4Runner. Toyota's requirements with regards to oil viscosity is not specific (recommends vs requires) and gives plenty of leeway to where you can run just about anything you find on the shelf at WalMart.

Mine will be getting 5w30 (coming up on its first oil change this week, actually), as that's what I have on my shelf. My 2005 (purchased new) has the same engine and has run flawlessly for 136k miles on Xw30s and 40s.

Here are the pertinent sections of the OM:

That’s why I run 40 and 30 weights in the gr motors. that’s what they are engineered for.

Bunch of good workers in here.

Puerto Rico is well known as a center of engineering excellence so you should be doing what they do. It's a good thing they discuss the use of motor oil at extremely low temperatures in Puerto Rico because it may be so cold your engine might not start. Thank goodness Toyota has addressed this.

Re: Alternate 4Runner Oil - 05/22/18 03:55 AM

I like 0w stuff. 5w stuff ain't that much different; flows a little less when cold.
My guess is, 5w30 use will result in slightly worse gas mileage.
Other than that... Nada.

Re: Alternate 4Runner Oil - 05/22/18 03:58 AM

I was curious about my car. Shell Puerto Rico specs 0W20 with no alternates for my Accord just like in the US:

Accord Coupe EX-L 2.4 (Accord Coupe) (G) (2012)

Premium Helix Ultra SN 0W-20
Quaker State Ultimate Durability SAE 0W-20 Full Synthetic Motor Oil

Re: Alternate 4Runner Oil - 05/22/18 04:10 AM

Why don't you feel 0w20 will be suffice? confused

Re: Alternate 4Runner Oil - 05/22/18 04:33 AM

Maybe buy a six pack of Mobil 1 15W-50 and add a bottle of it with each oil change? Manufacturer will have no idea, but certainly not the best approach. How big is the sump?

5W and 0W have very little difference in actual cranking and pumping rates until you get REALLY cold.

The nuance is easy to read here. The oil temperature chart for Puerto Rico is the unregulated () recommendations. This is how the engineers were able to communicate what they recomended around CAFE language requirements. It is a gift.
Another tell is to go to the Castrol Australia oil selector and see what is Recomended in other markets for the same engines. The engines are built to the same specifications worldwide. http://www.datateck.com.au/lube/castr_au/

We should not confuse regulatory driven language with engineering best practices. They are not to the same purpose.

Toyota designed the GR engine to run on ILSAC multi Grade oil. (5w30 on initial design)It will tolerate up to 15w40 and down to 0w20. It will also run well on Acea a3 selections as they fall within the heavy , fast, hard and hot running range of selections that are preferable in tougher climates.

Toyota must have changed the verbiage.

My Mom has a 2015 TRD Pro and the manual states 0w20 under normal conditions. A 5w20 can be used if 0w20 isn't available, but 0w20 must be used for the next oil change. If the vehicle is used for towing, you can go up a weight. (Be it 0w30 or 5w30.. who knows what they meant.)

I am finishing up a small 0w20 stash then I plan on running a 5w30 synthetic. 10k OCI's.

When i owned my 2017 Corolla and asked the service mgr about this language he said "sure, you can go with higher viscosity, but by doing so you are saying that you're vehicle is being used under extreme conditions and you now fall under severe service intervals for all maintenance items". Good luck, i think the 4Runner will be fine with a variety of viscosity, including 0W-20.

For me personally, I would use 5/30 in a heartbeat, I would ditch the 20 right away. I did years ago on my wifes Mazda Skyactive engine.
Same deal with Mazda 0/20 or 5/20 (I forgot which) in the USA but everywhere else in the world 5/30. Its all about the EPA.
and to make matters worse you live in a much warmer climate then northern states (as I do) so I wouldnt give it another thought. Do it.

Re: Alternate 4Runner Oil - 05/22/18 11:55 AM

Yes I read the manual. While the example with 0W20 oil states higher or lower viscosity might be used under different conditions, they make a point of stating should you use 5W20 due to lack of availability of 0W20, you should switch right back to the 0W20.

Thanks for that link as it shows that in Australia a 5w-30 is recommended for the Lexus LX570 with the 5.7 liter engine (3UR-FE). Now, I do not own a LX570 but I do own a Tundra with the same 5.7L (3UR-FE) engine. My OM throws the same verbiage out that a higher viscosity may be better suited at higher speeds or extreme loads. I don't really have a problem with the 0w20 but IMO, a 5w30 *may* offer me a little more protection?

Thank you Bryanccfshr. This is what I've been trying to say unsuccessfully for awhile and you nailed it. The ENGINE is specified for various oils by the manufacturer, and CAFE in the US requires the 0w20 spec.

I appreciate the posting of the Puerto Rico chart for our engines....that is what would have been in the manual without CAFE.....but instead we get this:

Not to say that mom's short tripped grocery getter won't be fine on 0w20 - it will rarely get up to temp anyway.

I'd go by Puerto Rico recommendations.

In my older Toyotas, I use either 15w-40 or 10w-40. In my newer Toyotas, I use 5w-30

I would choose an oil based upon the type of service and environment you will be operating in. To be honest the difference between 0w20 and 5w30 (both being ILSAC) is going to be very, very small. You as a driver /owner will not be able to detect a difference. Variables such as ambient temperature and winds do much more to performance and mileage.
So yes if it were my tundra I would run 5w30. If my wife short trips a GDI engine I would run 5w30. If I run very hard up and down mountains or tow a heavy trailer a lot acea a3 rated oils such as Castrol or Mobil 1 0w40s seem to be built for this.
If I run on nasty, dusty rough roads(collechee in West Texas with opposing heavy truck traffic) this is a reality for my Tacoma)for half my mileage I look for a bargain quality 5w30, 10w30or 40wt. And run it on the “severe” service schedule.

Re: Alternate 4Runner Oil - 05/22/18 05:16 PM

Seeing as the manufacturer is only concerned with the engine lasting thru the warranty period, it is in their best interest to advise the thinnest possible oil to get them across that line while driving their CAFE numbers down..It is simple really. THAT is what the engineers have to recommend.

Re: Alternate 4Runner Oil - 05/22/18 05:41 PM

Keep in mind that I live in Tucson, AZ. 105 degrees (and higher) is quite common for many months. Early morning winter might see a freeze like 30 degrees, but quickly move up to the 50's and 60's in the afternoon. In my last 2012 4Runner I went by the book with the 0W20. Traded it in with 38K miles without any issues. My 2017 has 7K miles on it now and I think I'm going to the M1 0W30 going forward 12 months year. While I don't tow or do much off-roading, we do travel to the White Mountains which involves a bit of climbing through elevations. Again, I consider the weather alone severe condition.

I would agree with that.

I have been told by a few auto mechanics, that in western WA state, just driving is severe service given the nature of the traffic, hills, etc....

Re: Alternate 4Runner Oil - 05/22/18 08:59 PM

With the salt and brine they put on the roads...the sad truth is that this vehicle will rust out before the engine wears out regardless of oil selection.

So in reality I should run 0w-20 and just enjoy the fuel economy benefit. But my hopes are high that the engine will feel tighter and stronger using a 0w-30 as the miles build.

From +30F to +105F sounds perfect for something like M1 10W30. Less shear, lower Noack volatility, less polymer VII load. I agree with selecting an oil based on your climate and application, but I would extend that to include the cold starting winter (W) rating as well as the operational temperature viscosity.

I live in a very similar climate (ignoring humidity) a 10W or 15W oil is more than ample cold starting ability. Just throwing it out there for your consideration

Re: Alternate 4Runner Oil - 05/23/18 11:41 PM

I'm sure most of you are familiar with this best motor oils list; I was not since I'm not since this is my first "deeper dive" into oils. I found it interesting, particularly the Quaker State ultimate durability oil ratings.

http://www.bestsyntheticoilfilter.com/best-motor-oils-complete-list/

This evaluation focuses on wear resistance, or PSI strength which seems to be considered the most important function of an oil. I ended up going with good old Mobil 1 advanced full synthetic 5W30. When reviewing its viscosity specs, at 40 degrees centigrade, it is the same viscosity as the M1 advanced fuel economy 0W30 (which ranks #88 in PSI). And it ranks #3 in this study. I think it will do well in my climate and it is a step up from the 0W20 Penzoil Platinum which I am currently running.

I would take anything from the Internet with 10 pounds of salt.

I bought the 4Runner as a DO ALL vehicle. Well everything but race track. Running the 0w-30 lets me run in the extreme cold and the 30 will give me the extra "cushion" over the 20 if I run it hard in hot temps or do some towing.

I am not concerned about the 1/2% fuel mileage loss with the slightly thicker oil. I am smart about driving and try to maximize fuel economy in other ways.

Also when running through deep loose sand with the engine laboring or running in 4 wheel low I would not feel comfortable with a 20wt.
