Mazda responds 5w-30

Tried to get a answer from Mazda about warranty coverage if using 5w-30 in the USA. Initial response they said 0w-20 was mandated for better mileage and using another viscosity “can” lead to possible rejection of warranty.
I pushed them to answer whether if I follow the severe duty schedule, change every 5k with full syn 5w-30, whether my warranty would be invalidated. Response:

“Thank you for contacting Mazda Customer Experience Center.

Hello again, this is XXX from the Mazda Customer Experience Center.

I will include a few documents that provide more information regarding the maintenance of your vehicle. I will include a link to the full documents below as well.

You are responsible for properly operating and maintaining your Mazda Vehicle in accordance with the instructions described in your Owner’s Manual. If your vehicle is used under severe driving conditions, you should follow Schedule 2 of the maintenance requirements described in your Owner’s Manual.
? Maintenance Records - Proof of Maintenance
To continue warranty eligibility and to protect your investment, it is your responsibility to properly maintain your vehicle according to factory recommended schedules outlined in your Owner’s Manual. As part of this you must keep your maintenance records, receipts, repair orders and any other documents as evidence that maintenance was performed. You must present these documents, should any warranty coverage disagreement occur. Failure to do so can result in your warranty being voided either in whole or in part.

Only use SAE 0W-20 oil “Certified For Gasoline Engines” by the American Petroleum Institute (API). Oil with this trademark symbol conforms to the current engine and emission system protection standards and fuel economyrequirements of the International Lubricant Standardization and Approval Committee (ILSAC), comprised of U.S. and Japanese automobile manufacturers.

If you live in the United States it requires SAE OW-20 oil with the Certified for Gasoline Engines stamp by the API.

If you live in Mexico use API SM or higher, SAE 5W-30 engine oil. If SAE 5W-30 engine oil is not available, use SAE 5W-20, SAE 0W-30 or SAE 10W-30 engine oil. The quality designation SM, SN or SP must be on the label.

Please contact us back if you need further assistance. Thank you for being the best part of Mazda and have a wonderful day.”

“Requires” 0w-20’ in the US. Cross the border and magically 5w-30, 5w-20, 0w-30, 10w-30 are okay!
What bull! We have to use a thin oil due to CAFE, and they admit its for mileage, while admitting the 2.5 runs fine on most common viscosity’s. Which we all knew
So debating whether to go with this crap for 60k, which may lead to more wear, or use my preferred 5w-30 and chance warranty issues. Leaning towards saying screw it, and taking my chances. I’ve driven over a million miles and never had a engine failure, or even had a engine burn oil. I need to get 200k out of this car
 
What year is your CX-5? NA engine?

You're not chancing much. Go with 5W30.

Let's take a look at what Mazda actually recommends for the Skyactiv 2.0, 2.5 engine!

hmmm....
 
Oh, and let's not forget to ignore that all these oil weights are fine for 40c plus, that's BS. lol
 
They want us to use thinner oil in the USA to meet the strict smog laws that they agreed to in order to sell vehicles here. It has nothing to do with whether or not it will damage your engine in the long run. We are the puppets and they control the strings.
 
go to walmart buy 0w20 get the reciept photo copy it and then return it and get the oil of your choice.
With how well-made the drivetrains in these cars are, it's unlikely you'll ever need to use the warranty. Save for the horrid CD cyl. head-crack issues.
 
We've been around this barn too many times on the forum, on Reddit, and on Facebook. The answer isn't changing.

The motor is the same in all countries so physically, oil requirements are not different except with consideration to climate.

And Mazda isn't going to give you a different answer. As a corporation, they are going to keep their messaging consistent with their manuals, which are designed with regulations in mind. They would not be consistent to have cars set up for testing emissions and economy with certain fluids, only to tell users they could use thicker fluids, which would give different results.

I put a lot of miles on and have been driving since the 70's and in all this time I have never had drivetrain issues on any vehicle I have owned and I have only used whatever the make recommended. I have owned 5 3.6 pentastars which are known for issues and I have never had an issue (knock on wood) but I only use what they recommend PUP 0w20 and change early.

amen.
 
My 2017 NA 2.0 used 0w20 every 7K/8K miles for around 160K miles at typical mpg. If I knew better, I would have switched to 5w30 every 5K miles much sooner.

It really sucks to have this worry/concern hanging over our heads. I was lucky that nothing went wrong during the warranty period. At 20K+ miles per year, it was gone pretty quickly. 🤦
 
If your vehicle is used under severe driving conditions, you should follow Schedule 2 of the maintenance requirements described in your Owner’s Manual.

It's a good thing your vehicle use meets the criteria for severe driving conditions ;)
 
The maintenance requirements for severe driving conditions represent a higher standard of care for the same engine. It would be difficult for Mazda to deny warranty coverage on the ground that the owner has been more careful/diligent than most. 🤦
 
To me it is. It's not in the 2016 manual. Doesn't spec anything past 5w-30 anywhere in the world for that year.

We are all well aware, what's stated in the owners manual is regulated by CAFE for 0.2mpg fuel savings, NOT based on what the engineers designed the vehicle around.

It's helpful to know what the engine is actually specified for, and , to consider the statement: "tight engine tolerances" as complete and utter bull, and to stop worrying about using 5w30 when the engine was clearly designed for weights beyond that. 5w30 is also a weight that was pushed by CAFE not very long ago, actually.

As for actually going beyond 5w30? I'd run 5w40 or even a 10W in hot weather. Done it before, would do it again.
