Greeting
Took my wife's 2021 Signature to the dealer for their 5k complimentary oil and filter change. Service manager said that in all Mazda gas turbo engines they use a synthetic blend of oil and that I should not use a full synthetic oil because of the ceramic seals in the turbo. Any other turbo owners have a similar experience and what oil are u currently using? I have been running Mobil1 synthetic in all my vehicles for over 10 years although all engines were NA.
thanks
Gary

 

who makes his stuff up? is there a big warning on the top of your engine DO NOT PUT SYNTHETIC OIL IN HERe or is there a a warning inside your manual????? I suspect not!

 

Grime Reaper would need to fill in about this information because it would have been a TSB or a direct implementation sent by MAZDA Corp to the dealerships. I could not find anything that suggested that requirement. In fact it does not even make sense considering in several parts of the world that Mazda sell and distributes vehicles to don't even have or stocked quantities of any type synthetic motor oil.
What is Mazda going to do.... I can see it lol ..... From Mazda..... I am sorry your country is to poor and behind the rest of the world for having a good stock of recommended motor oil so we can not sell you any of our current model MAZDA's.

Lets wait and see what Grim posts or if any member has information DIRECTLY from MAZDA about this, otherwise it conjecture and guessing the answer. .

 

You rang?

No restriction on fully synthetic oil on turbo CX-5s in my market. Either semi or full synthetic oil recommended. 5w30 or 10w30 in Australia.

 

That's why I never take my cars to the dealership. Their lack of knowledge is astounding.

I use 100% synthetic 5W-30 in my 2021 CX-5 Turbo. The Turbo engine especially needs synthetic because of the higher temperatures in the turbo.

 

IF your not racing or frequently sport driving then the statement is not accurate.
Turbocharged engine ran fine on none synthetic and semi synthetic oils for years. Even in competition use without concern.
Turbocharged engine began getting these myths when so many owners drove them hard and did not allow the turbo to cool down before shutting of the engine.

Plain and simple!

 

I'm sure that there are plenty of honest folks working at some dealerships. Then you get the folks who aren't quite as honest and what they don't know, they make up on the fly.

 

This is true with most things in life. I suspect however that like most dealership the OP talked to a service writer not a service technician in any capacity or training. So what was expressed was wisdom picked up from listening instead of real traing or experience.

And just there is no misunderstanding this is the general description of a "service writer". Notice the highlighted area's.

Car dealerships rely on service writers – or service advisers – to greet customers and inquire about the problems they're having with their vehicles. Dealership service writers then write service orders for service managers, highlighting the technical and mechanical problems that need fixing.


another description:

The service writer is the public face of an auto repair shop or car dealership's repair department. He - because 70 percent are male - is also the point of contact for customers who are inquiring about their cars or about the repairs that need to be done.


How can anyone become a SERVICE WRITER:

The typical requirement for the role of an automotive service writer is a high school diploma or GED





In closing my response, when I worked at a dealership I never liked any of the service writers. Not them as a human but because they generally got information both taking and giving wrong! But I never thought at any time that they deliberately lied. As I said I simply figured they were picking up information in the same way that some people ease drop on a conversation that results in inaccurate and incomplete and many times completely wrong information.

I am sure that GrimReaper having worked at a MAZDA dealership would agree with my response?

 

The SA/SW's are a big demerit in the dealerships service system IMHO. It would be so much more effective to have the mechanic speak to the cars owner directly about the issue rather than relaying it through another person who does not have much, if any, automotive expertise in most cases.

I can give an example from my own life. My technicians take histories on my patients before I see them. It is absolutely amazing how they will be told one thing by the owner while I will get a completely different story when I speak to them as I ask specific questions the technicians wouldn't know to ask.

 

That has proven to be a bad business operation choice for dealerships.

Service writers are valuable and a necessity in most automotive maintenance and repair business. They are not a PIA if they are trained properly like any other job!
The service writers are actually VERY helpful to collect the "BASIC" information so that the auto technicians and mechanic's can actually work on the vehicles and not waste endless time with the customer. That costs the business money and that translate to a higher hourly rate charged to the customer. t has been my experience when many realize it is the mechanic they are talking to than its never only about the problem but many more unrelated questions that tic-toc away at the clock instead of getting the needed repair started and accomplished. I just wish that at most dealerships service writers were a little more mechanically experienced and at least better trained for their job.

I never tell the customers who I am and if asked if I am a mechanic I always reply I just write up what your concerns are and let the mechanic's in the shop go from we write down . Now when the customers is gone I am the one that tells the AutoTech's what needs to be done. LOL If they find something different they come to me and we both look at they car and decide a new plan of action. This thread the example and the situation was what appears to be a service writer thinking that they were being helpful and expressed information that was simply not accurate. Just like many professions where someone other than the actual person doing the work,, procedure or examination someone less experience will be collecting the basic information.
