When I was looking at and buying my '18 GTR, I was told that scheduled maintenance was every 6 months or 5K, whichever came first. Now that I've passed the 5K mark, I was figuring to bring it in for the first time. Calling to check pricing and to compare what they were offering, one local dealer told me that the interval was 7500 miles, not 5000. A couple others said 5000. One insisted that the turbo doesn't use synthetic oil. Others told me that they'd use 0W20 synthetic. WTF?

The manual says that for the US and Canada, the interval is 12 months/7500 miles. That's unless one of a set of extreme use standards are met, in which case it would be 6 months/5000. One of those use cases, though, is "repeated short distance driving." For those of us living in urban areas, isn't that the way it is? I do plenty of freeway drives, enough of which are more than a few miles. But there are lots of short city trips, too.

Anyone clear on which maintenance schedule I should be following for this car so that I can keep it running well and stay in the good graces of my warranty?

I'll make sure that whoever I have do this uses 5W30 oil. I'm hoping that the errant info on oil was more a matter of receptionists not knowing than what they'd actually do in the shop. I won't assume that, though.

I tend to only do dealer service when it's under warranty or it's included in the cost of the car. I'm leaning toward taking this to a nearby high end independent shop I've taken another car to a number of times. They work on everything, though. They aren't Mazda specialists, per se. They're a bit cheaper and I trust their integrity and competence. They said that the car takes 0W20, though. But I'll show them the manual and they'll be fine with 5W30. I think they may have looked up the NA engine when they were figuring out the pricing. Anyway, any reason why I should stick to a Mazda dealer for the first service?

The only thing going on that the dealer might want to look at is that once in awhile, the infotainment system fails to turn on when I start the car. The only way to wake it up is to turn off the power and restart. This has happened maybe 5-7 times in the 3.5 months I've had the car.

Hi,

Here's the link to the scheduled maintenance :
https://www.mazdausa.com/siteassets/pdf/owners-optimized/2018/mzd6/2018-mazda6-scheduled-maintenance.pdf

Schedule 1 is the "Flexible" maintenance (The vehicle calculates the remaining oil life based on engine operating conditions) and Schedule 2 is the "severe" conditions maintenance OR for Canada (from the manual : Canada residents follow Schedule 2).

Schedule 1 is at most : 12 months / 12,000 Km or 7,500 miles
Schedule 2 is : 6 months / 8,000 Km or 5,000 miles

Anyone clear on which maintenance schedule I should be following for this car so that I can keep it running well and stay in the good graces of my warranty?
I would personally stick with Schedule 2 if you do lots of short city trips.

I'll make sure that whoever I have do this uses 5W30 oil.
Correct. For the 2.5T, the manual specify to use SAE 5W-30 engine oil in the USA and Canada.

Anyway, any reason why I should stick to a Mazda dealer for the first service?
No, unless you have warranty stuff to do, like your infotainment system problem you mentioned. Keep all proofs for the maintenance you do, stick to the manual and go to a place you trust.

I know a lot of people here had bad experiences with the dealership. I have a very good relation with my local dealership and I do most of my oil changes there. That's a personal choice. It's a little bit pricier, but they offer me a ride to and from work.

The only thing going on that the dealer might want to look at is that once in awhile, the infotainment system fails to turn on when I start the car. The only way to wake it up is to turn off the power and restart. This has happened maybe 5-7 times in the 3.5 months I've had the car.
If you don't have the Android Auto/Apple CarPlay update, be sure you have version 70.00.100. It's what I have on my Canadian 2018 GT that got the AA/CP upgrade.

Hope that helps !

5w30 FULL SYNTHETIC (due to having the turbo.) The additional heat tolerance (full synthetic) is the important part for a turbocharged engine.

IMHO I would pull an oil sample and see what it looks like at 5,000 miles. If you have no fuel dilution and viscosity is in-spec I'd be ok with the longer interval. If you're concerned about potential warranty issues then follow the severe schedule since you do a lot of city driving.

While it's not "required" (Mazda can't refuse warranty work if you use mineral oil), I agree with your recommendation of using full synthetic oil. And that's what I plan to put in mine.

When the infotainment system fails to come on (actually it's the display screen for whatever mode it's in), I suggest you give the following procedure a try:

Press and hold the following 3 buttons for 10 seconds, Back + NAV + MUTE
That will force the system to restart and should get your screen up and running again. :smile2:
Once it reboots the display should be active and you may have to press MUTE again to un-mute the audio.

Good luck and let us know if that works for you but I expect it will. Seems to be an intermittent issue which occasionally requires a reboot.

I recall reading that somewhere. I can't remember if I ever tried it when the display didn't come on. But I'll certainly do it next time.

I'll check the oil in awhile and get a sense of it. That said, I don't have the experience with what it should look and feel like to make a worthwhile judgment. If it's really dirty, I'll know that much, but it almost surely won't be.

Good call on the AA/CP update. I've got 70.00.021. I wasn't aware of the newer version. Any noticeable changes?

The maintenance screen in infotainment says I'm 2700 miles from needing an oil change, though they recommend maintenance now. The latter is based on mileage. But, other than the oil change, they're not going to do much other than rotate tires and check fluids. Is the mileage number associated with the oil change timing recommendation the system's perception based on the kind of driving I've been doing, or is it a hard wired mileage thing?

Thanks to all of you. This is a big help!

The only way to know unless there's a serious problem is to take a sample and send it to BlackStone or other similar oil lab.

I do it as a matter of routine on any new-to-me vehicle on the first oil change (after I put fresh oil in, or on a new vehicle) and then again after a couple more. If everything looks ok I then check it annually.

I'm using full 5W30 synthetic. Also decided to change my oil every 3K. I know, probably overkill, but i drive relatively short distances (~12 mies each way to work) and drive the car hard. Also worth it to give the turbo some extra care. IMO.

On the TDI Jetta (turbodiesel) in my garage it now has roughly 260,000 miles on it and has had 10k OCIs since new with Rotella T6. The turbo is OEM.

There's no reason to short-cycle the oil to that degree, especially with full synthetics. unless there's a specific problem.

I had one of those until I sold it back to VW a little less than two years ago. 105K miles and it never gave me a problem other than the dreaded HPFP blowout, which VW took care of, even though the car was slightly past warranty. I almost kept it, but I felt like I was on the verge of having to put more money into it on standard aging car maintenance than I was wanting to, so I let it go. I'm not sure that was the wisest choice, but I did it, and haven't really second guessed it.

I always used the oil that VW uses, which my VW mechanic used, too. I trusted him, so I went with it. It was synthetic, but not full synthetic, I suspect.

My Mazda dealer now tells me that they DO use regular oil, not synthetic, though they'd give me synthetic if I want it. Not full synthetic, though. I'd have to supply that myself. Their claim was that synthetic was too thin since they use 0w20. Why they go against Mazda recommendation, I have no idea. They'll give me 5w30 if I want it, though. Strange. They weren't into updating the AA/CP firmware, either, unless there's a problem with what I have now. I told them about my intermittent infotainment startup failure and they said that would qualify, at least.

Is it possible for us to flash the firmware update ourselves? I can't find anything on the Mazda site where we could download it.

Mine (now my daughter's) is an '03; it has the nice reliable ALH engine with no HPFP. I wouldn't own one of the common-rail engines never mind the DPF problem (it's a wear item and expensive as blankety-blank as well)

I think you need their tool (MMDS) to flash plus you'd need the file, which you don't have. Unless there's a way to do the infotainment without it. No idea on that one.

I wouldn't even contemplate letting the stealer do oil changes if they're going to violate what's in the manual. That's just begging for trouble; you might not get it, but if you do you're in for a war on the warranty claim and there's simply no reason to take that exposure.

There's an alternative version of Mazda Connect that can be downloaded and installed. I think all you have to do is put the software on a flash drive, put the drive into the right port, and turn on the infotainment system with the engine off to flash it. So I figure the same might be doable with the factory software. But I don't see the file on their site, so they must not want us doing it. The alternative package is of an earlier vintage and probably no longer worth the bother.

I'm going to stay away from my dealer. I'll call a couple of others for further detail. If it weren't for the firmware thing, I'd just bring it to my independent mechanic, which I may end up doing, anyway.
