Are ya'll sticking with synthetic oil?

[CX-SV]

Thankfully we don't have a 02 Tortoise, not that it relates to this topic, lol. Agreed, synthetic as specified in owners manual is what I use.

I plan on using only 0w-20 synthetic. I've only been able to find Mobil 1 0w-20 in stock locally. I went ahead and topped off using Mobil 1 for now, but does anyone know where to get the 0w-20 Castrol that Mazda recommends using? I've only been able to find 5w-20 Castrol. The manual states 5w-20 may be substituted, but 0w-20 is preferred.

What is the cost of the Mazda 0w20 at dealer? The Mazda synthetic is a good quality oil made by Idemitsu and might cost same as other synthetics at the local auto parts store. I've also heard good things on oil forums about the Toyota 0w20.

Here's some good discussion on Mazda 0 20 synthetic and who makes it. Seems the Mazda 0 20 is great stuff.

Looks like the price is about 8 dollars a quart. Probably retail price.

I wish Mazda spec'd a greater level of filtration. This is only conjecture on my part however have you taken a look at the filter? Its itty-bitty, teenie-weenie. Seems to me we could get more miles between an oil change with a larger filter because the one we have surely cannot hold much dirt and so it will bypass early, I'm assuming that the oils we have to use are top notch and skyactiv is not unusually harsh on the oil and so the principle reason for oil changing is to prevent operation with a bypassing filter.

I think the primary reason for relatively short oil change interval with synthetic is service department revenue stream.

Kinda off topic - But I'm wondering if I change my own for motor/tranny oil during the first 60K miles of ownership, and if i later have a powertrain related issue, will my powertrain warranty be voided because I did my own maintenance?

Downloaded the cx-5 manual PDF file. Section 6-21 lists whats recommended.
My take is that ILSAC GF-5 oils are approved but Mazda recommends OEM spec Castrol. Fortunately the OEM oil is already good stuff.


Recommended Oil
U.S.A. and CANADA
0W-20 full synthetic recommended:
Mazda Genuine Oil is used in your Mazda
vehicle and is the recommended 0W-20
lubricant. Mazda Genuine 0W-20 Oil is
required to achieve optimum fuel
economy.
Recommended viscosity: SAE 0W-20
For maintenance service, Mazda
recommends Mazda Genuine Parts and
Castrol (U.S.A. only).

Only use SAE 0W-20 oil with the
American Petroleum Institute (API)
symbol and ILSAC GF-5.Oil with this trademark symbol conforms
to the current engine and emission system
protection standards and fuel economy
requirements of the International
Lubricant Standardization and Approval
Committee (ILSAC), comprised of U.S.
and Japanese automobile manufacturers.

Its the same size and model that was in my 2003 Infiniti G35 3.5L V6 (almost twice the displacement) that did just fine...

No need to perform a full oil change if that's your concern. Simply replace the oil filter at shorter intervals and top the engine off with the same amount that was in the filter.

I agree 100%. The manual states every 7.5K, though. What will be your interval? With my Tacoma, I change it every 4.5K (as recommended) with Mobil 1. With my bikes, every 8K, also with Mobil 1. I've read that you can go as far as 15K. I was planning on sticking with the factory recommendation for the CX. BTW, is there a dummy light when you reach the recommended mileage? I have one on the Tacoma and was just wondering...

Ah, Religion, Politics and Motor Oil. 3 dangerous topics in mixed company.

It's interesting to hear all these comments on oil. I'm a member of 5 other forums, and this discussion always tends to lead to bantering back and forth. Not so much here....yet. LOL. (poke)

We don't rack up miles much. I plan on doing oil changes at every 5k miles and tire rotations at every 10k miles. Easy schedule to follow plus it takes about 6 months to get to 5k miles. Tire rotation done with every other oil change. So every year = 1 oil change, then 1 oil change plus tire rotation.

If you drive a lot of miles you could alter the format.

These days whatever the manufacter recommends for oil change intervals the general rule is to create a shorter one convenient for you. I had a BMW in which the manual recommended 15k oil change intervals. The BMW forums guys did it every 5k-7k miles. My Volkswagen CC probaly recommends 12k intervals. If Mazda does indeed say every 7.5k miles for the CX-5 I think its fine.

I will stick to 7.5K interval with recommended synthetic as long as warranty is in effect. Beyond that, still TBD but most likely same.

Isn't it 8k OR 4 months, whichever comes first?

As far as I could tell looking at manual for US owners, 7500 miles, (not that 500 miles would make any difference from a warranty or other standpoint).

 

[<se7en>]

Yup, 7.5K. Page 6-4 in our manual.

I just had my first oil change and the service adviser told me that only synthetic oil is to be used.

 

[ZuluCX]

really why bother ? they say synthetic why not put synthetic and for the price difference, I don't really see the point of this argument...oil change is $50 at the dealer all in full synthetic (just did the first 8000km one and I was surprised because it was close to a $100 on the Subaru..)

Exactly. $59 at my Mazda dealership w/synthetic. $119 at my Lexus dealership w/synthetic. (Both without tire rotations.)

If you look in the manual for the conditions that warrant the 5k interval than it pretty much covers most everyones driving habits. I don't feel like reading it again and posting it here. Just pull your dipstick out at the 5k mark and most likely it'll be very dirty. The short interval could also be because of the relatively thin 0W-20W viscosity and the 13-1 compression ratio, which will cause more blow by gas than a lesser compression ratio would and so you'll get more contaminants in the oil. Oil changes at the Mazda dealer around here cost $50. On my last oil change though they crushed the plastic panel under my CX5 with the lift. I'm pretty pissed about that.
