Hey everyone, I have been on a search for this oil and my Canadian dealership doesn't have it and uses Petro Canada 0w20 oil which I don't know allot about and will be getting a used oil sample from my CX 30 and sending it to be tested so I know the Tbn etc during the maintenance schedule to see how well it's holding up. Yah you could say I'm obsessed with vehicle maintenance and such but I really want to use this oil as it's in the owners manual.

Okay. The company Idemitsu that manufactures the Mazda oil no longer makes the moly GF 5 version. They have moved on to a GF 6 0w-20 without Moly. If you are willing to spend 70 US you can find an oil change kit on Amazon.

Only 18 kits left... I have used there kit 3 times now and its perfect.

Thank you for replying with the great info , I'm not so sold on the Petro Canada stuff my dealership uses and so since Castrol is listed as well in the owners manual I picked some 0w20 Castrol up for now .

I am thinking on my next oil change of using 0w 20 Liqui Moly... I do notice a notable smoother idle with the Mazda oil. I used Castrol 0w 20 on my first change. Changed it after 5,000 miles and it was much smoother. Not just a placebo.. I was not expecting any change what so ever.

Your car is a lease so I would not worry about what oil you use. That is unless you plan to buy out the lease. But I know you are waiting to upgrade to the Turbo...

Good to know Castrol runs better..yah I know I shouldn't worry about it but I want to get the most out of the engine with max fuel mileage and that's why I want to use what they recommend and not use whatever the Petro Canada stuff is the dealership uses and me being obsessed with vehicle maintenance lol . I for sure will upgrading to the turbo and night keep that one and will but my own oil again for the dealership to use as I'm not confident in the Petro Canada synthetic stuff. Thx so much for the info tho 😃 very helpful!

I found it !! I called this dealership Mazda Synthetic Engine Oil (0W20) which is not that far away and I called them and spoke to a parts guy and he was baffled as to why my dealership is useing a aftermarket oil and they do in fact carry the Genuine Mazda 0w20 Oil and i can order it from them and so I am going to! They are not to far away from me so shipping shouldn't cost me to much. check it out @asdowntown

I'm curious. Why would you use oil with moly, beyond the initial break in period?

The oil linked is not the same as the one in the OP; Mazda Synthetic Engine Oil (0W20)
Hmm and well I want to use it because of its high firction reduction properties as I tent to be a bit of a spirited driver keep in mind and as well not having a block heater in temps as low as -38 below Zero. Also the moly aids in better fuel economy and overall I mean that's what th engine was meant to use that's all 😃 also a little obsessed with vehicle maintenance 😜. Iv worked behind that's service counter and worked in parts department and I am very detailed focused.

This is the oil Mazda recommends in their Skyactive engines. Correct that is not the Molly version. Double check Detailcarguy
I thought that it was not the molly version.. tho Now i am curious to know who makes this 0w20 mazda oil? Tho not molly curious to know who makes it? In months to come I guess i could say I am using this cx-30 as a test point as its leased and will be collecting used oil samples and seeing the TBN etc... I am going to run the current oil in it that my dealership used which is the petro canada 0w20 synthetic and after Will be trying the castrol Edge that i got on sale from work and finally the mazda 0w20 and will compare test results all following the maintenance monitor on automatic as per dealership set @asdowntown I guess you could say I have a curiosity and so will let lab tests show how much each oil deteriorates.
This way If i plan to keep my next cx-30 being the turbo.. I will know which 3 oils is good to use .

Just came across this thread. I do an oil class for professional technicians to help them keep pace with the changes in engine oil technology, it's an eight hour class and that isn't enough time to tell them everything they need to know.

The first thing to know about engine oil in North America is the word "Synthetic" on the bottle doesn't mean it's a true synthetic that you would find in other parts of the world, especially Europe. One of the responses mentioned Castrol. Look on the bottle, towards the bottom (could be on the back) and see if it says "Not for sale outside of the Americas" or something like that. Now ask yourself just what does that really mean? (It doesn't mean anything bad but it is important)

In North America a product that uses a base stock made from Group III plus conventional motor oil that has had some additional processing can be called a Synthetic. In Europe only a product that is a Group IV (POE) Group V (ester) and Group VI (PIO) can be labeled synthetics. A synthetic blend can be even more difficult to judge because a product could be a Group II base stock with a little Group III, IV, or V added to it and really be inferior to the Group III Plus.

For now the easiest way to choose the best product for our Mazda's is to look for GM's dexos1 Gen2 approval on the front of the bottle, the brand name of the oil isn't important. To get that approval label the oil had to be sent in to GM and be tested. I could go into the ACEA ratings if you want to try and find the absolute best products out there, but an A1/B1 is sufficient, especially if it is dexos1 Gen2 approved. You will also notice that any product that is approved for GM's spec will also be an SN+ and GF6A

I've only looked into this in a minor way. Seems I saw something saying there is a "Mazda oil" used at the dealers for oil changes. Anyone know about this?

Most of the Dealers here in ontario canda use a bulk synthetic oil from petro canda.. which I am not sure I like so much and i think somthing like castrol synthetic oil would hold up better in regards to following the oil life monitor.. I am curous to see how well this oil from petro canada really is because its a not exspensive stuff...

The second link in my last post was a list of all of the companies who have a licensed dexos1 Gen 2 product and the viscosity. Here is the Petro Canada product that is on the list. The Petro Merica is the same company for outside of Canada. Remember if it is dexos 1 Gen2 approved it meets Mazda's requirements easily.

So I take the it is a good oil... say as good as castrol full synthetic? Keep in mind I am a pretty spirited driver and so I want a very durable oil.

In short, yes if it is on that list then it is an excellent choice for your car.

Here is where some of the confusion starts. These four products are all great, but one of the oils in this next picture does NOT meet the specs for Mazda. That doesn't make it a bad product, in fact it is a very good product, for the engines that it is designed for. So all four of these are excellent choices for the vehicles they are approved for and a poor choice for ones that they are not. The GM dexos license actually helps to make it easier to understand the differences.

So you can't just go by brand name, you need to understand the specifications that the product is approved for. Here are all of the Castrol dexos1 Gen2 approved products.
