I've seen this question asked in many forums as well. I don't feel it hurts to answer a legitimate question from someone who is asking for clarification. Aren't these forums here to help people?

 

Without starting an argument it may only be that he was express his thought....
If you type into a search engine the question...**"what engine oil should I use in my car" you can see perhaps the frustration in answering the question??? LOL
And as I pointed out alone with many opinion vary and most are not empirically based.
Lastly I look personally look at some questions on forums that has answers a bit a laziness on the part of some OPS not to use the search feature first to see if the answers to questions (basic unchanging over years) can be found?
**About 799,000,000 results

 

Im well aware it takes 0w-20 and the size/model of the filter. was just wondering the brands people use in case some may be superior to others or 8f they had negative experiences with certain ones. Thanks to everyone for their inputs.

 

Yup that is what the oil cap is labeled with hehehehe! ...... mine no longer does I painted the cap!! As for me I use the velocity choice based on the driving and the environment the engine will be operated in between oil changes . Most of the time I would say 0w20 but this mathematically does not always work out to be the best choice.
If anyone posted having negative experience with a manufactured direct applicated oil filter it was the installer problem
As for oil...only a few of us actauly take the time to have some fluid samples sent in and analyzed . So again many opinion responses would be highly suspect and more less then accurate and not even a smedge close to anything of empirical information.

Well changing your own oil isn't going to void your warranty. However if you fail to properly tighten your oil filter than clearly you will lose the warranty. Aside from any thing like that you shouldn't have to worry about

 

 

I just wanted to throw something out there for the protection of the people changing their own oil. When others say it must meet specifications required of Mazda don't misinterpret that as simply the same weight of the oil that would be a very bad mistake if down the road, you did have to file an engine warranty claim. Because remember ignorance is not an excuse... I've done my own oil changes on every motorcycle and car that I have owned. Now with my Mazda I'm going to have the dealership do it only because they provide lifetime free oil changes so that's a no-brainer for me. Plus I have a 7 year 75000 mile warranty on the vehicle so that's also les stress if there was an issue.

and let's be honest about something else as well. Just because you have the receipts to the oil changes you provided doesn't provide them with the concrete evidence that you know what you're doing. Example, A friend of work a couple years ago almost lost the engine in his Chevy pickup truck. Why?! Because when he changed the oil filter he failed to notice the previous oil filter left the little rubber or silicone ring behind.! So when he put the new oil filter on top of it it provided a double gasket and therefore the oil pressure blew through the gasket as he was traveling down Interstate 70 in Pennsylvania.... my point is, did he use the right oil? Absolutely! Did he use the right oil filter? Absolutely! But did he know what he was doing? Not really! So if his engine would have seized up and he would have had the vehicle towed to the GM dealership where he got it from. And a particular circumstance, what do you think the outcome of the warranty would have been... (Drum roll please)

so I guess my other question is how often would you be requiring an oil change based on your driving? If you're a person that only needs one oil change a year and you're doubting your abilities, or if you even have to question how to do it. Thst Might be the answer you should be listening to.... step back and possibly let somebody else be liable for your vehicle if it is under warranty...

also with that being said Mazda uses oil that is rich in molybdenum. That is a specification that they require must be met in order to maintain and keep your engine powertrain warranty... going out to the local store and trusting Billy Bob at the counter knows anything at all about Mazda specifications is a tremendous risk. And just getting the same engine oil viscosity ( weight)is NOT the same thing as meeting Mazda specifications... just saying

 

USA: A independent auto service shop or center warranty coverage associated with the auto manufacture is exactly the same with the auto manufacture if one does there own basic service like oil a and filter changes. Even when a dealer performs service work human error is always a factor and consideration but demonstrating the correct parts is mostly all that is needed.
As for the MAZDA oil recommendation...it is nothing more then or special when you read the basic minimum requirements. Keep in mind that MAZDA changes what oil they have used largely which oil supplier met the bean counter limits and nothing to do with who the supplier of the oil was. That is why looking into what MAZDA used over decades changed and repeated based on the dollar value and not the quality or any "special" for MAZDA only engines!

You can read all about who ,what and where, under this protection ACT below. If anyone has question regarding this information the best thing to do is call a MAZDA Service Adviser and talk with them. Mention this ACT at the beginning of the conversation so you get accurate information.
https://en.wikipedia.org/wiki/Magnus...s_Warranty_Act

 

I totally agree human Error can result anywhere. . The one thing nice about the human are happening at a shop is the liability of the situation verses doing it yourself if you're not skillful enough and then having a liability Falls solely on your shoulders. .

When I first got my Mazda just under 3 months ago and I was at the dealership parts counter, getting mud floor mats, I saw a quart of their oil. The Mazda oil and I noticed that they emphasize the word Moly.. so I then went on to a very trustworthy oil form Bob is the oil guy. Calm and there's people who literally will spend the money to buy a quart of oil send an unused sample out to be tested. So I researched who has done. And I wanted to see what was so special about their oil and here they do have a significant amount of MOLY in their oil versus other oils.. so I knew at that moment that this was more than just marketing hype. And I knew how easily somebody can go out and buy whatever oil they want and it may be a fantastic oil but does it necessarily meet the manufacturer's technical specifications that's the critical bit of information in a warranty claim.. I've had friends who have tried to file warranty claims for either engine or transmission related situations. And they're sloppiness would lack of following simple directions from the manufacturer resulted in substantial Financial penalties... (Voided warranty)

Another thing I noticed a lot of people do is their misinterpretation of that magnus act.... the original purpose of this act was to prevent dealerships from forcing you to get your oil changes done forcing you to use their air filters and stuff like that .. and the only way they can force you, because there is actually a part of the ruling where they can "force"you , is they can force you to follow their recommendations and you not have an issue filing a warranty claim.. IF they provide this service for free .. the original intent of this law ways to prevent dealerships from completely taking advantage of their customers by using fear tactics..
I remember on a lot of the other forums I belonged to over the many years.. people thought this magnus-act was basically a get-out-of-jail-free card, meaning you can do whatever you want however you want and they can't void your warranty and then of course after a couple years you start reading about the same people crying because they were denied...

and essentially it's referring to maintenance related items. And meaning as long as what you do is in line with their guidelines you don't have to buy their product that's essentially it. It doesn't mean you can strap on turbo and nitrous and they can't void your warranty when your engine explodes on your way to the grocery store.. lol

On one of my forums that's motorcycle related there was a guy who was using 5w 40 weight oil because he claimed the 40 weight was all that was important well of course his engine goes and they voided his warranty ... he claims he was going to hire a lawyer because he knows how this law protects him meanwhile no lawyer took his case. So in his infinite knowledge and MORE IMPORTANTLY is interpretation of technical specifications. He thought he was doing his motorcycle a favor by using 5w40 thinking it will flow faster meanwhile he never understood the number before the W in relationship to oil ... which is the actual viscosity of the oil until it reaches operating temperature so he was using a viscosity four times thinner than the recommendations of the manufacturer and he wondered why they avoided his warranty.... Lol ...

Sorry for being so long-winded but through my experience of motorcycle forums in car forums I've read so many complaints about voided warranties and in every single one of the situations it was the customers fault for their inability to fully understand the technical specifications or what that Magnus act actually meant....

 

I knew when I responded in this thread it may go a little arm chair expect responses to have to redirect and support my responses a bit more?
I was a Suzuki Technician for a few years so the information about a warranty claim on the last response....Well lets say I would like to have read the complete complaint and response from the manufactures warranty claim department. Second hand info is worth nothing. While I like the posting about bikes the choice of viscosity is first should be a consideration what is recommended and then other considerations mostly the operating environment of the engine to choose the "BEST" viscosity oil to use. Keeping in mind to make sure that the basic requirement are met for choice of oil like SAE rating of the oil or other ratings.
As for the Magnuson ACT I am very familiar with it from beginning to end all the updates and many followed posting of its use since its enactment years ago.Counterman magazine has had many articles of it use to help educate parts store and service technician in the USA.
Last and read this carefully.... I have current oil analysis of MAZDA oil used in my new 20118 Mazda 3, 2015, NO the MAZDA oil is not any better or has more of anything then many other available motor oils. A little research may lead a few curious to find that there are not as many different oils , but lots of marketers of motor oils..
I have had oil samples analyzed for years .
Learn and lead by example and acquire real knowledge... have your oil test and analyzed .
