Hello to whoever reads this not. I will like express a little discontent about how Mazda kept quiet that is you add 8 oz of 2 cycle oil to a full tank of gas, this will eliminate a lot of problems with the loosing power at high rpm, or any rpm for that matter. After uncounted hours of searching and money spent on unnecessary sensors found out through sources that the problem is that not enough oil goes into the rotary engine, in order to prevent high emissions, affecting engine performance and, who knows…engine replacement?! If you have not tried adding the oil to your fuel tank, please give it a try. My car is working at a very different standards thanks to this, so forth Lucas 2 cycle oil gas done the trick. Mazda should have at least recognize the issue…

Hi Jose,
while I understand the frustration do know that Mazda worked on this a LOT after the Series 1 vehicle came out and it was addressed through countless PCM reflashes that were adjusting the Oil Metering Pump. Instead of having the end user add 2 stroke oil per tank, Mazda was increasing the OMP settings to assist with this.
Series 2 motors addressed this issue as well.

At the end of the day, yes pre-mixing is viewed as a good thing for most Rotary vehicles.

This is way oversimplified.
Premixing has been around for as long as there have been engines. If adding oil improved your engine`s performance then its masking the issue and not fixing it. Extra oil provides better sealing on otherwise worn seals. Preventing wear is a different story. While premix is cheap enough to use even if it does nothing, whether it actually helps prevent engine wear remains to be proven conclusively.

As for searching and replacing sensors needlessly, that sounds like a failure to properly diagnose the issue. What symptoms were you actually experiencing? What service was carred out?

I appreciate everyone opinion about this premix oil, honestly I spoke to anyone in my area and looked in this forum for answers about the lost of power at load and no one had a single clue on what was possible wrong with the engine. And as I mentioned, by adding 2cycle oil, the issue disappeared and working better. Thank you.

Well, I guess I'm going to break this down a bit to dispel some misinformation..

False.. Mazda kept quiet about nothing. Premixing oil into your fuel tank has been a standard practice for a long time. Mazda doesn't provide the consumer with this instruction as the vehicle is produced with specific emissions output parameters and a catalyst to match. This is very strictly regulated around the globe, and by adding a 2-cycle oil into the tank, you are having an effect on the emissions output of the vehicle. Different 2-cycle oils have different properties as well, so each one will change the emissions output in a different way. This makes it nearly impossible to know what the emissions output of the vehicle is and what effects these added compounds would have on the catalyst. Mazda uses the EMOP (electronic meter oil pump) to inject a calculated amount of oil from the sump into the combustion chamber as outlined in the onboard programming. This way, they have much better control of the vehicle emissions.

Loss of power is a result of a number of other causes ranging from worn out ignition system components, to a failed catalyst, dirty or damaged intake or exhaust sensors, low compression, a combination of those items or others just to list a few off.

Very necessary I'm sure.

What sources? How much oil is enough eventually becomes a subjective debate. Is emissions a factor? Yes it is. Is the average owner who may not check their oil level regularly also a factor? Absolutely. Is the engine optimized for performance from the factory? Many would argue yes as even with an excessive number of bolt on aftermarket modifications and removing the catalytic from the exhaust stream, tuners are only able to achieve around a 10% increase in power over factory output. That said, most factors that are negatively impacting engine performance are a result of the items I mentioned above, not the oil metering system. Additionally, some of those other systems I mentioned being worn or failing could be the leading causes of engine failure before the oil metering system.

I highly doubt your car is working very differently just by adding 2-stroke oil into your fuel tank. I'm willing to bet that you either believe it is working better when in reality it isn't, a replaced component resolved your issue, or you are having an intermittent issue that will rear its head once again and you just believe it to be fixed as it went away around the same time you began premixing.

it’s a lack of understanding, not communication

your’s and not Mazda’s, to be exact.
