Hello

In one of the RX forums in my country, I 've seen a topic where it is said that doing premix is extremely important for the Series I RX-8's. I've seen it's being repeated several times in the topic that if premix is not performed on Series I, then the engine is doomed.

Is it really so important to perform premix on Series I, so much as to prevent it from being doomed?

Is premix beneficial?

The answer to that is largely a matter of opinion, as there are no hard facts about the impact premix has on engine life. My personal opinion is that premix IS beneficial to seal health, and we have some evidence that it is also beneficial to carbon caking, in that it 'softens' the carbon a bit, making it easier to remove.

However, will premixing extend engine life? If, and only if, every single other failure method is properly addressed, then yes, in my opinion premixing will extend engine life moderately. However, I expect that most premixed engines fail from some other cause well before they fail from simple seal wear, in which case premixing will not have done anything to increase the life of the engine.


The oiling that MUST be in place or the engine is doomed to an early death is the OMP system. Our engines don't last long with it removed or disabled.
