Awesome thread swoope, I have been curious to know how many people have blown their motors with pre-mix.

I'm willing to say there's next to none.

The cause and effect relationship will not be established by any answers provided here.
Too many variables, not least of which is the level of mechanical empathy that a pre-mixer might possess that might otherwise be missing in other owners.

that is correct.

but, looking for a simple someone that has failed..

and i have to add na only!!

this is not a fi / tubo / sc question..

True, for the same reasons we cannot look at one or two rotary teardowns and conclude if you do X your motor will last longer or will fail sooner.

From a basic standpoint, I'd be interested for anyone who has premixed that has had a motor replaced because of a loss of compression. Sure again there are a lot of factors to contribute to seal failure, but lack of lubrication seems to have been a major reason in the past.

There's been a lot of arguments claiming that pre-mixing is just a fantasy tactic and that Mazda designed the OMP to be self contained and needing no additional service other than checking your oil.

Yep, I'd settle for any N/A motor failure where the owner premixed. I'm just curious if they are out there.

pretty sure expo premixed for the last half of his 100k engine .....

expo's engine was more a bearing issue though, and if we wanted to delve into semantics, it didn't actually fail, he decided to rebuild it early.

2 guys in the ga rx8 club have had engine replacements due to low compression and they pre mixed.

I don't believe they did so at every fill up. I premix on EVERY tank with Protek R.
