So, before you start using pre-mix on your Renesis, please think twice!! It costed me close to $500 to replace the pump assembly.

Pre-mix has no appreciable effect on your fuel pump. If anything, it will increase its lifespan.
The problem is the crappy Arram pump unit Mazda used in the fuel pump assembly.
