pre mix

[RETed]

As long as it carries the TC-W3 certification, you should be fine.
The TC-W3 certification has standards for performance, and flowing through fuel injectors should not be a problem.

As for no lubrication on decel...
There are some tidbit in the above link.
Internal lubrication is a combustion by-product of the pre-mix burning.
Unless you're doing some really extended decel periods, it's not a concern.
Remember, the winning 4-rotor 787B @ LeMans ran pre-mix with decel fuel-cut off (this is primarily for fuel economy); internal engine wear was not a problem.
This has all been documented in tech papers - i.e. SAE papers, etc.
If it really matters, it was running Idemitsu pre-mix.
