Jabiru 3300 Fuel Type

I am wondering if anyone has used 91 octane, no lead, no alcohol in their Jabiru 3300 engine?  If so, any issues found, any deterioration of seals, lines, etc?  So far, I have stuck to using 100LL, but understand that auto fuel with no alcohol may be allowable?

Bob,

Thanks for the info.  Did you get a lot of sooty material?

The soot may be a result of using just 100 LL and then burning the cleaner burning 91. With an 8:1 compression ratio 91 - 93 would be fine for your engine. The alcohol type fuels seem to be the culprit when it comes to seal deterioration. Also, moving away from the lead would be a good thing. My two cents.

Chris,

Are you getting a lot of soot?  I assume you are burning 91 octane?

Thanks, Chris.  I wish we had your temperatures today, instead of 8 degrees!
