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?

John,

Thanks for the information and the clarification on the rivet line.  I built my deflector for the heater and am waiting for the weather to go above 8 degrees to install and test it.  I flew the other day and had great heat on the passenger side, but cool on mine.  The deflector should help a bit.

A new fuel tank would be a good idea, but I'm trying to convince my children's mother that I need a paint job, she'd have a real fit if I start building tank trailers!  I'm taking her to Ireland in April, nothing like bribery!

Darn it, Ed! Now you've spilled the true secret to successful homebuilding ... bribing the spouse!

Minus 5 degrees here today, so I'm working inside!!  Headed to Fla. and SC soon!

Bob,

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

Ed

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?

Ed

Not getting any.

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

I have to admit we have some nice weather right now.

Enjoy it!  We are headed south in about a week.
