Just went to the corn juice a few days ago. Loving it so far.

For anyone on the fence, my advice...

Might be worth trying a new gasket, you only get one shot compressing them, then they just leak a few weeks later.

I'm at under a quarter tank. Really want flash Oft tune on fill up. Almost due for second oil change. First done at 1200 miles. Got then to schedule me again for 6500 miles. Feel like I already paid for the dealer oil changes do why not use then right? Maybe I can use special e85 oil in between dealer changes...

From what I understand SN rated oil is for 2011 and newer cars. This spec also covers e85?
This would mean that dealer oil is e85 safe??? I'm a few beers in so I may be misinterpreting.

According to specs SN rated oil should be E85 bio fuel compatable compatable.

I change mine to one that specificly states it is E85 compatable, just to be sure

This would lead me to believe that dealer oil is fine. I think they gave me on a 5k interval. Night be able to get away with just their oil changes. Of course I will have to fill with 93 even I take it in due to catless header(alcohol smell)

This is what worries me. I know once i try it i won't want to go back and I'll be annoyed anytime i can't fill up with E85.

Just fill up whenever you see one, I get about 450km per tank on E85 on my driving habits, hasn't been an issue in finding E85 at all and you probably have more E85 stations in Melbourne than perth.

EDIT:
Don't want to rag on it until safe.

Ok so I put some miles in it after filling up.
Then I flashed.
Then I drive light throttle about five to ten miles.
At idle STFT is at around 0. LTFT is about -2.
Guessing there is still petrol in tank....

I believe its once your lfts have settled and they are below 10 either positive or negaitive you'll be fine. It is safer when they are negative as it means you have been running rich. I wouldn't worry about the trims at idle, even on petrol mine vary wildly.

Check your Long term fuel trims over entire rpm range once its below 10 at low med and higher rpm it good to go. as per first post steady partial throttle driving speeds learning ie closed loop fueling mode.

Short term fuel trim will always vary depending on load.throttle ect.
