I have a kitfox with a 582. The builder of the airplane decided to remove the injection pump and premix 80:1 with NEO synthetic oil. The engine runs fine but I would like to go back to oil injection. Is there any way to calibrate the injection system to 80:1. Or is it best if going back to injection to switch to penziol?

Nope!!

You will get what it is geared for. about 50 to 1 WOT70 to 1 lower
settings.

No need for 80 to 1 .......... Rotax does not recomend this so why use it
?

PS - A note on synthetics in your 582 -- If you use your engine at least
weekly you might do ok . If not you will be likely to not have as good of
protection from moisture as you would have with mineral oil. that ==
bearing failures.
582 cranks asre 1200 to 1600 $ new .

I use Bombarider XPS Mineral oil and have 123 hours on current plugs in last
6 months and it still running fine.

I run my 582 on silkalene fully synthetic, with auto lube. Just coming up on 150 hours My exhaust is a bit corroded, so today I removed it for a sand blast and repaint-surprise surprise, on looking into the cylinders the engine is as clean as a whistle inside, very light coating on piston crowns and the top of combustion chamber is still shiny metal, the honing on cylinder walls is unmarked
It is true that synthetics don’t offer great corrosion protection but with frequent use that should not be a problem
I believe that marine two-stroke oils offer the best corrosion resistance, but for wear resistance and cleanliness go synthetic
On the subject of oil Injection many people have suggested I get rid and go premix!
Any Comments?

Yes , on the sythetics if you use them a few times a week on corrosion. But
if you don't you can be more likely to crank bearings life shortened.

No on Marine oil - a big no no in rotax 582 - different operating
conditions. -ie not a constant cool water supply so you need a better oil is
one reason. outboard oil is mostly rated TCW 3

I use only Bombardier XPS mineral oil in 582s. Pennzoil for air cooled is
just as good.
Rotax reco is rating of API-TC -- NOT TCW 3

Only reason that a synthetic has use to me is you will get less deposits on
your RAVE valves- if you have them , but on a 582 you don't have the exhaust
valves.

Synthetics - many will tel lyou all the wonderful things about them but what
is wrong with good mineral oil ?
I have over 300 hours in 582 in last year and no troubles with the above
mineral oil.

It's what you can't see that may need attending to. The back side of the
rings tend to gum up, reducing compression and power. Even with good quality
synthetics.

stay with the injection, you'll get much more consistent mixing. Also if
you really want to fully check the engine condition, you'll need to also
check for stuck piston rings. It usually occurs on the backside of the
pistion so you can see it by just looking into the exhaust port.

Yes. You should get rid of anything that's not single failure
tolerant. Start with the oil pump, then check out the ignition
system. It's single failure tolerant so you're OK there. How about
the cooling system. Oops, only one of those; and only one crank too.
OK, so you'll need another engine and cooling system, or else you'll
have to become a glider. Now how about those wings. Yep, you've got
two so you're OK there. You've got two horizontal stabilizers, two
elevators, but whoa, only one rudder and vertical stabilizer. Better
add one each of those, or just get rid of them, like a B-2. Same
thing for the fuselage. Got two landing gear, so you're OK there.
What about your fuel system. . .
