| Subject: | Re: 582 oil injection |
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 dont 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. . .
