Rotex 582 oil type?
Bobby Hester
I am switching to a new oil when I start flying again. Anyone flying a
Rotex 582 please let me know what you are using. Just checking to see
what everyone else is using!

I use Motul 850 racing oil. I have almost no problem with carbon
buildup using it. I also us Chevron 92 octane. THey have an
anticarbon scavengine additive that helps the stituation.
What is everybody else using???

Here in Australia, the most reliable oil has been found to be Penrite
C40 (I'm not certain about the 40) it's low carbon and has a VERY high
lubrication safety margin (for closed throttle decents).

Pennzoil----Several hundred hours and no problems. I am also a believer in
Not changing from one oil to another. I don't claim to be an expert on oils
but I've always used it and it's never ( let me down).

One customer of mine has a Rans S-12 with over 650 hours on the 582.
Burns regular Texaco gas and Pennzoil TCW-III. It's never missed a beat
and is still running strong. Compression is 135 lbs on both cylinders.
I have built a number Rans S-12 Airails all with 582's using Pennzoil
TCW-III and no engine failures todate; (knock on wood). They all have 135
deg thermostats.

I have 220 successful hours on my 582 using Castrol 2-cycle oil (the blend for
snowmobiles and chainsaws, not watercraft). It was recommended to me by Arnie
from Kodiak Research, the North American Rotax distributor. I have not had the
engine apart yet, but an inspection through the exhaust ports and plug holes
using a borescope looks good. Any carbon buildup is minimal and I have never
had a problem with plugs left in for 70 hours. For gas, I use 92 octane Mogas
(Texaco, Arco, Exxon, Shell) and an occassional dose of 100LL when going
cross-country

That's interesting. I was told NEVER to use any leaded gas in my
2-stroke by all of the race guys. Why do you use 100LL? And, any of
you other 2-stroke guys out there, what do you think about using
leaded gasoline in a 2-stroke????

Steve Beatty of Airscrew Performance uses nothing but 100LL. He claims
to have over 1,000 hours on his 447 powered Phantom and *"has never
pulled the cylinders to de-carbon."* He admits that there is carbon
build-up on top of the piston.
There is no choice but to use 100LL on cross-country trips. I notice
there is an immediate reduction in the EGT's - sometimes up to 25
degrees - after filling up. The only other difference I can see is the
brown residue on the plugs and exhaust tip. When de-carboning, I can't
determine if the carbon is from the oil, auto fuel, or 100LL. We (our
club members) have never had any problems related to the use of 100LL.
I've often wondered if the extra lubrication from the lead is worth the
higher cost.

This is one of the most interesting posts I've ever seen on the
subject. I too have always thought that 100LL would provide more
lubrication from the lead but was told to avoid it at all costs from
the 2-stroke race guys.
It would obviously run cooler because the higher octane burns slower
and cooler. I've always thought it might be a big plus for that
reason, plus the lead lubrication.
Very interesting!!!

Using 100 LL will require more frequent plug changes. I don't reccommend it
though. Flew our company plane from Fl. to Osh 2 yrs ago. 22 hrs flight time
each way. Used mostly 100 LL on the way up, and noticed a decrease in power
after reaching Osh. On the way home used only 92 auto gas, and in about 3 hrs
time power was back up to snuff. Jim

I have read that you can use 100LL but not on a regular basis. I have also used it
on cross countries when Mogas was not available. I read it either in CPS or
Ultralight Flying Mag.
Badwater Bill
That's what I thought. I don't think lead goes well with 2-strokes
from the banter I hear on behalf of the race guys.

I will choose my words more carefully next time and not mislead the group. I
do not add the 100LL to go X/C, it is just the only fuel available at some of
the stops.
