Hi!!

I know that you recommand to use Mobil oil synthetic
but in my area I can't find it, is the Motul semi-synthetic is a good
choice??

thank!!

use motul 800 at:
Motul 800 RR racing synth 3-4%
Motul 800 OR offroad synth 2%

Hi Pe!!

I fanally found the motul oil, I bought the offroad
You said with Motul 800 OR offroad synth 2%
on the bottle 2% = 50:1, evolution recommand 40:1

Do I'll go with 50 or 40:1

thank!

for the 58cc, use 3% for the first tankfuls, then taper down to 2% as the engine runs in.

thank!!

Hi Pe!

I flew my plane a lot last week, with the motul rr at 40:1
I noticed that under the fuse there is a lot of black risidue
Is it the oil that making this or because the motor is too rich
Evolution recommend to put HS at 1 3/4 mine is just a little bit richer like "1 13/16"
the motor is running great with this setting

thank!!

That is what gas engines do when new.
As the engine runs in, the black will get a lighter shade, and finally goes away nearly completely.

Thank!!
