First time I ran my benzin (idling for the 1st tank)
there was black oil deposit on the ground coming from the exhaust.
Is that normal. I know a nitro is usually a clear oil deposit.

I'm using Maxima Castro 927 Oil. I'm using a ratio 3oz oil to a gallon of regular unleaded gas (1:40). Both needles are at 1-3/8.

Thanks

I consider that normal on new engines, as the engine begins to polish itself to the broken in state, and mettalic dust, immersed in oil, comes out of the exhaust like that. After a gallon of fuel or so, I generally see the symptom go away.

I cannot comment on your oil choice, never tried it.

Mine was dark as well for the first few tank and as I burned more fuel it lightened up.

Interesting oil choice, never seen it.

I found this oil from a writeup by James Wang of Rotary about Vario Benzin,and a place close to my work sold them. This is my first Gas Heli, and I'm loving it. Might not be the last either. Thanks for the response.
