Please advise as to the best fuel to run in this engine. I have loads of magnum 20% and am told that the engine need 30% heli fuel

Thanks

Coolpower 30% heli if you can get some.

30% fuel is had to find right now. I run my 140 and 160DZ engines on 20% fuel made with the lo-vis Klotz oil and they run very well. If you ever let them see even one tank full of 30% they remember and you can't get them to accept 20% anymore so I won't use the 30%.

They will run fine on 20%. Just down on power a little. They definitely run better with 30%. PowerMaster still has 30% fuel currently.
