RE: Norvel Engine FAQ
Tsutomu,
Normally, car fuel has only 10 to 12% synthetic oil. There are complex reasons for this, mostly that cars rarely go to full throttle for more than short periods as in 30 seconds or so, on the straight away. Then they throttle back for the turns and need small oil for instant throttle/acceleration. Boats, however, may need much oil because they do run full speed for much longer straightaways. I am not really sure, though, how much oil is best for boats.
I would suggest that for airplane engines, too much oil would not hurt performance too much. Especially because you have lots of nitro. Perhaps you should just try the fuel and let us all know how it performed. If you have a tachometer, we would be interested to know maximum RPM, idle RPM and how well the throttle response works.
