The instructions for the MW44 and MW54 call for an oil mixture of 3% for the 44 and 2.5% for the 54. That is about 1/2 quart for five gallons of Kero. Most people I know with other brands of turbines use 1 quart for 5 gallons or about 6%. Will it hurt to run either the 44 or 54 on 6%? I am afraid the extra oil might clog the needles on the fuel ring especially on the 44.

Also, are the fuel pumps matched to the engine for the MW44? If I change fuel pumps for any reason would I have to change any ECU settings?

I would ask Wren but they are at Jetpower this week and I would like to fly this weekend.

Thanks.
