Got 25 hrs of use on my new lycoming 390
On my rv-14a. Using approximately a quart every 4 hours. What do you mechanics think?

Keeping it around 7 quarts.

I went through the same worries and similar high oil burns on my 390 <50 hours. Borescoped, contacted Lycoming and all told me to keep running hard on mineral oil. I did until 75 hours and it got down to a qt every 6 hours or so, then switch to Phillips. By 100 hours it had dropped dramatically. At 250 hours I am burning hardly any oil at all, less than a qt every 10+ hours. Borescope looks ok to me.
