Not sure what you're trying to prove. It seems like your "master tech" is rather misinformed. My S2000's redlined not at 8400 rpms, but at 9000 rpms and they would consume less than a quart of oil every 3000 miles.
If burning a quart of oil every 2-3 tanks of gas (700-900 miles) was acceptable, gas stations would already have oil pumps next to their gas pumps
If your M3 is consuming a quart of oil every 700-800 miles, take it back, because it is defective.
