Try adding one or two qts of 10w40 to lower consuption.
Works on my mostly stock 90. Remember we don't need no stinking exhaust valve seals. We have a true British influenced design.
Leaks/burns oil.

Thanks Scott for the tip! I like your thought on the British influence! LOL Bravo! The way my motor behaves I almost think it likes the oil level to be at the "add" mark. The burn/use rate is waaay slower when it gets down to that point. However, I hardly ever get to 6th, and 5th rarely in normal driving unless it's early or very later and the roads are empty. JMHO, the higher the rpms, the higher the coolant temp, the higher the oil temp; the faster that hash area qt burns/is used up! I don't mind checking the oil before start up.
