Valve seals will leave a smoke trail when accelerating from a stop. You may need someone to follow you.

Tow things I'd vote for:

Stuck oil control rings. At low engine speeds, oil splash from the crankshaft is low and the rings can control the oil. At high speeds there is more splash and the oil rings can't scrape the oil off.

A clogged crankcase ventilation system. This can push oil into the intake.
