Most likely you changed your oil always a little too late and have clogged up the piston ring's oil flow channel. Thus, your piston rings are fried. Most likely a top overhaul to replace new piston rings and seals are needed.
Toyota engines are prone to this issue. Change your oil early and don't stick to the 10k km for FS.
