Ahmed (aka: AMD), who holds himself out as a current Chicago-area Toyota dealer master diagnostic tech, and who hosts his "Car Care Nut" YouTube channel, definitely recommends long-term owners stay with the severe service 5K oil change intervals for the dual-injected "Dynamic Force" 2.5 liter, 4cyl. , and sticking firmly with the 0w-16 viscosity (definitely a naysayer on extended use of 0w-20 in these), though he's completely agnostic on oil brands. He's seems a little skeptical on Toyota's choice of plastic for the valve covers, which may be borne out by other posters' leak observations. FWIW, his Toyota maintenance videos are quite well done, balanced, and informative, and I see no evidence that he's merely shilling for dealer-only maintenance.
