That's exactly what I don't understand... In the 13-16 owners manual it just says GL-3 or higher grade (something to that extent). But then in 17+ it says GL 3/4/5. But the transmissions are identical from what I can find. So they literally recommend using oil that could cause serious damage to the transmission. This is kind of why I don't think I will pursue this with them. They will probably just point to that and say GL-5 is fine to use.
