Hi, Having a few different Prius since 2004 I'm really happy that I like my new Niro so much. I was a little worried about switching since I've had so much good luck with the Prius over the years. Has anyone else here owned a Prius and what differences do you find? My last Prius started using a little oil after passing the 160k mi. mark. I'm thinking that using 0w-20 oil is too thin for a small 4cyl. car especially in the heat. I see the Niro has a choice and I'm thinking of using 5w-30 oil does anyone else use that weight oil? Thanks!
