After CATERHAM brought up the subject of possible cheap 0W20 OEM oil in Canada, I emailed Hyundai Canada about using 0W20 oil in my Accent. This is their response: "In response to your inquiry, as per your Owner's Manual we recommend that you use 5W20 oil for the 1.6 GDI engine. The 0W2 [sic] oil will unfortunately void the warranty." Wow that I did not expect. Just a heads up to anyone in Canada about using that in the new Accent, as I've seen 0W20 recommendations in other Accent threads. Is Hyundai USA as stupid about this?
