i think we need to get clarification on oil change intervals, and type. i know this has already been discussed, but there seems to be different answers depending on what dealer i spoke to. this applies to 1.6t engine. 2020 handbook says oci 6k. 2021 says 8k. when i called the dealers back in 2020, both said cars come with syn blend, and that is what they put back in. now, one dealer says the same thing, another dealer says there was a bulletin back in march(when we got our car) that put the intervals back to 6k for all years, and full synthetic. he also said what they put in is 5w-30. the other dealer, where we got the car, is smaller. the tech/adviser i spoke to said they have not yet serviced any 2021(or maybe he said any 1.6t) cars, and he would check with his tech. while i dont care for the dealer that told me full synthetic, 5w-30, i would take my car there for the free service, otherwise, i just take it to a local independent. which i have already done, twice. of course, calling hyundai customer service does nothing, all they say is ask my local dealer. when i tell them what the 2 dealers said, all i get is , "huh?" so, if anyone else calls their dealer, post back here what is said.
