Hi,
As my 2017 Elantra approaches 40K, and since I plan on getting it 10+ years (I drive about 12K a year), I am looking at doing a automatic transmission fluid change shortly. I know it has been said in some forums over the years that you MUST use genuine Hyundai SP4-M, otherwise you will void the warranty. Is that STILL the case for the 2017-2020 Elantra models? Any real benefits to use Amsoil over Hyundai OEM SP4-M, or is Amsoil mainly marketing hype?
Thanks
