The car dealership told me that the Sonic uses a special kind of oil and that it can only be changed at the dealership. Is this true? I can't just use regular oil?
Technically you can use whatever 5w-30 oil you want. But to keep the warranty, it must have the Dexos certification. Off the top of my head, I know that Castrol Edge has it and Mobil 1 most likely will too.
Kind of annoying though, I have a 4L jug of Castrol Syntec left over from my previous car that doesn't have the certification. But whatever, I'll use it for top ups if I ever need them.
