Hey, my name is Margaret! I don't know much about vehicles or warranties. I hope someone on here can help me with a quick question I have about Amsoil. My husband usually did this kind of stuff for me, but we have been separated for a while now. So, does anyone know if I go to this place called Amsoil, I think that's the name, will they void my warranty I already have on my vehicle? Any help would benefit me really since I’m a little lost whenever I have to go to the shop. Thanks for answering in advance!
