Hello everyone, I have a question, it seems to be silly, but it is important to me , my mother has a Kia sportage 2016 with 2.0 engine , she asked me to change the car oil , after six months after last oil change, she insisted on that as the car owner manual recommended ( 6000 km/ six months), for me this is absurd, because she drove it only 1650 km and the engine time monitor indicates only 75 operating hours, the dipstick oil appears fine brownish oil , not new , but not black either, the car has Amsoil OE 5w30, I want to extend the oil interval to one year as she drives the car lass than 3000 km every year, is it ok to let the oil inside the engine for another six months in term of Amsoil OE oil ability and term of the engine safety, thank you in advance .
