hi im new to this forum i have recently purchased an 2003 corolla sportivo and it has 191,000km im planning to do a full service to it so im planning to do oil, oil filter, fuel filter, spark plug, air filter and leads. Im wondering if there is anything else people recommend to do and im wondering what oils and stuff to use. i have research about what oil and people recommend 10w30 but today i went to my local auto store and they recommended for the kms i have penrite 15w60 semi synthetic so im just wondering what people recomend for them kms or it doesnt matter.
