Hey guys I have 78k on my g. (00) I have been looking into the Valvoline's SynPower full synthetic. I think it is new or something.. well I am not familiar with synthetic oil. I need help with the right weight of the oil (10w-30) or if there is any other better brand? The filter is the same right? and I think it last twice or about 5k per oil change. please anyone help me with this. Thanks.
