So today I went to the dealer for an oil change since the guy I know charges me 45 I don’t have to worry about disposal or any of that. I asked for 10w30 for the olds they usually throw mobile 1 in there then the guy says they don’t have it in a synthetic blend only full synthetic. All they have for synthetic blend would be the brand quantum I never heard of has anyone used this? Thanks in advance. From here on ima have to do it by myself
