One of my older vehicles is overdue for an oil change--which is very rare with me.
But I am buying normal Valvoline this time instead of VR-1, so I need some extra ZDDP additive to help with it's tappets. However AutoZone and Oreilys don't have anything, and I'd like to get it today to do the change, and not wait for online shipping.
Anybody know local-type shops that would regularly carry this stuff?
