Is there any reason for this in a non-flat tappet application? Do you really benefit that much from extra ZDDP if in a roller motor?
Also, thought someone once said that the regular VR1 was not to be used more than 3k OCI due to less detergents?
Just wondering the justification for ANYONE on here who may be using this VR1 oil (either dino or syn) in a street car/non-race application vs just using HDEO or HM oil instead if wanting the extra ZDDP????????????????????????????????????
