If the Delco PF454CL was the original filter for the 230 it does have an ADV. Summit racing lists both ADV and non ADV filters for the 230. Rockauto lists filters only with ADV. From now on my 250 gets only ADV whether it needs it or not. I think it is good insurance to keep those bearings lubricated on start up.
