hi new member here ive been reading here for a while now and im getting a lot of great info.last week i found GC in kalamazoo mi so i had to buy it.ive been running penzoil 10-30 with no engine noise but with GC ive got a ticking noise at start up that goes away about 2 minutes after started. should i drain or keep running.its a 4.7 with recommended oil of 5-30
