Does anyone know if pronto and premium guard oil filters are made by the same manufacturer? I have a few Pronto PO2500 filters that I was using on a friends '13 Impala with no problems, but stopped using them due to being unsure if they had the correct 22 psi bypass spec of the AcDelco PF63. Upon looking at the Premium Guard PG2500 (looks identical to the Pronto filter) on rockauto, it shows that premium guard has a bypass of 23 psi. Would it be safe to say the pronto filter also has a 23 psi bypass? I cant find any info on the pronto.
