Review on ACDelco PF2129G Professional Engine Filter by Cody Siger

I have been in the automotive industry for many years and one thing I can tell you is when an engine goes out of construction and Of course, if you want to claim warranty service, you must prove that you have met the minimum requirements for the service. When my car had an engine problem with a Delco AC filter there could be no fault that it was properly serviced. Of course they would have to prove that the aftermarket filter was the reason for the warranty denial, but it's easier to just use parts that are unquestioned. You CAN change the oil yourself and keep your warranty – just keep your filter and oil receipts as proof. There may be better "high efficiency" filters out there, but if you change them often enough, there's no need to. think it will make a difference. I take good care of my car and change the oil and filters regularly as cheap insurance and also do an oil analysis to confirm this.
