Hey guys
Anybody that is using amsoil can you tell me what amsoil filter to use. I'm changing brand of oil from royal purple to amsoils that will save me two dollars a qt. The filter book at anderson only covered 2011 and up.

Make, model and motor of the car would be very helpful.

If its for a 2004 Pontiac GTO 5.7L look here 2004 PONTIAC GTO 5.7L 8-cyl Engine Code [F] - AMSOIL Online Product Application Guide

So sorry was not thinking it is a 2004 Bonneville GXP 4.6

Same sight just new parameters. Here you go Steve; 2004 PONTIAC BONNEVILLE 4.6L 8-cyl Engine Code [Y] - AMSOIL Online Product Application Guide

For a more direct answer the AMSoil part number is: EAO64

So sorry was not thinking it is a 2004 Bonneville GXP 4.6

Well change from Royal Purple to Amsoil and what a differance. It would knock real bad in the morning with purple in it and now nice and quiet no knock. And know for the spark plugs that'* going to be fun.
