I have never been a synth user to any extent,but i am giving serious thought to doing a 1yr or 10k oc in my GMQ to see how it works for me.I need a filter to go the distance.I normally use the MC FL820S or the P1 equivalent(can't quote the number off top of my head).I will be using Amsoil,most likely the XL series 5-20,should i use the Amsoil EAO filter or would the MC or P1 do the job just as well? I'm thinking they would!Opinions please.
