So im planning on doing my first oil change (myself, as opposed to the mechanic). And im wondering what filter I should use...Ive narrowed it down to Fram Ultra or Purolator PureOne...I like the Fram Ultra because it has synthetic media but im afraid it has poor oil flow because of the fact that its dual layer...Im also considering Purolator PureOne...Just want to know which will have better oil flow. Im new to oil filters and oil changes. ALSO, should i use Castrol Edge, or Mobil 1. The mechanics have used edge in my car for my oil changes, but if Mobil 1 is better ill be glad to switch, i want the BEST cold/dry start/short trip protection. including the filter. please share your knowledge/recommendation. Im still a newbie to all of this =P
