I have been using Mobil 1, not sure if it is advance fuel economy or not, and to be honest I have used Fram (yes, I know I will likely get flack) synthetic oil filter. I think it is the mid grade one. you got a pick of the reg, mid grade and top of the line Fram. I once bought the Mobil 1 filter because it was on sale. I have switched to Mobil 1 only 3 oil changes ago. Prior to the switch I used several high end brands of oil and I have had no issues, always change it at 8000kms intervals. I have used Mobil 1 many years ago in another country and car and I do like the brand, the reason I switch back was only because I have a Walmart discount and I price match the oil when it is on sale. Typically it is nearly CAD$60 and when it goes on sale it drops to mid $30's and then I get the discount. Mobil 1 typically was always $15 to $20 more than the other high end brands but I have noticed (at least here in Canada) the they all seem to be withing $5 of each other now.
