Going to do an oil change today, Was looking at the filters and had the tride and true AC PF1218 in my hand and then spotted the new mobil 1 filters, I've used mobil 1 10-30 since car was new so just wondering about these mobil filters, a little pricey but might be worth it as the car gets older. What are other people using? has any one used the mobil oil filter? if so how has it worked? or is it just another sales gimmick?
