They kill me with the marketing on oil filters. ALL filters can use synthetic or conventional or anything in between.. the only thing that matters are change intervals. If a filter is good for 3000 miles, it's good for 3000 miles. If a filter is good for 10k miles, it's good for 10k miles PERIOD. I get the concept of using a filter good for 3k miles with an oil that's going to last 7.5k miles may be illogical....for many....but there are still people who change full synthetic oil every 3k miles which is their prerogative. For that it's just as illogical to buy a 10k mile filter to use 3k miles because the 3k mile filter is marketed for "conventional only" oil.
