 The synthetic filters, you know, my understanding is they're trying to go for distance and mileage. But again, you know, we can have that conversation from now until next week as far as what I think about these extended oil change intervals. Because I still see that's where the problems are, even though people won't agree with me. But from the guy in the bay that sees the engine failures and sees the cost of engine repair, I still think an oil change done in a timely manner, done correctly.
