 I don't see the value or the point of synthetic filters, not unless we're going super long distance. I think it's more important to use a good quality oil, obviously, that meets manufacturer spec and change that on a regular basis. I think a good filter that's meeting manufacturer spec, the synthetic filters, my understanding is they're trying to go for distance and mileage. But again, we can have that conversation from now until next week as far as what I think about these extended oil change intervals.
