Less than 300 miles. Just changed it last weekend. It didn't rupture, it just appeared that the seal was bad. Visually it looked out of round. I'm still confused as to how I put several hundred miles on it before the problem arose.
I do plan to contact Mobil 1 to see if they will do anything. At idle it was literally spraying oil out of the sealed area on top of the filter. When I say "top" I mean when looking at it from the driver's side tire, it's the side closest to the hood. It sprayed oil all over the brakes, tire, left front suspension, and driver's side of the motor.
Edit: On the subject of oil filters, isn't there somewhere to buy them in bulk? I will probably go OEM from now on.
I know Wix makes a good filter, but I was under the impression that Mobil 1 did too. I imagine this was just one of those fluke things, but it has left me feeling skiddish about using a Mobil 1 filter. I know Frams are cheap, but they've never done this kind of thing. Running a Fram on it for now.
Fram filters are fine...Been using them for over 30 years...If there were any problems with Fram filters then there would be THOUSANDS of dead vehicles every year due to the filter. When was the last time anyone ever heard of a filter killing a car?? And since Fram outsells it's next 5 competitors COMBINED.....Fram can't be making that crappy a filter.
With that said...I've been using OEM filters...My local Toyota dealer sells me a case at per filter cost the same as Fram and Wallmart.
