Mobil 1 EP..It's usually $1.00 cheaper than Bosch. Called the Tech Rep at mobil and they said it won't have any problems at 15,000 miles and claim it catches up to 10 micron in size particles, no other filter on the market has made that claim. At 7,500 miles I would use a Fram Xguard rated at 10,000 miles. I know people hate Fram on this site, but most won't argue with how well that filter is built. I use the Mobil 1 EP because I run nearly 10,000 miles so I wanted more wiggle room than Fram gave me. I tore that filter apart numerous times( Fram XGuard), I'm very impressed with the Media and the constructions.
