I have a 2008 Nissan Altima with the 2.5 4cyl. I drive 13 miles each way to work about 70% highway and 30% city in Florida weather. My annual mileage is 10,000-10,500 miles. I want to try a one year OCI and wanted some general advice. I am planning on using a Fram Ultra filter. M1 with the current rebate looks interesting but Mobil 1 Extended Performance doesn't seem to be that impressive over regular M1. I have had good luck with PP in my family Van and am also considering it but the claims M1 makes directly on their website about 12 months or 10,000 miles is nice to see as apposed to PP who just says stick with your manufacturer OCI (7,500). Does everyone think PP is as good or better than M1 for 12 months or 10K?
