Amazon offers Prime members the
Mobil 1 M1-110 Extended Performance Oil Filter for
$7.99 with
free shipping. (Non-members can get free shipping via Subscribe & Save, but be sure to cancel once your order ships to avoid being billed for later shipments.) That's $1 less than our May mention and $7 below what you'd pay at a local auto parts store. It holds up to twice the amount of contaminants as other filters and prevents dry-starts.
