I've been using Mobil 1 oil filters (along with Mobil 1 oil) in my 2006 Acura TL since it was new. I change oil and filter at about 7,000-7500 miles (according to the cars computer). I understand both filters use a synthetic filter material. I'm thinking of using the Pure One since they are about 1/2 the price of the Mobil 1. (My friends tell me I'm wasting money on the Mobil 1 filter at 7,000 miles.)Does the Pure One filter work as well as the Mobil 1? I'm somewhat new to all this science and value the experience of this forum. Thanks.
