Review on Enhanced Filtration: PH7317 Extra 🌬️ Guard Passenger Filter for Superior Air Quality by Gregory Braddock

Fram Ultra Synthetic is an excellent filter. I sent in an oil sample from my 2006 GMC Duramax after 7200 miles and about 20 months of towing. The fine dust in the oil sample was < 0.1 percent and thus at the limit of measurement technology. Blackstone's comment, apart from being surprised at the condition of the engine as shown by the oil, was that the filter did a great job. Fram Tip: You get what you pay for, best buy Fram and get rid of the $5 junk sold by this and other manufacturers. This filter has a synthetic filter element, silicone backing and a comfortable cover. Available all day for $8 at WalMart.
