The Fram Ultra Synthetic is a superb filter. I sent in an oil sample from my 2006 GMC Duramax after 7200 miles and about 20 months, tow duty. The particulates in the oil sample were <0.1 percent and at the limit of the measuring equipment. Comment from Blackstone apart from being astonished at the condition of the motor as indicated by the oil was that the filter was doing an outstanding job. Hat tip to Fram, you get what you pay for, buy Fram top of the line and skip the $5 junk sold by this and other manufacturers. This filter has synthetic media, silicone anti drain back and easy grip cap. Sold all day long for $8 at WalMart.
