Filter Media and Service Details

This WIX cartridge oil filter uses cellulose media to help trap wear particles and other contaminants before they circulate through the engine. The 20 micron rating and cartridge lube metal canister style make it a practical choice for Mercedes-Benz engines that require a precise OE-style filter element. The WIX 51246 is referenced for OEM oil and filter change intervals, typically 3,750 to 10,000 miles, with service not to exceed 12 months.

This part cross-references ACDelco PF2145 and FRAM CH6847 for the same application.
