Caterpillar engine oil filters. We list four: 1R-1807, 1R-1808 (Advanced Efficiency spin-on, sold singly or as a case of 12) and 1R-0716.
The quickest way to the right filter is the number printed on the filter you are replacing, or your engine serial number checked against Caterpillar service information, because the same engine model can take different filters depending on serial range and application. If you want an alternative brand, many CAT numbers appear in our Fleetguard cross reference with the Fleetguard equivalent we carry.
CAT fuel filters and fuel water separators (1R-0749, 1R-0750, 1R-0751, 1R-1804, 175-2949 and others) are in CAT fuel filters, and every Caterpillar part we list is in the CAT collection. Oil filters from other brands are in oil filters.
