Wix 51133 oil filter for the 2001 Blue Bird Commercial Bus V8 12.1L and other vehicles and equipment passes engine oil through enhanced cellulose media to catch contaminants. This Wix oil filter is a full-flow filter in the cartridge lube metal canister style.
A low oil pressure warning light or oil seeping around the canister can mean the filter needs replacing. Before you replace it, look over the canister and base for oil with the engine off and cool, because a leak can also start at a nearby part. This engine oil filter is recommended for OEM oil and filter change intervals. The fitment calls for one filter.
The fitment covers a wide range of models and equipment. Beyond that bus, it fits the 1981 GMC Astro V8 9.3L, the 1981-1982 Astro 6-cylinder 7.0L and the 1981-1988 Astro V6 9.0L or V8 12.1L, plus the 1981-1985 GMC Brigadier V6 5.2L and the 1981-1988 Brigadier 6-cylinder 7.0L or V6 9.0L. If your truck, bus or machine is not named here, look it up on the Buyer's Guide tab.
