I have a 06 chevy silverado 4.8 v8 and have been using purolator pl 14006 premium filter and i have also used the mobil 1 both came back with good uoa's. But i'm looking for a larger filter with more capacity.Does anyone know of any? I've asked the dealer and several parts stores with no success.i figure it will be something taller/longer since there's hardly ant clearance between the oil pan and filter.
