I quit using Fram years ago..... OEM filters are cheap in the grand picture of things. Those other filters may look the same but what is inside is what matters. I get my filters from Nolts Power Equipment, which has a store on Ebay.
A John Deere dealer showed my BIL the cut apart factory filter against a Fram? filter and the inside difference was remarkable. It had tighter and many more pleats in the OEM filter. That was 20 years ago so that is one way to find out.
