Hello, We have a zero-turn radius mower bought new,a John Deere 737 Ztrak. The OEM oil is JD 15W40 or SAE 15W40 and the filter is AM131054. The price on this filter quoted at $17.99. I want to make sure I have no trouble with this machine. Any recommendation you can make I appreciate. I can get a WIX cross-ref 57103 for $8.50 at local auto parts store and their Co. brand of SAE 15W40 for about $14 a gallon. Any better ideas? Thank you for your input!
