Here's my list of filters etc,forbthe GC1715
My personal preferences Diesel engine oil is a Mobil 5w-40 full synthetic because it is highly rated and yet it's both available at many outlets and is often on sale and rebate. Comes in gallon jugs as well as 5 gallon pails. (no, it's not the Delvac 1300).
But She'll makes a good product as well.

I'm sure numerous other options for fuel filters are available. However, the hydro filter seems to be a more unique choice.
