My mower takes 56 ounces of oil with the standard filter...
With the oversized STP S3600 (Fram 3600),
it takes 8 ounces more, 64 exactly.
Two quarts, one 10W-30, one 5W-30, NAPA full synthetic...
The majority of Kohler and Briggs filters are e-cores,
You can put a nice NAPA Gold, Wix, Fram Ultra, Purolator PureOne or Synthetic
on for the same price...
