Kawasaki FH451V -
Out: Castrol GTX 5W30 / no brand generic 49065-7010 filter
In: Havoline 10W30 / AC Delco PF1233 filter
I only ran the Castrol about 10-15 hours because of unknown prior maintenance history and I wanted to "flush" the engine out. Was going to use Rotella T 10W30 this time based on mrsilv04's experience with it in a Kawasaki engine, but didn't feel like dealing with Wal-Mart today and the parts stores didn't have Rotella T in 10W30.
By the way, for those with engines using the 49065-7010 filter, it cross references to Fram number PH4967, which is AC Delco PF1233, Motorcraft FL836 (good luck finding one at a store), and Wix 51394. These filters cost about half what a genuine Kawasaki filter costs and about half of the generic lawn mower filters too.
Also changed the oil in my 20+ year old Briggs flathead -
Out: Can't remember, but probably Castrol GTX and a top off cocktail of leftovers from the truck.
In: "Pro Select" 30 weight
I scraped the deck on this one today and it was NASTY. Lots of white fuzzy mold.
