You would think so that Purolator oil filter I installed on PU started leaking within week. Leaking up to 2 qts in 20 miles at 55 mph. IT had two defects that they just covered up with heavy paint. Supposedly had a warranty against defects but they would not honor it.
I did allot of research on this and only found two oil filters other than the Toro oil filter that will not present a problem, One was an Wix filter (forget the number) and the other was a Fram XG4967 which is the premium Fram filter. I'm not a fan of the cheaper Fram filters but this is a very good filter, The Wix filter I could not find on line to order, but did order the Fram from Walmart. The problem with other filters with the same dimensions and specs is that the set-back of the mounting threads is not far enough back and my cause the seals to not properly tighten down on the oil filter mount thereby prune to causing leaks. The 708 Toro engine is made by Lucin the same company that makes some BMW motoercycle engine. Although a Chines company, they do make excellent engines for other companies to their specs including some Honda engines. The Toro 708cc engine is also the smae as the Exmark 708cc engine. The Fram XG4967 has been on my Toro now for a few months with no problem.
