Hello,
If you look up the oil filter for a 1966 to 1978 Toro, it will come back with a Delco PF -24 which is the same as the old Purolator filter number PER-33. The PER-33 / PF-24 is a shorter (less volume) version of the old PER-5. I like the 5 better than the 33 simply because it is a bigger filter with more filtering area plus it allows the engine to carry more oil in the system. Besides being better for cooling the oil, that extra 1/2 quart of oil can come in handy if you have a leaking or burning issue or if you use an additive. I don't think that they make a new version of the PER-5, but I just bought a bunch of the 5s off eBay for cheap. The threads are the same 13/16 and the rubber gasket diameter is the same, only the height is different, the PER-5 is about 50% again longer than the PER-33 or Delco PF-24.

I've noticed that trend in other oil filters lately. The Ford FL1-A has been used on virtually every American made Ford engine from 1956 to the 2000s. It's a big, full quart filter.
Little pint filters are being substituted at oil change shops. When you look up the application for the puny filter, itlists the vehicles that used to use the full size FL1-A.
It's a freaking rip off.
I have a supply of Hastings filters for the Toro which are full quart size. Maybe I should stock up on a few more.

Just another reason you should do your own work. Bruce Roe

I first noticed this when I looked under the hood of my business partner's '93 F-150. It had this miniature filter on it and I was certain the shop had screwed up. I looked up the part number and it was listed as correct for a bunch of little 4 and 6 cylinder Fords and other small cars.
I told her to take it back to the shop and have a correct filter put on. She stopped at Auto Zone to buy a Motorcraft FL1-A. The counter guy looked up the truck and it showed the little POS filter as a replacement. Stats show pressure, flow rate etc. to be the same but the diminished capacity of the filter bugs me.
The truck has 430,000 miles on it and it runs like a Swiss Watch with no burning oil or loss of power. My thought is don't change what's been working since the truck was new. Keep using the filter that works and uses the same amount of oil.
These new small filters save the shop money - less oil added to engine at change, and less expensive filter.
I always do my own oil changes, of course, but I told my mom to insist on the correct Motorcraft filter for her '64 Galaxie 500, '76 F-150, and '95 F-150 when she takes them in for service.
