Changing filter every other oci

I am not sure what an ultraguard is.

The day after any data is published, a product change can occur.


The chart you see with Ultraguard is referring to the AC Delco product which is a synthetic media filter.

The Fram synthetic filter is just called Fram Ultra, which used to be called Fram Xtended guard

Exactly. In fact, if I recall correctly, that chart was published by AC Delco to show that their full synthetic Ultraguard flowed the best compared to the others.

There used to be that recommendation in the odd agricultural OEM and power sports OEM manual, too. We always used a new filter each time.

I would think when those manuals were written that people knew about the life expectancy of filters of that time.

Well, one would think so. I was always a bit skeptical, and still would be, because agricultural and power sports stuff can both get some really different duty cycles. Both can be used in some freakishly dusty, dirty environments, while others face some pretty easy, clean lives.

No doubt the agricultural and industrial manufacturers have people on staff to take care of the application details of routine maintenance. Some of the filters used are huge for a reason. A dozer may not see service for a year and be expected to run in dust. A farm tractor is regularly working in dusty conditions. Then there is the hydraulic filtration needs for the hydrostatic transmissions. Imagine the cost of maintaining some of these machines.

Well, back in the day, at harvest time, air filters for the fresh air into the cab would have to be serviced at least once daily. A contraption had to be put on the radiator to keep the vanes open. And, of course, there were bowls and prefilters on the air filters. None of this would be a problem through much of the rest of the year. So, yep, one could expect some variation in filter life, be it air or oil. As for costs, I remember when the PTO shaft broke on an old Case tractor. We had to drain the hydrostatic fluid, and there was over 100 L in there. That was not a fun time.

Most of the oil filters were pretty large, of course. Stuff that might be used for other purposes, such as garden tractors, might see something a little smaller in the way of filters, especially these days.
