It's not whose name is on the filter that guarantees clean oil, its the type of filtration or lack of filtration that pollutes the oil and causes you to have to dump it to stop premature wear.
The basic premise is, you change oil every and filter every 3-5,000 miles because a full flow oil filter only filters out big stuff and when it turns black that's the stuff your full flow filter keep recirculating. The oil is is saturated with small particles that are wearing internal parts in your engine that your oil filter is incapable of removing.
Your choice is improve the system by adding a system that does filter out those small particulate, or dump the oil even though it's dirty because you have a compromised oil filtering system.
If you put a different system in you can easily extend oil life 3 plus times by having an efficient oil filter. You also eliminate the time the small particulate is wearing out the engine parts that the full flow filter is never going to remove. Stop sludge buildup by eliminating the small dirt completely from the oil. Stop acid formation by trapping condensation moisture that forms acid, no full flow filter traps water. By taking all the contaminants out of the oil the additive package is no longer taxed and lasts much longer.
Now you can run the oil 20,000 miles and only change the filter from the top in 5 minutes 3-4 times in that 20,000 miles. If you have the oil analyzed and it checks fine you can run it longer.
My own truck I ran 25,000 miles just changing filters in 4 years. Think of the 8 oil changes with 8 qts.(64 quarts total) 8 spin on oil filters, and I avoided and all the time changing oil I saved myself, plus getting rid of 8 gallons of drain oil.
The filter system saved me enough to completely pay for the better filter system, plus a lot of time.

So if you have not changed your oil in 25,000 miles because it is still clean, ok but not changing the filter in that time, don't you think even if it does not do a good job on small parts it will clog up with big parts and then you have no flow except your little 1/8" bypass.
