Another Kirkland roll changed out in the Frantz. Love how the roll is compressed after running as an oil filter. Insert is 304 stainless I turned on my lathe to fit the new rolls.
No, you can run them until blocked, but I find 3000K to be the right intervals. This keeps the detergents up and the oil clean so it never has to be changed. It all depends on how clean the engine runs.
I haven't checked the Frantz filters in over ten years, but they used to use toilet paper rolls for the non synthetic filters. They just wrapped them in a nylon net. You can't get any better filtering than a toilet paper roll.
