Reply to "Pre-filling oil filters?"

As for engines being robust, I heard that you actually don't need a filter after the first few oil changes where you are filtering out machining debris and casting sand particles that remain from manufacture.

Yep, depending on how much sand is in your engine, this is true.

quote:
I recently ran a 4400 mile oil interval on my motorhome with a filter having an efficency of 68 percent at 30 microns

That's a bad efficiency.

quote:
But this filter flows 15.85 gallons per minute, nearly twice that of a Purolator filter

And this the effect of the bad filter efficiency. Filterfiness and pressure drop vs. flow rate build a simple equation.
