When the oil is cold and the fuel air mixture is enriched. Rowing it through the gears at higher than usual RPMs, racing. All these conditions are elevating blow by particulate to the crankcase. An article from BITOG about filter bypass valves and when they open.

This too can be argued. How long does it take for the capacity of oil in the pan to circulate? Couple mins? If that. So you idle for say 3-5 min, on a warmed up engine, and all the oil has passed through the filter, right? Under no load? Then you make a blast/pass. How much contaminates are going to be produced in that time? It's not going to be saturated, right? So the next few mins of normal driving, all the oil passes through the filter. So it gets filtered. It's not like the oil is in bypass 80% of the time.

Which brings up another point, how long does it take for the entire contents to pass through the bypass oil filtration system? Probably what, 3, 4, maybe 5 times as long as the primary filtration system?

Let's touch on Blackstone Labs. Who do they get their' funding from? Have you ever seen the movie 'Thank you for Smoking'?

Again, I'm not arguing the fact that there are benefits from running a bypass filtration system, I'm just questioning some areas that are not 'clear' to me, these are probably common consumer-type concerns/questions.
