[QUOTE=HWYSTR455;5500814]This too can be argued. How long does it take for the capacity of oil in the pan to circulate?

I would say most oil pumps can do 8-12 GPM @2500 rpm so.....30 seconds?

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.

I think unless the filter is new and clean, it would be interesting how much it actually does bypass. Bypassing the pressure relief on the pump a lot when cold, and then the oil bypassing the filter when the filter cant keep up with the flow. Cold or high pressure, its not being filtered.

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?

Maybe 5 times longer, yes, but the oil is cleaner than it will ever be. Clean oil picks up contaminates and delivers them to the full flow filter which takes out "boulders" then the By Pass filter , takes out the "sand"

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

They have nothing to gain by "lying". If you dont like what they tell you, ignore them, they dont care. Just my Opinion. ; )

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.
