Instead of listening to opinions on the net, educate yourself about by pass filters, that's what I did. I know of no downside of the product whatsoever.

Blackstone labs, which FJ has referred to in his posts for oil analyzation, is a proponent of by pass filters in any and all engines. If you're attempting to run extended oil change intervals, a by pass filter will allow you to run many times over the manufacturers recommendations safely.

Of course the recommendation he makes to have engine oil analyzed for anything you want to know about the engines health, and the oils life is needed for a program other than stock engines following manufacturers recommendations.
