I don't trust I'd ever get it 100% clean. And for $220, I'd rather just keep buying my synthetic filters at $8 a pop. $8 every 5,000mi I get 135,000mi before this would pay off, and even then, I wouldn't trust it. Posted via Mobile Device
so better means a higher filtration i.e. so many micron filtration.
the problems is that at a high filtration flow could be impaired if the filter gets to many particulates. the other concern of mine is that how do you clean it? back flushing?
particulates can sometimes lodge in the filter material. thereby clogging it.
Aside from the break even points, if it has a lower micron rating (allowing less particles through) it will 'clog' faster thus forcing you to change the filter more frequently and potentially waste all that good synthetic fluid.
In the long run, you could look at it as never breaking even due to having to buy more synthetic oil on your now lower milage intervals.
