Refer to the frantz bypass filter thread that has been posted on recently and you'll see the spinner2 video link on my post. It filters the oil to less than a micron!

I have the fs2500..oil is still black.

Over the last few month Iv'e been looking into a bypass for my truck as well as the wife's new car, plan on keeping both for a long long time and it seems like a worthy investment. The Amzoil BMK21 is very comparable (they actually claim slightly better filtration) than the FS2500 and about a third of the price. I'm not promoting or demoting either system, this is just what I have read. I'm kind of leaning towards the Frantz just for the lower cost of replacement filters, it seems that many people have good oil analysis tests to show they work very well. The BMK21 is probably next in line due to filtration capabilities, low purchase cost, and parts and filters will be easily attainable for many years to come.

That's just not right. Clean oil is amber.

You are wrong........"New" engine oil may be amber ...................But There are just as many oil colors as there are in a crayon box most companies add dye to their oil. we have about a dozen different oils we use daily at work and they range from clear to blue.

Rotella is also amber. They said that was hydraulic fluid though. I've seen clear and amber fluids.

Schaeffers has a blue ish tint to it coming right out of the bottle....

Amazing ,makes me wonder how a similar test would work with other bypass filter's? I used to use Lubrication Engineers oils, in Hole trucks and Loaders, all of theirs were red, the gear oil had a almost metallic color to it.....Great stuff but pricey!!
