Hubert, thanks. I also had read that as well but, just did not think it would apply to a quality fuel station!? Now I know.

I tried to post pictures but I will have to reduce the size yet some more before they will upload. Stay posted!

I had to modifiy the device for the diesel since a diesel engine does not develop vacuum like a gaser does with a PCV valve. With this device I am pulling about 0.5in WC at idle with a stock filter.

It will be about 1800 more miles before I change oil so, we will have to wait until then to see if this condensor keeps my diesel oil clean like it is on my 92 Ford Ranger. The Ranger now has about 1800 miles on the oil and it is only slightly discolored - usually quite black by then!

In about 500 miles I will open this container to see what is in it and post an update. This will be an indication also of how well it will work in keeping the oil clean. Until then, hold your breath!
