That filter came off the mare at about 178K. I've had my coolant filter on the OX now for 15K like I said and I'm going to cut it open and see what it looks like. The OX now has 115K on it. Maybe I'll do it soon before this thread dies.
I, for one, would like to see it and see what a lower mileage OBS does to a new filter. Please?
I've got 156 on the old dog so she is fairly new. I just did a good flush with new coolant so I'll run the filter for 500 miles then pull it and post some pics.
Wow amazing what's in there. I ordered the filter kit from diesel site with some of the rmi25. Time to clean her up
Just to add to this great conversation. It's my understanding that you either decide to use SCAs or RMI-25 or something like Evans coolant but don't combine them. Is that how others see it?
I'm using Rotella Red with RMI-25 and therefore zero SCAs.
As I see it, SCAs are a scale that adheres to the block to protect it from cavitation. RMI-25 scavenges oxygen to increase the boiling point to combate cavitation but also removes scale and that makes them competitive.

That's how I interpret it too. Either conventional SCA's or RMI-25 but not both. I have to admit that I'm kind of cynical about all the claims on their website. Surprising they don't recommend brushing your teeth with their magical product.
One advantage I see is that they seem to claim that using RMI-25 you don't have to do any coolant testing for SCA level, just add RMI-25 every 15,000 miles and you're good to go.
They're right here in Northern Nevada and I'll call them on Monday with some questions.
I'd be interested to hear what they say about adding them together. Would it be a bad reaction or overkill? Would the rmi wipe away the SCAs but then still protect as normal? I would assume that unless someone went with a straight green coolant flush, adding rmi would always have some sort of SCA interaction if the engine was in use prior to adding it.
In this picture the filter doesn't look good but actually it looked better then the other I posted. The other one had only 4K on it and this one had 15K. I had to spread the paper plates to scrape some junk out. The other filter was coated with junk.
well everyone made me feel guilty of neglecting my filter so I changed it yesterday about 5,000 miles on it.
only fine particles, seemed to be almost totally plugged since one pleat was bulged,
From here it looks like your filter housing might be plumbed backwards. The flow should push the pleats inward, not pop them out like your picture shows.

I had my son hook it up when I re located it, hoses were backwards.
reps for your keen eye.

I called RMI today and talked to Dan Watson, he seemed like a real smart guy , he said 8 oz of RMI will treat up to 5 gallons of coolant, our trucks just use one 8 oz bottle and that it should last 15,000 miles or one year of service, he said to test the Ph level use pool test strips, also do not use SCA with Rmi.
