Bypass oil filtration

Recommended Posts

So I go to change the oil for the first time on my new to me granite dump.i notice that it has one of those Ops eco pure oil bypass filters.im guessing previous owner installed it to keep oil cleaner since these Ami engines are so dirty.Has anyone here had any experiences with these systems?what kinda oil change interval can I expect?I looked at the prices for Ops filters and they are like 40$ a pop.i wonder if any other brand would work or if the ops system only uses ops filters.please advice .thanks in advance .

IMO- get rid of it. All of the guys I know running those kind of set ups have been skin flints (not driven for a “green”, waste oil free, Earth) trying to stretch their  oil changes past a natural interval. In fact, if I had the choice of two, id buy the one without it. The Centrimax is perfectly engineered to remove the AI engines high soot. If a guy checks his oil samples, has a tuned engine, changes the centrimax each round and follows factory intervals you end up around 3% soot and a healthy engine. 5% is max per Mack.

Back in 2006 we got a service contract for a small fleet of new CXN’s that had the OPS aftermarket oil filter setup on them straight from the factory. We removed them with in the first year and followed the standard service procedures. They ran those trucks for at least 8 years with no oil related issues. Not worth the hassle. These systems are still a factory option as back in the summer I had to work on a new MRU that broke down while being delivered due to a oil leak on the OPS system.

Yup and in typical Volvo Fashion they only used the excellent centramax half a year on the MP7 and then deleted it! Baphoons! Another Good  Mack design swept under the carpet by the Volvo  people!

If a guy was really conciencious, above the line, concerned, for what his engine is doing........ get the wife a new kitchen scale for Christmas. Throw your centrimax on her old kitchen scale after your oil change. Write the normal (carbon loaded) weight on the scale as your baseline. When you see the weight going up you have engine issues. Dirty injector, blowby, etc.. 

If you’ve never chopped one of your old centrimax open, do it for curiousity. Looks exactly like a big zinc-carbon battery inside. Black, dry, carbon clay.

I have seen these full to the point of not being able to spin! That cartage was heavy, This  customer was  so lax on his oil changes Because the engine was" leaking so much oil " he decided it was not necessary to change the oil or filters! amazingly 25 thou plus hours and still going!

MACK Tough!
