ISX 435 OIL PSI LOSS

I used 3 types of filters during this study. First is the Luber finer filter. I lost oil pressure with this filter around 7500 miles into oil change. I'd use same new filter to finish out my 12000 mile oil change. Then I switched to Fleet guard oil filter this got me about 9500 miles before pressure loss. Then again I used same filter to finish my miles out for next oil change. The best filter I found for this oil pressure loss was the Donaldson. I was able to reach my 12000 mile mark without filter change intermittently. I hope I helped with someone's headache with this common problem with the ISX. Next year I may switch oil and try 3 different filters to find even better solution.

I will assume this is not an advertisement for the moment, though is suspicious looking. anyways, how about



FIXING THE SOOT PROBLEMS AND MAKE THE ENIGNE RUN RIGHT INSTEAD OF TRYING TO BANDAIDE THE THING!!!!!!!!!!!!!

YOUR "STUDY" MUST NOT HAVE INCLUDED ACTUALLY FIXING THE DAMN ENGINE PROBLEMS -- BUT TRYING TO MASK THEM INSTEAD --- WAKE UP!!! -- IT IS NOT NORMAL AT ALL, NOT ONE DAMN BIT FOR AN ISX TO PLUG OIL FILTERS LIKE THAT!!! -- SOMETHING IS WRONG WITH THE ENGINE!!!
