hello guys. i have been reading this forum for a while now and still have not found any info from anyone on a better way to clean the lube oil. now at over $36 a gallon for royal purple oil times three gallons and the cost of filters. some better way needs to be found. i have been reading about oil centrifuges from a few places and think this might be a better way to make the oil last longer. my question is has anyone else installed this unit and if so what were the results. were you ok with the way the unit worked and how was the ease of cleaning the unit. also how hard was it to install on the engine, and what mods did you need to do. brand name?. what engine installed on?.i have a 05 dodge 3500 as well as a 99 ford e350 power stroke. any comments?.
