This is why you must use either P.O.A. or laboratory Fluids Analysis when going past the 5,000 or 10,000 km mark. P.O.A. will tell you with a degree of accuracy over 90% (generally 95 to 96% +) what the state of your oil is like and degree or % of contamination. To some degree this depends on the calibration of the unit and experience of the operator. That is why we only quote over 90%. (Please remember that accurate laboratory Fluids Analysis will give you results in ppm.). It (p.o.a.) is a 30 second test and by leaving a wide safety margin and testing regularly you can insure your oil is up to scratch, does not have major acid build up, and will still perform as per the manufacturers standards which are based on SAE, API, or other Intl standards and specifications. Accurate laboratory Fluids Analysis is the only way to get 100% reliable results and when used properly with a decent P.P.M scheme can establish a reliable wear pattern and using Trend Analysis can establish extremely reliable results. The difference is the cost and time period involved. Fluids Analysis gives you a breakdown in ppm for various metals and elements depending on the tests involved and upon analysis can give you reliable results which can be used for the timely replacement of various components and parts before they become major problems and cause excessive downtime. Many knowledgeable and experienced freight companies are now using this for greater reliability and to achieve much lower operating costs. P.O.A. on the other hand will not give you individual results for any of the metals or other elements but a result in terms of overall contamination which can be relied upon to give you a accurate statement of your oil condition. When the two are used in conjunction greater reliability and lower operating costs results. MIL-MAC as such does not have a scheme in place. They are a by-pass filter manufacturer who happen to make a good filter and whom I am working in with promoting and selling their product. On the otherhand I do and along with their filters I am trying to promote the use of P.O.A., Fluids Analysis, and PPM schemes. > My '82 Hilux with 2L diesel engine is a particularly smokey performer hope > to alleviate that with biodiesel in the future) and contaminates the oil > heavily with carbon (rings aren't what they should be after 350,000km). > Would a bypass filter remove this contamination and if not what would be the > result continued buildup of the carbon with prolonged oil usage? ** Unfortunately you can not turn the clock back and the wear that exists is the major cause of the smoke although injectors may be and proably are a contributary factor. While a by-pass filter would double the life of the engine remaining it would not in my opinion be a wise investment as with a vehicle like this that is almost almost 20 years old it probably will not last that much longer. (probably 2 or 3 years at the most without major expebditure). While I could and would like to sell you a filter and it would remove almost all of the carbon in the oil it will not stop the oil getting past the rings into the combustion chamber which is probably causing the exhaust smoke. The only way you really know is when you know exactly how much oil the engine uses. If it uses virtually none or very little then get back in touch with me by all means. In my opinion you would be better to invest the money you would spend on a filter into a new vehicle and then instal a filter in this. Sorry if I sound pessimistic but I dont want to rip you off or be any impediment to your investing in a better vehicle. There are vehicles that should be off the road or are candidates for an engine replant and I expect your vehicles is rapidly heading that way. B.r., David > Thanks, > Paul.
