It was purchased in June 2010 and we&#39;ve&nbsp;changed the oil 3 times and only have&nbsp;about 350 running hours on the unit. The engine oil was changed not even a year after purchase when it had less&nbsp;than 100 running hours on it before the formation of sludge and oil was discovered. A test was conducted on the unused oil and we learned that too much CALCIUM was found (about 4,139 PPM) and the presence of SODIUM and POTASSIUM.</p> </div><p><a href="http://ecmweb.com/forums/general/general-electrical-talk-discussion/formation-sludge-engine-oil-250kva-cummins-generat" target="_blank">read more</a></p> http://ecmweb.com/forums/general/general-electrical-talk-discussion/formation-sludge-engine-oil-250kva-cummins-generat#comments General Electrical Talk Discussion Tue, 21 Jun 2016 03:49:38 +0000 137091 at http://ecmweb.com Services You Wished Every Distributor Offered http://ecmweb.com/forums/general/general-electrical-talk-discussion/services-you-wished-every-distributor-offered <div class="node-body forum-body"><p>I just recently began working in the electrical field and have only worked with one distributor.
