Cranfield Institute of Technology

(5 Year Test)

The Cranfield Institute of Technology tested our formula (while under another private label) over a five-year period of time.  Results of the extensive program, which involved designing special test equipment and testing under highly controlled laboratory conditions, lead to two important conclusions.

* As compared to ordinary oil, XcelPlus Engine Treatment dramatically extends the life of the metal.

* The product coats the metal surfaces, causing the treated "dry" metal to outperform untreated "dry" metal.

The Cranfield report adds its voice to the mass of positive test results accumulated over the years.  
     The Cranfield Institute, Cranfield, England, is known worldwide for its work in tribology, the study of friction.  This graduate university and research center specializes in advanced teaching and research in engineering, technology and management.  The largest center for applied industrial research and development in Western Europe, Cranfield was chosen to conduct the tests because of its record of research work for other important clients, including NATO.
     The tests were conducted in three different types of bearing systems designed by the Cranfield research staff.  Such systems were used because they are easy to monitor and provide the opportunity to vary load and speed, different combinations of metals, including brass, cast iron, phosphor bronze and steel, were also evaluated.

     The first system tested was the gas council rig, consisting of twelve test modules supported on gas bearing units.  These units carried small journal bearings, both solid and porous, for evaluation in conformal contact, that is, contact in which the working surfaces conform very closely with one another.  The stock oil, a mixture of 40% SAE 10W and 60% SAE 30, was used alone and with 20% XcelPlus Engine Treatment added.  The bearings were lubricated for 24 hours and then run for a maximum of 600 hours without further lubrication.  Bearings made of brass, cast iron, phosphor bronze and steel were tested with hardened and unhardened steel shafts.

XcelPlus extends bearing life

     The difference between the performance of the stock oil with and without XcelPlus Engine Treatment was dramatic in most cases.  For brass, phosphor bronze and steel bearings, the XcelPlus-treated system produced a markedly lower failure rate.
