Effects on oil filters in Euro4 & Euro5 vehicles.
Analytical Results:
Recent analysis on Euro4 and Euro5 trucks for the content of Motorsilk™ Engine Oil treatment, in some cases, , have shown that as much as 70% of the active element in the treatment has been collected in the oil filter, on first application, thereby preventing full and proper accumulation of the Boric Oxide CLS Bonding. This is a particular problem when the EOT is added to old oil and filter as there may be insufficient capacity in the filter to absorb the carbon deposits loosened from the engine.
Euro 4 and Euro 5 trucks from manufacturers including Mercedes, DAF, Iveco and Volvo have oil filters with a >10 micron particulate filter size.
The active elements of the E.O.T. whilst only 4% of the applied quantities, with the 96% residual being the carrier Mobil 1, has a micron size of ≤1-≤2, it should pass through and yet up to 70% has been collected in the filter. This is a large proportion and will affect the desired overall results.
Reason:
During the first warm up hour after application, or the first 250/500 miles of use, we know that the E.O.T. causes the removal of sludges, varnishes and carbon deposits which are collected in the oil filter. Collection of these large volumes of deposits, particularly in vehicles with 100,000+ untreated miles, causes blocking of the filter and reduce the micron size down to a level which collects the particulate boron before it has an opportunity to form the CLS Bond and adhere thereby preventing recirculation.
To fully oxidize, Boron requires 4-5 cooling periods in which the water vapour and Boric Acid chemically react to adhere to the metal surfaces. If only 30% of the active elements are remaining to form the Boric oxide, insufficient remains in the engine to coat the surfaces. E.O.T. will then be seen as failing where in actual fact it has been removed into the filter.
Solving the problem.
Always start with a new filter. After the warm up hour when a new filter is added, or the change of filter after 250/500 miles, re-add E.O.T. again. It is recommended that for a 35 litre sump capacity, 2 litres of E.O.T are re-added at this time.
