AMSOIL Proves Superior in Clark County Field Test
In order to demonstrate the effectiveness of AMSOIL 15W-40 Synthetic Heavy Duty Diesel and Marine Motor Oil and the AMSOIL Dual-Gard filtration system in reducing operating expenses, AMSOIL and Direct Dealer Bill Andes began an ongoing field test in October 1998 with the bus fleet of the Clark County Board of Mental Retardation & Developmental Disabilities (MR/DD) in Springfield, Ohio.
Participating in the field test are three 1997 International 3800 school buses, two equipped with International 466 diesel engines and one with an International 466E diesel engine. Each had previously been running a conventional petroleum-based oil.
Prior to starting the field test, four goals were set:
|1.||The reduction of fuel consumption through the superior lubricity and reduced viscometric drag provided by AMSOIL 15W-40 Synthetic Heavy Duty Diesel and Marine Motor Oil. Verification of this goal will be obtained by com-paring previously documented fuel mileage reports using petroleum oils with fuel mileage reports of the same vehicles now using AMSOIL diesel oil.|
|2.||The extension of fluid drain intervals due to the superior synthetic chemistry and additive system of AMSOIL Synthetic Heavy Duty Diesel and Marine Motor Oil, along with the additional efficiency pro-vided by the AMSOIL Dual-Gard filtration system.|
|3.||The reduction of maintenance costs due to the superior wear protection and extended drain intervals provided by AMSOIL Synthetic Heavy Duty Diesel and Marine Motor Oil and the AMSOIL Dual-Gard filtration system.|
|4.||Provide the above-mentioned benefits without com-promising the mechanical integrity of the equipment.|
Baseline samples of the petroleum oil already in the crankcase were obtained, tested and documented. Next, the oil was drained and the engines flushed with AMSOIL Engine Flush. AMSOIL BMK-12 Filter Mounts, two BE-110 By-pass Filtration elements and AMSOIL 15W-40 Synthetic Heavy Duty Diesel and Marine Motor Oil were installed in each vehicle.
Oil samples from each bus are drawn and tested at 4000-mile intervals, the normal oil drain interval practiced by MR/DD when using conventional lubricants. Data obtained from the oil samples serves to determine the following:
|1.||Fluid and vehicle baselines|
|2.||The mechanical condition of the vehicles|
|3.||Ability of the equipment to continue functioning as a demonstration vehicle|
|4.||Rate of internal equipment wear|
|5.||Serviceability of fluids and filters|
Once drawn, each oil sample is reviewed in the areas of elemental analysis (including wear metals, contaminates and additives), physical properties (including viscosity, total acid number and total base number) and contamination (including water, solids, glycol, oxidation, fuel soot and fuel dilution). Oil condemnation limits vary due to individual engine idiosyncrasies, operating conditions and time the fluid has been in service.
