(1) Higher phosphorus engine oils can harm the emission systems of modern gasoline engines. Infineum recommends using ILSAC oils in gasoline engines (2) Although claim is not obsolete, MAN is no longer providing new approvals and are developing a new specification for PC-11 oils. Infineum did submit application forms for this approval. MAN 3275 is obsolete, but the new specification would be back serviceable (3) Meets the engine test requirements, specific formulations need expensive bench testing for specific formulations for an official approval

PURUS Product Performance
PURUS Performance Overview Oxidation Protection Improves oxidation performance by over 60% compared to API CJ-4 technology Wear Protection Exceptional Cummins ISB wear performance demonstrated at FA-4 HTHS levels Outstanding cylinder, bearing and ring wear results (Mack T-12) Outstanding cross-head and injector screw weight loss (Cummins ISM) Excellent bore polish and cylinder wear results (MB OM501LA) Oil Consumption Control Demonstrated excellent oil consumption control in Caterpillar C13 and Mack T-12 Deposit Protection Outstanding piston deposit performance (Caterpillar 1N) Excellent piston cleanliness and engine deposits performance (MB OM501LA/ OM646LA)
PURUS Performance Overview Outstanding Wear Protection High Temperature High Shear Rate Viscosity (HTHS) Oil resistance to flow at high temperature under high load/pressure Similar to environment that exists in journal bearing Higher risk of metal/metal contact and wear Positive impact on fuel economy Reduced risk of metal to metal contact and wear Negative impact on fuel economy
PURUS Performance Overview Outstanding Wear Protection Good wear protection has always been demanded from lubricants. With lower viscosity grades for API FA-4 the need for lubricants to protect all areas of an engine has never been greater. Without balanced lubricant formulations there is a greater risk of wear. 1. Valve Train 2. Piston / Ring Zone 3. Bearings 1. 2. 3. 1. 2. 3.
PURUS Performance Overview Outstanding Wear Protection Valve Train Protection Beyond the Specification Protection Beyond the Specification - a relative measure of performance indicating by how much PURUS HDD Motor Oil outperforms the specification
PURUS Performance Overview Outstanding Wear Protection Piston / Ring Zone and Bearing Protection Beyond the Specification Outstanding All Around Wear Protection Ensures Engine Durability
PURUS Performance Overview Outstanding Oxidation Control New engine design strategies mean modern diesel engines run hotter Higher temperatures increase thermal / oxidative load on lubricants PC-11 introduces the new Volvo T-13 engine test that sets oxidation performance requirements for the category Rate of oxidation is one of the key factors impacting lubricant durability throughout drain interval
PURUS Performance Overview Outstanding Oxidation Control Enhanced Oxidation Control Maintains Lubricant Effectiveness
PURUS Performance Overview Outstanding Oxidation Control Formulated for the Volvo T-13 using a specific combination of Anti-Oxidants Hydroperoxide decomposers Preventing the formation of free radicals Radical scavengers Trapping radicals to stop crosslinking of molecules and therefore viscosity growth Delaying the onset and slowing the rate of oxidation and viscosity growth plus suppressing acid build up Enhanced Oxidation Control Maintains Lubricant Effectiveness
PURUS Performance Overview Outstanding Acid Neutralization A critical function of engine oils is to neutralize acids generated via oxidation and thus retard corrosive damage to the engine. Additives (primarily detergents) in the oil contain alkaline compounds formulated to neutralize these acids. Total Base Number (TBN) The reserve acid neutralization remaining in the oil to retard oxidation and corrosion Total Acid Number (TAN) Measures the increase of oil oxidation and build up of corrosive acids in the oil
PURUS Performance Overview Outstanding Acid Neutralization TBN will decrease over time and TAN will increase over time. The point where the two numbers meet or cross is often referred to as the TBN/TAN crossover time
PURUS Performance Overview Outstanding Acid Neutralization Superior Acid Neutralization Prevents Corrosive Wear
PURUS Performance Overview Outstanding Aeration Performance The Caterpillar Oil Aeration Test was introduced to PC-11 to protect bearings from wear due to cavitation Aerated lubricants can lead to: Oxidative and thermal oil degradation Reduced lubrication / oil supply Cavitation Noisy operation of engine Malfunction of hardware: oil pumps connect rods bearings PURUS
