Mixing different types of grease may deteriorate the system's performance, such as increased consistency. Pressure Lubrication System: This system is used, because the splash system is not sufficient for larger engines like Ambassador, Jeep, Ashok Leyland, and others. Lubrication Regimes Lubrication is usually classified into one of three re gimes: solid film, mixed film, or liquid film. Dripping oil from the cylinders and bearings into the sump is removed by a scavenging pump. The 2 most common lubricants you'll be dealing with daily are oil and grease, however, your facility will still be using dry and penetrating lubricants. The major concern caused by too high pressure oflubricating orjack ing oil is that it,increases the risk of system overpressure failure if the reliefvalve(s) failed to operate.
