Is your current lubricant ineffective?
Or want to understand more about the complexities within the oil-based lubricant?
Within the engine design community, balance in oil consumption rates is generally strived for amongst experts.
Excessive consumption for instance is costly to operators and usually requires larger oil tanks. However, too little consumption has a negative impact on oil condition, system cleanliness, and engine longevity. Two major factors of oil consumption are deoilers and seals, and their effect on oil degradation.
One element designed to enhance the stability and effectiveness of the oil performance is additives. Although additives protect the lubricant, when they are sacrificed and consumed, fresh additives contained in makeup oil counter this reduction, and fresh oil replaces the degraded oil lost overboard due to the efficiency of the deoiler. Mobil Jet Oil II is an ExxonMobil product formulated with a combination of a highly stable synthetic base fluid and a unique chemical additive package, making it the ideal, economically efficient oil for many aircraft. Moove Aviation is an ExxonMobil authorised European distributor, and if you wish to speak with an expert regarding this oil, contact Moove directly here.
A problem often encountered with jet oil is acidity. In the instance of commercial jet engine aircraft, oil consumed is usually replenished by topping off with fresh oil. This replenishment is particularly useful when oil consumption is high, as it helps to counter the build-up of acidity. Contrastingly, when oil consumption is low, the effect is to reduce the oil replenishment rate, resulting in acidity increases over time.
In high-efficiency, modern engines, oil consumption is likely to be lower and oil system temperatures higher than in more mature engines. However, these factors have negative impacts on oil condition. In engines where the operating cycle is short and the volume/consumption rate is long – in the order of 400 hours – operators may want to consider periodic oil-health monitoring checks. Moove Aviation offers products that have been designed to operate at extremely high temperatures but also temperatures as low as -40° Fahrenheit. These include Mobil Jet Oil 387 and Mobil Jet Oil 254, both of which can be found here. Where higher oil system temperatures might be detrimental to some oils, these products have been created to last longer and consequently should contribute to an overall cheaper means of running an aircraft.
Oil consumption levels are often determined by the systems within the engines. For example, engines with carbon seals for oil sumps and deoilers installed in gearboxes frequently have lower consumption than those using labyrinth seals and deoilers in main engine oil sumps. If the correct assembling and installation methods have been implemented and have not been abnormally worn or damaged, the high oil consumption is simply due to inefficient deoilers installed on the engine air breathing system.
There are many factors to be taken into consideration when understanding how to improve the effectiveness of oil consumption within an aircraft, and of those is the lubricant being used.
