Why Keeping Your Aircraft Lubricated is Important

Aircrafts are probably one of the most useful machines invented but with complicated parts that need lots of tender loving and care. For aircraft mechanics, their own version of TLC is spelled through regular scheduled maintenance, or spot cleaning, and proper lubrication.

In this article, we will talk about lubricants and what they do for your aircraft’s engine. We will also talk a little bit about some tips on how to always keep your engines lubricated, and of course, what the benefits of keeping it so are:

BENEFITS OF LUBRICATION

The first benefit of lubricating aircrafts is that it keeps your engine clean.  Some mechanics claim that the gunk and corrosion inside the engine is caused by the sediments left by various oils used in the engine. However, experts would argue that all aviation oils help clean this part. To define this process of internal cleaning, experts describe it as more than just scraping off oil or grease on metal, or washing off oil on cooking pans after cooking burger patties.

“When a lubricant keeps your airplane engine clean, it also means a clean ring belt area and a better control of the combustion process. When those rings are able to move freely, your engine operates at higher efficiencies, has better ring seal, produces less blow-by, and consumes less oil,” says Harold Tucker in his 1998 article published in Aviation Pros website.

“A dirty ring belt restrains the movement of the rings within the grooves and they can’t seal. This may create pressure between the ring face and the cylinder wall — leading to wear, scarring or scuffing,” he added.

The second benefit is cooling. Tucker said air-cooled aircraft engines depend heavily on oils and lubricants compared with water-cooled automotive engines. Experts would note that oil typically cover about 40 percent of the engine’s cooling system. And since we are talking about aircrafts, aviation engines have a higher percentage of heat and so it needs more cooling system that has a higher capacity. Not only that, but oil also serves as a heat-transfer medium that travels through the crankcase and oil coolers, then it disperses the heat from all the moving parts, and so the end result is that engine bearings and piston rings are cooled consistently. Without the oils on the cylinder wall, the rings would be constantly sliding with each other causing high level of friction that can lead to melting, galling, or scarring of the metal surfaces.

Last on the list is that aviation oil helps components reel in a good seal between the rings and cylinder walls. Not only that, it also helps protect and seal the gasketed areas and the rubber or synthetic seals for the crankshaft. Experienced mechanics said that when oil coats the component, it helps retain a seal. So, it is important to use an aviation oil that is compatible with your seal materials so that the seal itself lasts longer.
