Because of low-sulfur requirements of today’s fuels, most engine OEMs have service bulletins or information letters detailing the need for a lubricity improver. This is a very economical way to reduce wear in fuel pumps and controls and lower overhaul costs in the future by reducing the number of parts needed during overhaul inspection.

If you’re not familiar with lubricity improvers, this excerpt from ASTM Specification D1655 Section X1.10 explains it well:

“Aircraft/engine fuel system components and fuel control units rely on the fuel to lubricate their sliding parts…The chemical and physical properties of jet fuel cause it to be a relatively poor lubricating material under high temperature and high load conditions. Severe hydroprocessing removes trace components resulting in fuels that tend to have lower lubricity than straight-run or wet-treated fuels. Corrosion inhibitor/lubricity improver additives are routinely used to improve the lubricity of military fuels and may be used in civil fuels.”

LubriBor lubricity improverThe ASTM specification goes on to state that problems from low lubricity fuels range from “reductions in pump flow to unexpected mechanical failure leading to in-flight engine shutdown”.

I’m pleased to announce that LubriBor is now available for purchase through MPAC Aviation.

I have been an advocate of LubriBor for many years. LubriBor has been approved for use in aviation fuels and is used in military aviation turbine fuel both as a corrosion inhibitor and lubricity improver.

If you have questions about how a lubricity improver can help you, let me know – I’d be happy to discuss the benefits with you.

If you are ready to begin using LubriBor in your aircraft, you can start your order here.

Having worked in the aviation industry for more than 40 years, I've seen just about every aspect of the accessory overhaul business. From working in inspection, production, and management roles in accessory shops to being a customer of those shops, I can tell you there is a better way to manage engine accessory overhauls. I founded MPAC Aviation Services LLC with the mission to serve customers the way I want to be served.
