Description

AeroShell Turbine Oil 308 is a 3 cSt synthetic ester turbine engine oil formulated for specific aircraft turboprop and turbojet engines requiring a MIL-PRF-7808 Grade 3 lubricant. Its additive system provides resistance to oxidation and corrosion while helping minimize wear in turbine engine components.

AeroShell Turbine Oil 308 is currently qualified to MIL-PRF-7808M Grade 3 and carries NATO Code O-148 and Joint Service Designation OX-9. MIL-PRF-7808 was formerly designated MIL-L-7808, making the older specification name an important search term for legacy aircraft and maintenance applications.

AeroShell 308 is intended for specific aircraft turbine engines where the applicable engine or equipment documentation calls for a MIL-PRF-7808 lubricant. Always verify the required lubricant specification and viscosity before use.

Features & Benefits

3 cSt synthetic ester turbine oil for applications requiring a low-viscosity aviation turbine lubricant.
MIL-PRF-7808M Grade 3 qualification.
NATO O-148 designation.
Joint Service OX-9 designation.
Oxidation resistance helps protect the lubricant during turbine engine operation.
Corrosion protection helps protect turbine engine components.
Wear reduction helps protect lubricated engine components.
Synthetic ester formulation designed specifically for aircraft turbine engine lubrication.

Applications

AeroShell Turbine Oil 308 was developed for specific aircraft turbine engines requiring a MIL-PRF-7808 Grade 3 oil.

Frequently Asked Questions

What is AeroShell Turbine Oil 308?

AeroShell Turbine Oil 308 is a 3 cSt synthetic ester turbine engine oil developed for specific aircraft turboprop and turbojet engines requiring a MIL-PRF-7808 Grade 3 lubricant.

What specification does AeroShell 308 meet?

The current Shell specification is MIL-PRF-7808M Grade 3. AeroShell 308 is also identified by NATO Code O-148 and Joint Service Designation OX-9.

Is AeroShell 308 the same as MIL-L-7808?

MIL-L-7808 is the former designation for the U.S. military specification now identified as MIL-PRF-7808. AeroShell 308 is designed for applications requiring this family of aircraft turbine engine lubricant.

What viscosity is AeroShell 308?

AeroShell Turbine Oil 308 is a 3 cSt turbine oil, equivalent to approximately 3 mm²/s at 100°C.

What engines use AeroShell 308?

AeroShell 308 is intended for particular models of aircraft turboprop and turbojet engines that require MIL-PRF-7808 oil. Engine-specific approval should always be verified against the applicable manufacturer's documentation.

Is AeroShell 308 a synthetic oil?

Yes. AeroShell Turbine Oil 308 is formulated from a synthetic ester base oil.

Is AeroShell 308 a 5 cSt turbine oil?

No. AeroShell 308 is a 3 cSt turbine oil. AeroShell products such as 500 and 560 are 5 cSt turbine oils with different specification and performance classifications.

Can AeroShell 308 be substituted for another turbine oil?

Do not substitute turbine oils solely because they have similar viscosity or appearance. The aircraft, engine, or equipment manufacturer's approved lubricant specification must be followed.

Where can I buy AeroShell Turbine Oil 308?

Business Aircraft Consumables offers AeroShell Turbine Oil 308 in quart packaging for aviation maintenance applications.
