Sourcing Overview
Select the correct aviation oil.
Avoid engine failure.
Maintain Time Between Overhaul (TBO).
Contact an aviation oil supplier.
Mistake 1: Using Automotive Oil
Automotive oil is for water-cooled engines.
Aviation engines are air-cooled.
Automotive oil contains metallic ash additives.
These additives create deposits.
Deposits lead to preignition.
Preignition causes piston burn-through.
Only source certified aviation oils.

Mistake 2: Incorrect Mineral Oil Application
Straight mineral oil lacks dispersant additives.
Use mineral oil for new engine break-in.
Use mineral oil for overhauled engine break-in.
Switch to ashless dispersant (AD) oil after break-in.
Verify break-in period with engine manufacturer.
Do not use AD oil during break-in.
AD oil prevents necessary piston ring seating.
Mistake 3: Improper Mixing Ratios
Add mineral oil to ashless dispersant oil if necessary.
Avoid adding ashless dispersant oil to mineral oil during break-in.
Maintain consistency in brand where possible.

Mistake 4: Mismanaging Aviation Turbine Oil (ATO)
Turbine engines require specific lubricants.
Select high-performance aviation turbine oil.
Verify Type I vs. Type II compatibility.
Check MIL-PRF-23699 specifications.
Review HTS (High Thermal Stability) requirements.
Incorrect ATO selection causes carbon buildup (coking).
Coking restricts oil flow to bearings.

Mistake 5: Neglecting Corrosion Protection
Engines fail from rust more than wear.
Piston engines are susceptible to internal corrosion.
Select oils with anti-corrosion properties.
Sourcing must include seasonal considerations.
Use multi-grade oils for variable climates.
Use single-grade oils for consistent hot-weather operations.
Mistake 6: Inefficient Procurement Logistics
Local sourcing limits availability.
Local sourcing increases price.
Utilize a nationwide aviation oil supplier.
Confirm reliable nationwide delivery.
Ascend Wholesale provides nationwide logistics.
Eliminate supply chain gaps.
Mistake 7: Ignoring Supplier Credentials
Verify business certifications.
Ascend Wholesale is a Woman-Owned Small Business (WOSB).
Support WOSB procurement goals.
Confirm personalized service availability.
Avoid automated call centers.
Request direct human communication.
