Why Aircraft Engine Oil Matters
Aircraft engines operate under very different conditions compared to car engines—high RPMs, constant loads, and wide temperature swings. That’s why aviation oil isn’t optional; it’s critical to engine health and safe flight.
Good aviation oil:
-
Lubricates moving parts under load
-
Cools internal components
-
Prevents corrosion during storage
-
Suspends combustion byproducts
-
Protects against lead fouling (especially in 100LL-fueled engines)
How to Choose the Right Oil for Student Pilot Aircraft
Here’s what to consider before buying aviation oil:
🔧 1. Engine Type
Most training aircraft (like the Cessna 152, 172, and Piper Warrior) use Lycoming or Continental engines. These typically require SAE 50 (W100) or multi-grade oils like 15W-50.
🌡️ 2. Climate/Season
-
Hot climates: Use straight-weight oils (W100 or W120)
-
Cold or variable climates: Use multi-grade oils (15W-50) for easier starts
🛡️ 3. Additive Packages
Some aviation oils include anti-wear, dispersant, and corrosion protection additives, ideal for aircraft that sit for days or weeks between flights (like student-rented aircraft).

When to Change Oil in a Training Aircraft
While oil change intervals depend on usage and environment, a general guideline is:
-
Every 25–50 hours for mineral oils
-
Every 50 hours or 4 months for semi-synthetic/multigrade oils
-
Every 4 months minimum if the aircraft isn’t flown regularly
✈️ Always refer to your POH or mechanic for engine-specific intervals.
Can You Use Automotive Oil in Planes?
Absolutely not.
Automotive oils are not designed to handle leaded fuel, high engine temperatures, or the unique demands of aviation engines. Using them can void warranties and cause engine damage.
