If you operate a Perkins natural gas engine, choosing the right engine oil is crucial for performance, efficiency, and engine longevity. Perkins engines are designed to run under high loads and extreme conditions, making oil specifications an important factor in maintaining reliability.
In this guide, we’ll break down the key oil specs for Perkins gas engines and help you find the right product to keep your equipment running smoothly.
Key Oil Specifications for Perkins Natural Gas Engines
1️⃣ Viscosity Grade – SAE 40
Perkins natural gas engines typically require an SAE 40 viscosity grade, ensuring stable lubrication at high operating temperatures. The oil maintains its protective film even under heavy-duty loads.
2️⃣ Low Sulfated Ash Content – ≤ 0.6%
A low sulfated ash level prevents:
✔ Deposit buildup on valves and spark plugs.
✔ Reduced engine knock.
✔ Cleaner combustion and lower emissions.
3️⃣ Oxidation and Nitration Resistance
Since natural gas engines run hotter than diesel or gasoline engines, the oil must have high resistance to oxidation and nitration to extend oil drain intervals and prevent sludge formation.
4️⃣ High TBN (Total Base Number)
A higher TBN value ensures the oil can neutralize acidic byproducts from combustion, preventing corrosion inside the engine.
5️⃣ Meets Perkins CES 20085 Standards
For optimal performance, Perkins recommends oils that meet or exceed the CES 20085 specification, ensuring:
✔ Extended oil life.
✔ Improved deposit control.
✔ Superior wear protection.
