FAQ
4-stroke gas engines require a specific low ash oil such as Aurelia NGX 40 to ensure engine cleanliness, protection against wear, and compatibility with exhaust after-treatment systems. It is essential to choose an oil that meets the manufacturer’s recommendations and is suitable for the operating conditions (fuel type, temperature, etc.).
A gas engine oil like Aurelia NGX 40 can be used when gas is the primary fuel or is used for the majority of the monthly running hours.
Low ash oils such as Aurelia NGX 40 provide excellent resistance to oxidation and nitration, reduce deposits on pistons and combustion chambers, and protect against corrosion and wear. They are designed for engines operating under severe conditions and with various fuels (natural gas, low-sulfur diesel, etc.).
A high Base Number (BN) is crucial because it indicates the oil’s ability to neutralize acidic by-products formed during fuel combustion, protecting engine components from corrosive wear. At the same time, a low ash content - such as found in Aurelia NGX 40 - is essential to minimize deposit formation on pistons and in combustion chambers, which helps maintain engine cleanliness, prevents ring sticking, and ensures optimal performance. The right balance of high BN and low ash ensures both effective acid neutralization and reduced deposit-related issues, extending engine life and reducing maintenance needs.
