Product Introduction

OUNUODE Fully Synthetic CNG/LPG Natural Gas Engine Oil is a high-quality lubricant made with fully synthetic base oils, advanced additives, and a composite cleaning agent system tailored for natural gas and dual-fuel engines. It enhances engine performance by controlling oil thickening from soot buildup, allowing for longer oil change intervals while ensuring excellent engine protection.

This advanced formula offers strong resistance to oxidation, corrosion, and wear, and helps prevent deposits at high temperatures. Its long-life oil change technology, together with durable filters, supports extended maintenance intervals under normal load conditions, making it an ideal choice for long-haul fleets and heavy-duty gas engine applications.

SAE Viscosity Grade Selection Guide

SAE Grade	Climate Condition	Recommended Application

Frequently Asked Questions (FAQ)

Q: What is CNG/LPG natural gas engine oil and how is it different from regular diesel engine oil?

A: CNG/LPG natural gas engine oil is specially formulated for engines running on compressed natural gas (CNG) or liquefied petroleum gas (LPG). Unlike standard diesel engine oil, it uses a low-ash additive system to prevent ash deposits common in gas engines, offers enhanced resistance to oxidation and nitration to manage the higher combustion temperatures of gas fuels, and includes specialized detergent and dispersant additives to control soot buildup. Using regular diesel oil in gas engines can lead to spark plug fouling and valve wear.

Q: What SAE viscosity grades are available?

A: OUNUODE fully synthetic CNG/LPG natural gas engine oil is available in three SAE grades: 10W-40, ideal for cold climates and better fuel efficiency; 15W-40, the most widely used grade for moderate climates; and 20W-50, suited for high-temperature conditions and heavy-duty use. All grades comply with API CI-4 and ACEA E7/E9 standards.

Q: What industry specifications and OEM approvals does this oil meet?

A: This oil meets or exceeds a broad range of specifications including API CF, CF-2, CF-4, CG-4, CJ-4, CI-4 PLUS, CI-4, CH-4/SN, SM, SL; ACEA E7, E9; Caterpillar ECF-3; JASO DH-2; Cummins CES 20086/20081; MAN M 3275-1; DEUTZ DQC II-10 LA. It also complies with GB 11122-2006 and meets Euro IV and Euro V emission standards.

Q: What vehicles and engines is this oil suitable for?

A: This oil is designed for long-haul vehicles powered by CNG or LPG, high-speed heavy-duty engines operating under tough conditions, and dual-fuel vehicles from brands like Mercedes-Benz, Volvo, Foton Auman, and Cummins. It supports ultra-long oil change intervals and meets National V, Euro V, and Euro VI emission requirements.

Q: What is the oil change interval for this natural gas engine oil?

A: OUNUODE fully synthetic CNG/LPG engine oil is made for extended mileage oil change intervals. Paired with a durable filter, it allows for ultra-long oil change and maintenance cycles under normal load. Actual intervals should follow the engine manufacturer's guidelines and depend on operating conditions. Always check your vehicle's maintenance schedule.
