CH-4 Diesel Engine Oil, offered by Arian Petro Idea, is a high-performance semi-synthetic lubricant developed to meet the needs of engines operating under severe operating conditions. This special product, suitable for buses and trucks from 2004 onwards that are equipped with emission control systems (EGR), is produced from high-quality base oils combined with advanced additive packages.
CH-4 oil is fully compatible with diesel fuels with a maximum sulfur content of 5000 ppm and with excellent resistance to oxidation, corrosion, deposits and wear, increases engine life, improves fuel efficiency and reduces maintenance and repair costs. This oil is a reliable choice for heavy-duty fleets, especially in heavy-duty transportation, industrial and on-road applications, due to its excellent thermal stability and stable lubricating properties.
Choosing CH-4 engine oil means ensuring optimal performance, reducing engine failures, and achieving the highest level of protection in harsh and heavy-duty operating conditions.
Features
- Excellent resistance to oxidation at high temperatures
- High power in controlling soot and combustion particles (excellent cleaning and dispersing power)
- Excellent stability against reduced viscosity in long-term operations (excellent shear stability)
- Protects engine parts against wear
- High total alkalinity (NBT) for better protection against oil degradation
- Optimal volatility and thus reduced oil thinning
