Neste Premium A3/B4 5W-40 is a high-quality synthetic engine oil with enhanced engine wear protection. It exceeds the performance requirements of the American API SP and European ACEA A3/B4 standards. It also exceeds many original equipment manufacturer (OEM) requirements and provides high performance in passenger cars and light-duty applications.

EXCELLENT ENGINE WEAR PROTECTION

Neste Premium A3/B4 5W-40 effectively protects the engine from wear even at high temperatures and loads. It forms a highly effective protective lubricating film on engine surfaces. This is achieved by a combination of high viscosity and carefully selected top-class anti-wear additives.

CLEANS ENGINE DEPOSITS AND PREVENTS FURTHER FORMATION

A large amount of detergent additives provides an effective TBN property for acid neutralization, cleans the internal parts of the engine from residues, and keeps the engine clean by forming a protective film on the engine surfaces. This helps prevent engine corrosion and extends oil change intervals.

EXCELLENT PRICE-PERFORMANCE RATIO

Neste Premium A3/B4 5W-40 oil offers a very good price-performance ratio. It is an excellent option for older engines and engines that require engine oils meeting previous generation OEM specifications. Nevertheless, it is also a very good option for new engines, as its performance significantly exceeds industry standard requirements.

EFFICIENT ENGINE LUBRICATION IN COLD AND HOT TEMPERATURES

It has a very wide operating temperature range, enabling easy cold starting and efficient engine protection at high temperatures.

Applications

Neste Premium A3/B4 5W-40 oil is recommended for year-round use in petrol, diesel, and turbocharged engines. It is especially suitable for older Mercedes Benz, Renault, and VAG group passenger cars and light commercial vehicles. Check your car's engine compatibility according to the performance requirements and approvals in this product data sheet. It is suitable for many European, North American, and Asian OEM passenger cars and light commercial vehicles. Its benefits are particularly evident in winter, if engines are started in cold temperatures without additional heaters, and in summer use, when high oil temperatures can cause excessive oil consumption if lower viscosity oils are used. Not recommended for cars with exhaust gas aftertreatment systems.
