Engine health hinges on proper lubrication and smart oil choices
Car engines function best when they stay active. A sedentary lifestyle for an engine is risky just as it is for people. When an engine rests too long and then attempts demanding work, wear accelerates. Maintaining optimal oil pressure is key for the crankshaft, connecting rods, pistons, the gas distribution system, and for turbocharged powerplants, the turbocharger. Oil pump performance is often tied to engine speed. Staying under about 2500 rpm for gasoline engines and under 1200 rpm for diesel engines can lead to insufficient plain bearing lubrication, shortening the engine’s life and undermining reliability. This is a reminder that consistent oil care matters for longevity, efficiency, and performance. [Citation: Industry lubrication guidance]
A well-timed example shows what happens when oil is scarce: bearing wear under load. The issue is amplified in vehicles equipped with start-stop systems that repeatedly restart the engine during traffic. Studies show that frequent restarts can dramatically shorten system life. There are additional concerns in older designs and some low-speed operation regimes where valve timing components may experience soot buildup, local overheating, and potential valve wear if lubrication is degraded.

Frost introduces new complications. Moisture condensation can accumulate in a chronically cold engine sitting in the low-speed zone, and when mixed with oil, it degrades lubrication and can lead to accelerated wear. In recent years, new phenomena have emerged at low speeds in some modern engines. Low Speed Pre-Ignition, LSPI, is a risk particularly associated with downsized turbocharged gasoline direct injection engines. The goal of designers chasing high efficiency is sometimes at odds with reliability. LSPI involves a sudden, uncontrolled rise in combustion chamber pressure at low speeds, and it can cause severe damage if not addressed. [Citation: Engine design and LSPI reports]
Despite these challenges, there is hope. Many problems stem from lubrication limits, and the right motor oil can dramatically improve protection. The German company Bizol offers lubricants with a long track record in markets around the world, including Russia, and has built a presence in more than 70 countries. Since 1998, Bizol has answered quickly to the needs of automotive manufacturers and service networks. [Citation: Bizol corporate history]
Engine oil friction testing remains a cornerstone of quality control. Bizol was among the early European companies to respond to LSPI by introducing motor oils that meet API SN Plus specifications introduced by the American Petroleum Institute in 2018. These oils help reduce LSPI risk and clean carbon deposits thanks to strong antioxidant properties, while also preventing sludge formation and enabling rapid lubrication of engine components during cold starts.

High-performance oils rely on synthetic base stocks and advanced additive technology. Hydrocracking-based base oils offer resilience against moisture and compatibility with seals, enabling a robust oil film over a wide temperature range. Oils in Bizol’s all-round family suit most modern engines with exhaust after-treatment, including petrol and diesel, naturally aspirated and turbocharged systems. They are recommended for brands such as Chrysler, Ford, GM, Honda, Hyundai, Mazda, Nissan, and Toyota. The best proof of quality often lies in confidence from practitioners and manufacturers alike.

There is a segment of engines built for extreme speeds and loads. For these, oils with exceptional shear stability and a high viscosity index are desirable to sustain a durable oil film across temperatures. Bizol all-round offerings include fully synthetic options with anti-friction and anti-corrosion additives that perform under harsh conditions, and they carry recommendations from premium brands including BMW, Mercedes‑Benz, and Porsche. For questions about fitment and specifications, a consultative look at the Bizol all-round catalogue is advised. [Citation: Brand endorsements and product lines]
For many drivers, selecting the right oil remains essential. The simple answer is to check the Bizol oil catalog and choose an all-round product that fits both multi-valve petrol and diesel engines, including direct injection and turbocharged configurations. The formulation also works for engines running on alternative fuels such as liquified petroleum gas or compressed natural gas. Fiat, Mercedes‑Benz, Peugeot, Renault, and VW are among the brands that have recognized the compatibility of these lubricants. [Citation: Compatibility notes and manufacturer alignments]
The breadth of Bizol’s all-round range is notable. The lineup aims to cover a wide spectrum of market needs with a single, overarching concept. This practical approach resonates with technicians and car owners alike who value dependable lubrication across varied driving conditions. [Citation: Market positioning and product philosophy]
