BIZOL Allround 0W-20 — Why do you need it and what makes it so special?

Engine oils in the low-viscosity range are ideally suited for use in downsized, normally-aspirated and forced-induction engines that have the latest emission-control systems, direct injection and automatic stop-start systems. BIZOL Allround 0W-20 was primarily formulated to improve fuel economy and reduce CO₂ emissions in modern engines whilst providing premium levels of lubrication and protection.

BIZOL Allround 0W-20 fulfils the requirements of the API SP/SN Plus and ILSAC GF‑6A specifications. The sophisticated package of additives used has been developed to protect against low-speed pre-ignition (LSPI) and timing chain wear, provide improved high-temperature deposit protection for pistons and the turbocharger and much more stringent control of sludge and varnish deposits.

The fact that Allround 0W-20 meets the ILSAC GF‑6A standard is highly relevant, as a large number of hybrid models on the road today were pioneered and perfected by Asian manufacturers.

Low-viscosity oils are inherently thin, which has both upsides and downsides. Using a low viscosity oil generally improves fuel economy and emissions overall but it can also cause increased oil consumption. Consumers, however, can rest assured because BIZOL Allround 0W-20 is a lubricant which excels at maintaining exceedingly low levels of oil consumption.

BIZOL Allround 0W-20 has a multitude of benefits, such as excellent dispersing and antioxidant properties i.e., it ensures long-lasting cleanliness of all internal engine components, can prolong engine life and facilitate long maintenance intervals.

Ever since the emergence of the hybrid powertrain, there has been a continual increase in hybrid-vehicle sales volumes. The proliferation of low-emission vehicles (LEV) has steadily contributed to a significant reduction in air pollution. LEVs have made the greatest difference in city traffic where the rate of start-stop cycles is highest and average fuel economy is lowest.

Most Hybrid Electric Vehicles (HEV) and Plug-in Hybrid Electric Vehicles (PHEV) offer excellent flexibility and can be charged using a domestic power supply from the normal mains power grid. The simplicity of operation has resulted in widespread acceptance. Added to this, is the fact that governments have encouraged the uptake of hybrid vehicles by offering subsidies and tax breaks to potential buyers. Under such conditions, it is plain to see why the vehicles using this alternative drive system have become a popular ‘green’ option.

The emergence of the hybrid powertrain, however, has brought its own set of problems. Lubricant manufacturers, for example, have had to find ways to tackle new challenges associated with hybrid configurations. Ever more stringent emissions standards and changes to engine operating modes have necessitated a radical rethink of oil formulations to counteract higher wear and harsher operating conditions that these changes have caused.

All of these factors were taken into account when formulating BIZOL Allround 0W-20, meaning it was equipped from day one to meet the special requirements and exacting demands of hybrid-vehicle engines and downsized conventional engines. In many hybrids, the engine is repeatedly switched on/off for brief periods. Continually switching the engine on and off is the equivalent of a cold start over and over again in a vehicle with a conventional powertrain.

Repeated cold-starts take a heavy toll on any engine, with the arduous conditions adversely affecting the wear rates of engines in both conventional and hybrid powertrains. The need to counteract these adverse effects has, however, also brought significant benefits to conventional internal combustion engines, as the quality of lubrication has distinctly improved.

BIZOL Allround 0W-20 has been formulated to fit this tough requirement profile like a glove with its special package of additives. It has low-friction properties and rapidly provides a reliable lubrication film, even under difficult operating conditions. Its outstanding viscosity profile means the oil can provide immediate wear protection which, in turn, promotes smooth running and a long engine life.
