DOES START STOP SYSTEM WEAR OUT ENGINE COMPONENTS?

Advantages of the Start-Stop systems
The majority of modern engines in passenger cars and light commercial vehicles are nowadays equipped with a start-stop system. An automatic start-stop system automatically switches off the engine when the traffic lights turn red, for example, and starts it as soon as the accelerator pedal is pressed. This process reduces the time the engine spends idling. The advantages of this development are reduced CO2 emissions and lower fuel consumption. In stop-and-go traffic, this technology can help you save a 3 % to 10 % fuel!
Disadvantages of the Start-Stop systems
However, some engine components suffer a critical increase of tribological stress because of frequent start-stop. Up to 75% of engine wear and wear-related failures happen during the engine starting process. If compared to equivalent engine configurations without this system, frequent start-stop intervals can double the damage to bearings. Therefore, despite the general assumption, specially developed engine oils for stop-and-go traffic or start-stop systems are important.
Wear on important engine components
The automotive industry is aware of this and is therefore working together with lubricant manufacturers to provide reliable engine oils that permanently protect the longevity of engine components, even under increased stress from start-stop systems. Wear affects mostly camshaft bearings, balancer shaft bearings, main bearings and connecting rod/piston pin systems. Additionally, engine oils with an extremely low viscosity, used for fuel economy, can have a deteriorating effect.
Synthetic oil BIZOL Green Oil+
With the Green Oil+ series BIZOL offers special engine oils which counteract the increased wear in city traffic or via start-stop systems. Intensive and time-consuming test sequences have led to further developments which are necessary for this challenging operation. The Green Oil Plus series has a large number of special wear protection properties that go beyond the “minimal sufficient” specified by the engine manufacturer.
BIZOL COMB LubriBoost Technology
For example, the BIZOL COMB LubriBoost technology in Green Oil+ increases the lubricating film strength twice over. This prevents the lubricating film from collapsing when there is no relative movement between the mating surfaces, as is the case in stop-and-go traffic. To keep the engine in top condition beyond the warranty period, experts recommend the use of a special start-stop suitable engine oil.

The melodious purr of a motor, the velvety transition of cog-wheel, and the elegant voyage along the expansive highway — these are the unmistakable characteristics of a meticulously calibrated self-shifting gearbox system. But what transpires when the motorized ensemble falters, the cogs gnash, and the voyage veers into an unforeseen tempest? Get into the realm of automatic transmission problems, a domain where automotive aficionados and everyday motorists alike encounter the enigmatic intricacies of this complex system.
Driving is a blend of exhilaration and convenience, but sometimes, your trusty car can hit a snag. One of the most frustrating issues is a coolant leak.
Coolant, often referred to as the versatile 'antifreeze,' assumes the uncelebrated role of an automotive guardian, ensuring your engine's harmonious operation. This unassuming fluid stands as a bulwark against the scorching summer heat and the bone-chilling cold of winter. Nevertheless, when the vigilance of antifreeze wanes, and it embarks on an unauthorized journey beyond its confines, ominous troubles come into view.
