Is It Time For A Brake Service?

Posted on: 30 July 2020

The ability of a car to shift its gear ratio is critical for achieving the desired speed. For optimum performance of a vehicle, an automatic transmission fluid (ATF) is used to lubricate and minimise friction of the movable parts in an engine. Choosing the right ATF can enable you to avoid costly transmission repairs since gears shift smoothly without resistance. Some drivers are unaware of what to consider when choosing an ATF. This article highlights critical considerations when buying an automatic transmission fluid.

Synthetic and Conventional Transmission Fluids

Your choice of transmission fluid has a significant bearing on a car's performance. While both synthetic and conventional transmission fluids are available in the market, choosing the right type will help you to avoid multiple engine issues. Despite synthetic fluids being expensive, they guarantee superior engine performance, and they are effective at higher temperatures. Synthetic transmission fluid contains special additives to protect an engine from malfunctioning during to increased stress. However, it is better to rely on conventional transmission fluids in some instances, especially if your car is an old model. Most importantly, talk to your service dealer for advice on the best ATF for your vehicle.

Temperature

The temperature of an ATF is critical because it ensures that oil functions without losing its physical and chemical components. As the temperature in an engine rises, an ATF is placed under significant stress while preventing friction of the movable parts. Despite the pressure, a high-quality ATF should not lose its properties since it is likely to affect the performance of an engine. Before buying an ATF for your engine, inquire if the lubricant is designed for extreme conditions to protect your engine and transmission system.

Viscosity

Fluid design plays a vital role in the long-term function of an engine. In recent times, end-user demands, including improved fuel utilisation, superior engine power and better engine performance have resulted in the development of newer transmission fluids. Notably, low-viscosity lubricants have taken centre stage since they guarantee optimum fuel efficiency. Low-viscosity oils produce less friction when a car is a motion, thereby minimising fuel consumption. Unfortunately, reduced bearing and gear durability is recorded when less viscous fluids are used in a transmission system. On the flip side, high-viscosity lubricants have a better clutch and hydraulic performance due to its molecular composition that is characterised by high resistance. However, fuel consumption is far from efficient. You should choose between low- or high-viscosity transmission fluids based on requirements.
