Until the late 20th century, diesel fuel additives were not so much of a hot topic. Due to the robustness and versatility of the diesel engine, suitable diesel fuel is made from a mixture of straight-run distinctive distillation elements. With the increasing demand for fuel, the demand for diesel fuel additives has also increased. Even though there is no particular definition of what exactly an additive is, the consensus is that an additive is something added at less than 1% w/w (i.e. 10,000 mg/kg or 10,000 ppm).

Owing to this low additive rate, the physical features of the fuel, as its volatility, viscosity, and density, do not change significantly.

Cars break down, and when you are under the vehicle and repairing it, safety becomes the most important thing, both for you and for the automobile. There are a number of tools available in the market designed to ensure a safe working environment, and jack stands are among them.

One of the most obvious and common ways to keep yourself safe while lifting your car for repair is to ensure you have a good, high-quality floor jack. However, a floor jack alone can only help you so much. This is because floor jacks comprise moving parts that are prone to damage and wear, and they can become weak over time or outright fail with time and use. The scariest and most dangerous part about floor jack letdowns is they typically come in the form of a slow leak.

As such, they are infamous for slowly letting a vehicle down on top of someone as the hydraulics drop pressure and the risk situation is usually noticed once the damage has been done and it becomes too late to escape. This is exactly why it is never a good idea to crawl underneath your car when the only support it has is from a floor jack. So, what else should you do to make an elevated car safe to crawl under? The answer is simple: add a jack stand.

Jack stands are the primary tools for preventing cars from collapsing and slipping by providing strong support. It is important to keep in mind that jacks stands are not 100% foolproof and it is therefore advised that you invest in at least two of the best jack stands. This way, should a car collapse, the stands will share the load over a larger area equally and thus prevent accidents. They are tripod or tower-shaped and designed to support the hefty weight of a mounted vehicle. They should be placed under the vehicle frame or axle to offer added support for a raised car.

After a vehicle is jacked up, the stands are put back in place and the car is lowered onto the stands. The saddle-shaped parts on jack stands are there to support the car axle. These stands should only be used on flat and hard surfaces and only for automobiles that fall under the weight limit of the stands.

You can find jack stands in different kinds and they are categorized by weight capacity and maximum height. Most of the time, the jack stand’s weight capacity is expressed in tons and the height in inches. Typically, they are sold in pairs and usually used in combination with floor jacks. The weight capacity of the stand can go from 2 tons to 25 tons. The height can range from 13 to 25 inches and can go as high as 6 feet.

A Blow-Off Valve (BOV) is an important component of a turbo system that goes by many names, such as a pop-off valve, diverter, recirc (short of recirculation), bypass, and dump. The lingo tends to change in different countries and regions, but the purpose of all these valves is the same. To help you better understand the function of this vital component and avoid confusion, we will refer to all types as BOVs.

Typically, the objective of a blow-off valve (BOV) is to ensure the reliable and smooth drivability of a car, while protecting the turbo system against significant damage. This valve is responsible for producing the loud sound turbocharged engines usually produce. Where most usually replace their BOVs for sound, others do so for performance.

Regardless, it is imperative that if you have a turbo system, you choose the right valve for your ride to keep your engine healthy and happy. For more information about BOVs and how to choose the best blow-off valve, read this guide below:
