The Top 5 Fastest Diesel Cars

Audi R8 TDI Le Mans

Unveiled as a concept car in 2008, this powerful diesel engined Audi uses a 6.0 litre V-12 Turbocharged Direct Injection, which sprays atomized fuel directly into the main combustion chamber of each cylinder to reach a top speed of 202 mph! With an acceleration rate of 0-60 mph in under 4.2 seconds, one would be wise not to challenge one of these beauties to a race.

Porsche Panamera Diesel

In May of 2011, Porsche added a diesel engined option to its line of 4-door luxury sedans called the Panamera. The most fuel efficient vehicle in Porsche's lineup, it utilizes an Audi 3.0 litre V6 turbodiesel engine which reaches a top speed of 160 mph and can accelerate from 0-60 mph in under 6.8 seconds.

Audi A6 3.0 TDI Quattro

Launched in 2012, the Audi A6 3.0 TDI Quattro features a turbodiesel engine that Audi redesigned from the ground up, achieving a 55 pound drop in weight compared with the previous model's engine. The redesigned turbodiesel engine will launch this lovely executive sedan from 0-60 mph in 6.1 seconds and can reach top speeds of up to 155 mph.

BMW 5 Series M550d xDrive F10

The BMW N57 3.0 litre turbocharged inline-6 diesel engine in this high performance vehicle will take it from 0-60 mph in 4.9 seconds with a top speed of 155 mph. To maximize power, the M550d uses 3 BorgWarner turbochargers to provide a quick initial boost and more power and torque at higher RPM's!

Jaguar XF 3.0d V6 Auto

As a response to the popular BMW 535d, Jaguar rolled out the XF 3.0d in 2008 and was awarded Car of the Year from "What Diesel?" magazine. With a finely tuned 8-speed ZF gearbox, the XF hits a top speed of 155 mph and accelerates from 0-60mph in 5.9 seconds.

Energy Efficient Diesel Engines Help Achieve New EPA Targets

The U.S. Environmental Protection Agency (EPA) and the Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) are working together to address 2 interconnected and globally important needs; to reduce greenhouse gas (GHG) emissions and improve fuel efficiency of heavy-duty trucks and buses. The agencies estimate that regulatory standards introduced in 2014 will lead to the reduction of 270 million metric tons of CO2 emissions and save about 530 million barrels of oil over the life of vehicles built for the 2014 to 2018 model years, providing $49 billion in net program benefits. The reduced fuel use alone will enable $50 billion in fuel savings to accrue to vehicle owners, or $42 billion in net savings when considering technology costs. A second phase of regulations to reduce emissions even further is planned for model years beyond 2018. (1)

With heavy-duty vehicles accounting for 17 percent of transportation oil use and 12 percent of all US oil consumption (2), the acceptance and adoption of the new regulations by the trucking industry is key. According to Allen Schaeffer, Executive Director of the non-profit Diesel Technology Forum, "The 4.2 million new clean diesel commercial trucks put in service from 2007 through 2015 have saved nearly 3 billion gallons of diesel fuel and delivered significant emissions reductions equivalent to removing the CO2 emissions from 6.1 million light-duty vehicles from the road for one year, and NOx emissions from all light-duty vehicles for 2 years."

Diesel engines are already favored by the transportation and shipping industries due to their unrivaled power and cost effective performance, in fact, 98% of the largest commercial trucks are currently powered by diesel engines. (3) With such a large proportion of goods being moved all over the country via diesel powered vehicles, it's clear how much of an impact vehicles utilizing clean diesel technology can have. With new developments including advanced engines, new emissions control systems and ultra-low sulfur diesel fuel, diesel will undoubtedly continue to be the technology of choice in the future of commercial trucking.


What is Rust Veto and Where Can You Use It?

Stored auto, metalworking, and farming equipment are just as susceptible to corrosion and oxidation as parts that are currently in use, especially if the equipment is being stored for long periods of time or shipped overseas. Maintenance is required to keep steel and iron surfaces protected in both indoor and outdoor storage conditions where high humidity, salt, fertilizers, or extreme weather can cause rusting. This is where Rust Veto can be useful in prolonging the life of your gears, lathes, firearms, or vehicle undercoating.

Rust Veto is an industrial grease or light mineral oil that leaves a protective film on metal surfaces, specifically iron and steel, and contains powerful rust inhibitors. It is necessary to lift or displace water during storage to maintain metal surfaces. The product’s coating may be translucent in order to leave identifying markings visible on equipment, or it may dry as a dark, tough coating. Rust Veto is beneficial for long-term storage, because it can protect indoor surfaces for up to three years and outdoor surfaces for roughly a year in harsher conditions.

The possible applications of Rust Veto, depending on which brand and formula is used, are wide-ranging. Various Rust Veto products can be used for steel mill equipment, railroad and transportation equipment, military weapons, outdoor farming machinery, construction machinery, and other industrial and automotive uses. Rust Veto is a worthwhile protectant that is just as easy to clean as it is to put on. Just brush or spray it on and clean it off with a petroleum solvent or emulsion cleaner if needed. It’s a simple way to lengthen shelf life and thwart damaging oxidation that can lead to compromised performance or expensive replacements.

The Power of a Clean Machine Sump

Quality coolant is invaluable to the metalworking process. Cutting oils like HOCUT 795-B - a popular coolant for CNC machines, bar machines, lathes, checkers, and various grinders -  are known for their outstanding performance and long sump life. But, the quality of one’s coolant is not reliant on brand alone. A clean machine sump is just as imperative for maintaining the quality performance of your cutting oil.

A dirty machine sump has more consequences than a bad odor. Contamination from tramp oil, mold, and metal chips left over from machining can compromise your coolant. Bacteria that feed off oil and other contaminants can also change the pH of the coolant mixture and lower its effectiveness. The faster the coolant deteriorates, the more money you will spend on new coolant and maintenance.

There are several steps you should follow when cleaning machine sumps:

  • First, empty the tank. Skim the surface of the coolant to remove tramp oil. Drain all fluids and remove debris, such as metal swarf, that has collected in the tank. 
  • Then, fill the tank and the pumping system with water and cleaning concentrate. Circulate the cleaning solution through the system for at least two hours for the best results.  
  • Drain the tank and refill the system with water. Pump the water through the system to rinse, and drain again. 
  • Now add water to “charge the system” along with new or treated coolant. Pump the fluids through the system to mix them properly. 

Coolant that has been treated and filtered can be put back into a clean tank to ensure a longer sump life. Even the best coolants on the market, like HOCUT 795-B, can be greatly compromised by a poorly maintained machine sump. Not only will removal of chips and debris keep your coolant clean, it will also give you a more accurate indication of how much coolant is actually in the tank.

Choosing the Right Cutting Oil

Without using the appropriate cutting oil for the type of metal and metalworking you wish to do, drilling, grinding, broaching, and other methods of metal machining can result in unwanted wear, oxidation, and chip weld. Costly wear is avoidable if certain criteria are considered, such as operating speed or lubricant formula. Since the right cutting oil can make all the difference, let’s learn about the different types of cutting oil and their best uses.

Oil Type

Your options for cutting oil will fall into several categories: straight, soluble, semi-synthetic, and synthetic.

Straight oils, made from mineral or petroleum oil, are undiluted and work best as lubricants for slower, heavy-duty applications. Unlike the excellent heat transfer capabilities of synthetic (made from organic esters and other compounds) and semi-synthetic oils, straight oils do not work well as coolants.

Soluble oils, like synthetic and semi-synthetic, are diluted. These lubricants contain emulsifiers, a mineral base, and other additives to provide good lubrication, heat transfer, and corrosion protection. These oils are the most common and cost-friendly.

Metal Type

Some lubricants are more compatible with certain materials than others. When deciding on a cutting oil, you should differentiate between hard, low-machinability materials, such as stainless steel, and softer, ductile materials, like aluminum. Tougher metals require tougher cutting oils with greater lubrication and anti-weld capabilities to prevent build up on the tool.

It may also be helpful to choose a non-staining oil for aluminum and brass parts. Cutting oils that contain active sulfur can stain aluminum and brass. Active sulfur and chlorine are often found in cutting oils with a heavy concentration of extreme pressure (EP) additives.

Operation Type

Ultimately, the cutting oil that you choose will depend on the nature of the operation. Are you grinding? Are you thread-cutting? Cutting oils serve specific functions based on the difficulty and speed of the machining.

Grinding, drilling, and milling are often done at higher speeds with low-viscosity oils. The cutting oil’s main function will be cooling, especially with a synthetic cutting fluid, since the thinner, diluted fluid carries heat away more efficiently. Thread-cutting and broaching, however, require more work and slower operating speeds. A highly viscous oil is needed to reduce friction and lubricate the surface.
You can best choose your cutting oil by distinguishing between situations that emphasize a need for cooling and situations that emphasize a need for lubrication. A strong evaluation of the metal’s properties, as well as the machining method, can indicate which cutting oil will prevent corrosion or heat-related damage.
