Why Use a Fuel Injector Cleaner?

4732There are a lot of products you’ll find on the shelf that say they’ll help your car’s performance and mileage.  Fuel system treatments and fuel injector cleaners are popular among these. But do you really need a fuel system treatment? What exactly does a fuel injector cleaner do for your car?

Well, like most things in life, there’s good and bad – formulas that live up to their claims, and others that do virtually nothing.

Your fuel injectors deliver fuel to your engine and are crucial to the performance of your car. The problem that fuel injectors encounter is that most gasoline contains ethanol to boost octane, which oxidizes and emulsifies, resulting in a buildup of byproducts on intake valves and in the combustion chamber of the engine. What follows can be reduced engine performance, higher emissions, lower fuel economy and other negative repercussions. Yes, even with modern detergent gasolines.

A fuel injector cleaner or fuel system treatment is easy to use — you just pour it into your gas tank and it protects your engine against fuel injector buildup while optimizing performance, power, smoothness, idle quality and mileage. The problem is that while most of these products have additives that are great for keeping your fuel injectors clean, they don’t do much to clean parts that are already dirty.

Almost every fuel system we’ve seen is dirty, to one extent or another. Read More

One Simple Solution for All Kinds of Diesel Fuel Problems

Rislone® Diesel Fuel System Treatment takes the place of six types of diesel fuel additives.

It’s easier than you think to stop the most common diesel fuel problems dead in their tracks. For common issues like rough running or noisy diesel engines, one bottle of Rislone Diesel Fuel System Treatment (P/N 4740) contains the same amount of additives equal to a bottle of almost every type of diesel fuel additive on the market. This includes ULSD sulfur substitute, injector and complete fuel system cleaner, upper cylinder lubricant, anti-gel cold flow improver, fuel stabilizer and conditioner, and even Cetane booster. With just one product, you can improve the quality of your diesel fuel by increasing its cleaning ability, adding lubrication, removing contaminants, fighting corrosion, and helping to prevent the fuel from gelling and going bad. What could be simpler?


“The process used to reduce the sulfur to make ultra-low-sulfur Diesel (ULSD) also reduces the fuel’s lubricating properties, which leads to a multitude of potential problems that can have a diesel engine running rough or noisy,” says Clay Parks, vice president of development for Rislone. “We made Rislone Diesel Fuel System Treatment so you don’t have go through a lot of products that don’t solve the problem before you find the one that does. Just start – and end – with the all-in-one diesel fuel additive that solves them all.”

Here’s a rundown on the Rislone Diesel Fuel System Treatment additives and the benefits you will see:

  • ULSD (Ultra-Low-Sulfur Diesel) Sulfur Substitute Lubricant. Provides fuel system lubrication to protect the various parts of the engine’s fuel injection system from wear. This reduces noise, increases power and saves fuel.
  • Injector and Complete Fuel System Cleaner. Provides cleanup for coking and ULSD deposits to increase fuel economy, improve power and acceleration, reduce emissions and enhance engine life.
  • UCL (Upper Cylinder Lubricant) Pump and Injector Lubricant. Provides corrosion protection and improves starting and idle.
  • Anti-Gel Cold Flow Improver. Provides up to a 23°F (13°C) reduction in the cold filter plugging point (CFPP) to improve low-temperature performance.
  • Fuel Stabilizer and Conditioner. Helps to stabilize the fuel and improve biodiesel performance.
  • Cetane Booster and Diesel Treatment. Boosts cetane to help reduce black smoke.

Why a Zinc Oil Additive? Because Today’s Motor Oils Are Not Made for Average-Aged U.S. Vehicles

Thankfully, Rislone Oil Supplement, a potent zinc oil additive, can help.

A car of average age today needs more metal protection for its engine than it can get from standard motor oil. That’s because the average age of U.S. vehicles is currently 11.5 years old, according to research firm IHS Automotive, and all vehicles of that age and older need more zinc and phosphorous than current engine oils contain. Rislone® 3X Concentrated Engine Oil Supplement with Zinc Treatment (p/n 4405) provides consumers, technicians and auto parts counter personnel with a golden opportunity to help with these vehicles at any oil change interval.

Environmental Protection Agency emissions regulations led to new engine designs that allowed motor oil manufacturers to significantly reduce the zinc and phosphorus content of motor oil over the last couple of decades. As a result, the oil that’s sold today works fine for new vehicles, but doesn’t meet the needs of more than a third of the cars and light trucks on the road today that are of average age or older.

Rislone 3X Concentrated Engine Oil Supplement with Zinc Treatment is a cost-effective way to help modern motor oils better protect the metal surfaces of older gasoline and diesel engines, safeguarding internal components like pistons, flat tappet camshafts, lifters and the valvetrain. It works with all petroleum-based motor oils including conventional, high mileage and synthetic formulas.

For older vehicles, Rislone 3X Concentrated Engine Oil Supplement with Zinc Treatment offers two ways to protect and lubricate moving parts better then oil alone. The first is high levels of ZDDP (zinc dialkyldithiophosphate) zinc and phosphorus additives. When put under pressure, ZDDP attaches to metal surfaces and becomes a sacrificial wear material, preventing the metal itself from being worn away. Copolymer esters are the second level of protection. They have an attraction for metal surfaces that allow modern oils to hold onto metal surfaces instead of running off as normally happens over time.

“This zinc oil additive is a great performance booster developed to help keep older cars — about a third of the cars on the road today — running properly for years longer,” says Clay Parks, vice president of development for Rislone. “Rislone 3X Concentrated Engine Oil Supplement with Zinc Treatment not only contains the correct amount of ZDDP, the best form of zinc and phosphorus protection available anywhere in the automotive world, it also has the detergents and other lubricity additives important to keeping your customers’ engines clean and lubricated for thousands of miles.”


Rislone 3X Concentrated Engine Oil Supplement with Zinc Treatment reduces friction and wear, especially at start-up, resulting in a cooler-running, longer-lasting engine. This high-performance zinc oil additive also stabilizes the motor oil to prevent viscosity and thermal breakdown. Special additives inhibit corrosion and prevent oil thinning at high temperatures where normal oil fails.

Modern oils have enough zinc to protect moving parts inside newer engines. Rislone 3X Concentrated Engine Oil Supplement with Zinc Treatment is formulated for older vehicles. This includes car and light truck gasoline engines (2004 or older); light-, medium- and heavy-duty diesel engines (2006 and older); 4-stroke marine engines; motorcycle engines (dry clutch only); as well as agricultural, industrial and racing applications. For best protection, Rislone Engine Oil Supplement with Zinc Treatment should be used with every oil change. It should not be sold as a break-in additive.

Rislone 3X Concentrated Engine Oil Supplement with Zinc Treatment is available to distribution in case packs of six 11 oz. bottles. Like all Rislone products, it is made in the U.S.A.

The North American International Auto Show (NAIAS)

The North American International Auto Show (NAIAS) is the kickoff event of the year for automotive manufacturers and their enthusiasts. The auto show held in the heart of Detroit attracted over 800,000 attendees in its nine days of display. The auto makers use shows like the NAIAS to showcase all of their vehicles including a variety of colors, models and a collection of vehicles that won’t hit the market for years. If you’re looking for what the future of cars is going to look like, there is a good chance it was on display at the NAIAS.

What jumped at me was Buick. The company was proud to display their futuristic concept vehicle of the future, a model they’re calling the Avista. The vehicle featured carbon fiber and aluminum detailing as well as a full touch screen across the whole span of the dashboard that would allow the driver and passengers access to the climate control settings, entertainment features and many other accessories. The most interesting fact about this vehicle is that the entire roof is a touch screen made of glass. Now before you get yourself ready to sign the paperwork, they made it very clear this was only a concept vehicle and there aren’t any currently in production. What is the purpose of putting this un-buyable vehicle on display? Because these cars are in our immediate future, and the automakers want you to know what they’re doing. It’s a way they can show technological thought leadership. Going beyond cars of the future, this year FIAT displayed cars of the galaxy with their Storm Trooper car. Star Wars The Force Awakens broke box office records, so it’s no real surprise to find someone pulling in fans at the auto show.

If you’ve ever wondered what the airbags in your vehicle really look like or maybe the inside of your engine? The NAIAS had dozens of displays featuring the parts of your car you never get to see. A company that manufactures airbags had an interesting display featuring a clear car with the different kind of airbags you’ll find in your vehicles. You could also find displays featuring engines, transmissions all the way down to your tires.

Whether you’re an automotive enthusiast or you’re just looking into purchasing a new or new to you vehicle auto shows can be a good resource for information and give you the opportunity to get in the vehicles. The North American International Auto show happens in Detroit, but auto shows happen all over the United States and the world, so stay on the lookout for one in your area.

Warming Up Your Car: Good for You, Bad for Your Engine

Not long ago, Popular Mechanics posted an article about something we tell our customers all the time (and most don’t believe us): warming up your car by letting it idle when cold out certainly helps your car get comfy, but it’s bad for modern engines. In fact, the method that we all use today originated back when engines were carbureted and is completely outmoded today. Says Popular Mechanics:

Warming up your car before driving is a leftover practice from a time when carbureted engines dominated the roads. Carburetors mix gasoline and air to make vaporized fuel to run an engine, but they don’t have sensors that tweak the amount of gasoline when it’s cold out. As a result, you have to let older cars warm up before driving or they will stall out. But it’s been about 30 years since carbureted engines were common in cars.

Today’s cars have computers (ECUs) controlling fuel injected engines, so there’s no concerns about feeding your car the correct fuel/air ratio. The computer handles it all by adding more gas to the mixture when cold, and then tapering the extra gas off to normal levels by the time it reaches 40 degrees Fahrenheit.

But what about today’s cars that have remote start? It’s there for a reason, right? And that reason is to let you warm it up outside while you finish your cup of coffee so you don’t have to get into a freezing car, right?

Well, sort of. That’s great for you, but you should take some precautions for your car if you are going to let it warm up for extended periods in cold weather.

We recommend a simple and inexpensive combination to fight off the negative effects of warming up your car:

  1. Use Rislone Engine Treatment (or Engine Treatment Concentrate) every oil change to reduce startup friction and wear and prevent sludging.
  2. Use Rislone Complete Gasoline Fuel System Treatment to give your engine upper cylinder lubrication and clean fuel injectors.

The best thing about this combo is that both products are proven effective by millions of customers worldwide. Even better? This isn’t a high-maintenance plan. Simply use the Rislone Engine Treatment at every oil change, and use the Rislone Complete Gasoline Fuel System Treatment every 5,000 miles (or 8,000 km) for best results. Affordable, easy and guaranteed to make it easier on your car on those cold winter mornings when you let it idle to warm up.
