Let’s face it, our trucks aren’t going to last forever. However, we can maintain their health by taking care of them with the correct products. In reality, sometimes there are mechanical failures. That being said, diesel additives are going to fix those. But with the help of the correct additives, you might prolong that life or even fix an issue you’re seeing.

With all the diesel additives available on the store shelves, we spent some time with Liqui Moly‘s head PR guy, Peter Szarafinski to clear up a few things. When additives were brought up, Szarafinski laid it all out there for us. “Additives are chemical tools. When we talk about additives as chemical tools, we have to keep in mind that these tools, like any tool, are suited for a specific purpose. That means they are not suited for every purpose,” Szarafinski says. “When trying to solve a problem chemically, it is obvious that severe mechanical defects cannot be repaired this way. Additives are not miracle potions.”

While understanding that additives can’t repair catastrophic failure, we must cover when to use an additive in your engine. Diesel additives can reach areas in the engine that are otherwise only accessible after a lot of disassembly. For instance, look at fuel injectors. Over time, they can get encrusted with deposits.

Diesel Additives For Fuel Systems

“For example, a side effect of diesel combustion is the formation of deposits on the injector tip. Typically, this is because of poor fuel quality and using the wrong oil,” Szarafinski says. “The more deposits on the injectors, the less efficient the combustion. The result is power loss, increased fuel consumption, and an accelerated build-up of even more deposits.”

What Szarafinski means is that, left untreated, you will reduce the life span of the injectors themselves. Sure, you can pull the injectors and clean them thoroughly, but that would be time-consuming and laborious. It is much easier to simply utilize a good cleaner like Liqui Moly’s Truck Series Complete Diesel System Clean every 1,250 miles.

Diesel fuel is getting more expensive every day. You can delay that trip to the station by using the correct products.

What the “Diesel System Clean” does, is remove existing deposits and prevent new ones from forming. On top of removing and preventing deposits, you’ll see that you’ve restored lost horsepower, improved fuel economy, lowered emissions output, and even increased reliability. After all, you’re maintaining the health of your injectors, which will allow them to work efficiently and to have a longer life.

In fact, similar additives have been used in trucking companies and they’ve saved money by using them. Check out the following image below.

By using fuel cleaner, these trucking companies saved money. Combined, they went from using 9.24 gallons per 62 miles of driving to 8.92 gallons per every 62 miles of driving. That isn’t a huge gain, but add that up in today’s fuel costs and it starts to make sense.

Oil Additives

Since we’re on the subject of additives that can save you money, let’s move on to oil. No matter what oil you use, over time, engines will develop deposits and sludge within the oil circuit. All of the nooks and crannies inside the oil system can clog up and not allow proper flow. If you look at Liqui Moly’s Pro-Line Engine Flush, this can clear these obstructions.

When you’re preparing to do an oil change, you apply the Pro-Line Engine Flush. What the flush does is dissolve all of that sludge and clear out obstructions. Once it has been cleaned, it will all funnel down into the engine oil pan. By then, you’re changing your oil, freeing the pan of old, used oil. Now you can refill the engine with fresh oil and allow it to do its job and work at peak performance.

NOTE: Do not drive the vehicle with the Pro-Line Engine Flush in the engine. The cleaning agents are so strong that they reduce the lubrication, so the engine would suffer from massive wear if you take the truck for a drive.

Adding Pro-Line Engine Flush guarantees proper oil pressure in hydraulically activated systems and ensures proper oil flow after a cold start. It also restores engine performance and reduces exhaust emissions.

Hey, You Dropped Something

One of the most common issues plaguing diesel owners is engine leaks. This inevitably happens when the gasket materials sealing the engine fail. “As trucks get older, the seals and gaskets get brittle — especially if cork is used — and this is the reason you’ll have oil drops on the ground underneath your truck,” Szarafinski says. “Of course, you could just pull the engine and tear it apart and reseal it, right?”

Well, you could, but that would take a long time and cost you new gaskets. Before you go crazy, why not find a diesel additive that can work for you while you’re maintaining your daily duties? Liqui Moly’s Motor Oil Saver is a much easier and cheaper option. Once applied, it takes around 500 miles to take effect. Once it has, it rejuvenates the gaskets in the engine, hopefully stopping the leaks.

We’ve all been there. Wouldn’t your driveway appreciate the attempt at rejuvenating those gaskets and seals?

By design, diesel engines see a lot of internal pressure. With the addition of boost and a slowly clogging crankcase ventilation system, it is possible to overpressurize the cooling system. That is why it is common to see antifreeze leaking out of the radiator on trucks and like everything else, fixing the issue isn’t cheap. Simply put, Liqui Moly’s Radiator Stop Leak is designed to offer an alternative for keeping the truck going without that expense.

“If your truck’s radiator has suffered stone chips and is losing cooling fluids through small cracks, Radiator Stop Leak is a great choice. It is simply added to the cooling fluid. Its tiny plastic particles automatically block these cracks and seal them,” Szarafinski affirms “They are so small, they freely circulate in the system and do not agglomerate where they should not. Radiator Stop Leak may also be added in a preventative manner, so the additive is on guard and immediately seals a crack when it occurs. This helps to increase the truck’s reliability, especially when taking it for a longer trip in regions with little infrastructure.”
