Liqui Moly Cera Tec Friction Modifier
Key Features:
- Mixable with all commercially available motor oils
- Stable even under high thermal and dynamic permanent loads
- No deposits and absolutely compatible with all commonly used filter systems
- Resists extremely high and low temperatures
Liqui Moly Cera Tec Friction Modifier is a powerful product used to reduce wear inside of an engine. It works by changing the composition of the engine’s oil, making it smoother and easier to pump, as well as changing the composition of wear particles in the engine. It is especially useful for older cars that have been driven a long time or used regularly (such as those found on construction sites).
However, due to its price and cost effectiveness, many users recommend it for newer car use as well.
Liqui Moly Cera Tec Friction Modifier works by converting the molecules within oil to make them smoother and more slippery; therefore allowing parts of an engine’s internal combustion process to flow with less resistance. This makes pistons move faster and more freely along cylinders, increasing horsepower while decreasing fuel consumption/emissions at the same time.
What is Oil Additive for Diesel Engine Cars?
Oil additive for diesel engine cars is a chemical concoction that provides lubrication to moving parts of an engine, decreasing friction and corrosion. Lubricants are used to reduce the metal-to-metal contact in engines by providing a barrier between two surfaces that are rubbing on each other.
Since diesel engines run hotter than gasoline engines, they need better quality oil that can stand up to the additional heat without burning off quickly. Oil additives extend the life of your car’s motor oil, so you don’t have to change it as frequently. If you drive your diesel powered vehicle under normal driving conditions with no unusual vibrations or noises, then automatic transmission fluid additive may be all you need for complete maintenance of your engine.
But if your car emits smoke out of the exhaust, if it makes unusual noises or vibrations, or if your car burns through oil quickly, then you might need to use a cleaner in addition to an engine oil additive. Cleaners help unclog oil passageways in engines that are filled with carbon residue.
The Function of Oil Additive
An oil additive is an added substance that changes the chemical composition of lubricating oils or provides additional properties for engine lubrication. The benefits additive provide include improved stability, corrosion protection, viscosity control, wear protection and friction reduction.
Oil additives are used to help control the foaming in crankcase oil caused by heat and pressure. This reduces the amount of oil that mixes with air, which causes more heat to be generated. A number of additives are designed specifically for controlling foam within engine oils.
The best oil additive will have some type of extreme pressure agent added, so it is best used in racing car engines under high levels of stress. It will also increase the oil’s reserve alkalinity.
There are additives available for both diesel and gasoline engines, so the best oil additive will be designed to work with each type of engine. Some additives will increase the viscosity of oil or help it flow at higher temperatures.
If you’re looking to buy the best oil additive, look for one that reduces viscosity breakdown and improves fuel economy. The best oil additive will also act as a metal conditioner for the engine. Oil additives are commonly used in many lubricants, solvents, fuels, diesel engine oils and hydraulic fluids to improve their performance.
The benefits of using an oil additive include reduced volatility in gasoline, increased engine power, improved lubrication and better protection against wear. It is important that you use the appropriate oil additive for your specific type of engine to prevent damage.
Oil additives are available in a variety of colors, strengths and fragrances depending on user preference.

Oil Additive for Diesel Engine Cars – Buying Guide
Diesel cars have a few things going for them, but their engines tend to be less efficient than gasoline-powered ones. One way to offset this is a diesel oil additive which you add to your fuel tank. It’s an extra expense, so you’ll need to decide if the benefits are worth the investment.
In this article we’ll discuss diesel engine oil additives and the advantages they offer.
A diesel oil additive is a chemical or compound that you add to your car’s fuel tank at regular intervals. It mixes with the fuel and boosts efficiency in your diesel engine. Normally it helps clean out any gunk that accumulates in your fuel system. This gunk can clog up small passageways and impede the movement of air, which reduces power.
Because this additive is added to the fuel, it’s more concentrated than an oil that’s simply burned in your car’s engine .
As a result, you may only need to add it once every few months instead of once or twice a week.
Why using Oil Additives in Diesel Engines?
Diesel engines are highly efficient, but there is one big disadvantage compared to gasoline or compressed natural gas (CNG) engines. The problem with diesel cars is the emission of black smoke which usually indicates poor combustion. Many people think that diesels produce more harmful gases than their gasoline counterparts because they are not equipped with a catalytic converter. However, the main reason for this smoky emission lies in poorly adjusted injection or wrong choice of fuel additives for diesel engine cars. There are many arguments whether adding oil additives for diesel engines can improve vehicle performance and solve accompanying problems like reduced power output, reduced fuel economy, increased emissions levels and so on. The article will try to resolve all these issues related to using oil additives in your car’s diesel engine.
In order to understand how oil additives for diesel engines work, you should first check the chemical formula of diesel fuel. Diesel fuel is a kind of liquid petroleum which includes a broad spectrum of hydrocarbon compounds containing carbon and hydrogen only. The American Petroleum Institute (API) groups these hydrocarbons into five categories: gas oils, gas-oils equivalent, distillates, distillate equivalents and residuum. Gasoline engine cars use gasoline as a fuel that contains small amounts of additives such as lead or benzene that serve as anti-knocking agents and improve efficiency. As we mentioned before, the main problem with diesel cars is their emission of black smoke which results from incomplete combustion because there are no additives in this type of fuel.
Oil additives for diesel engines contain detergents and/or dispersants that help fight soot, carbon and also other contaminants present in the engine oil as residues of combustion which cause engine wearing and clogging. These additives reduce harmful particles emission from exhaust gases by keeping the engine clean. Few types of car oil additives include polyisobutylene, alkyl-benzene sulfonate, polyether amine and others.
Combined with oil additives for diesel engines or used alone, synthetic motor oil is an indispensable product in order to improve vehicle power output and fuel economy. It is compatible with all types of fuels (diesel fuel, gasoline fuel) and can be used in all types of engines.
Oil additives for diesel cars and motor oil combined with these additives provide great benefits in terms of engine wear and clogging prevention, emission reduction and power output improvement. Just make sure that you choose high-quality products complying with API specifications and enjoy clean driving!
How to Choose the Right Oil Additive?
In order to choose the best oil additive for diesel engine cars, it is necessary to know about its composition and formula. In general, there are two types of these additives: chemical and bio-degradable type. Chemical ones contain ingredients such as phosphorous compounds which can damage catalytic converters . It should therefore be a priority in choosing the right additive.
Biodiesel oil additives are now becoming popular among car users because they can work as good as these chemical ones but without any side effects to drivers and their cars. It is necessary to check with automobile manufacturers, however, whether biodiesel additives will not damage the engine’s performance or parts over time.
Oil Additive Change Intervals for Diesel Engines
Although it is generally accepted that regular oil and filter changes are vital for gasoline engines in order to maintain good performance, many diesel engine owners tend to procrastinate on oil changes due to the misconception that diesel engines can run forever without an oil change.
This is very dangerous for your vehicle, as the components in diesel engines are far more susceptible to wear and tear than gasoline engines.
Oil change intervals for diesel engines are typically determined by mileage, rather than time or usage. However, there are other factors that affect the ideal oil change interval for a diesel engine, including driving conditions and how well you maintain your engine.
