The light at the end of the tunnel is visible. Spring is almost here, and that means no more need for anti-gelling agents for your fuel or other winter-specific tasks like plugging in your truck at night. That’s great news, but it does mean that a few things might be needed for your truck to be ready for the warm weather.
I am talking about spring cleaning for your diesel. We all have plans of many hundred thousand miles being driven on our trucks, but if we don’t take care of them, that will never happen. So, we reached out to the people at Liqui Moly to see if they have any thoughts about what you can do for your truck now that spring is here. Luckily, they have a complete Truck Series line of additives that are perfect for keeping your truck in perfect running condition.
Fuel System Prep So Your Truck Is Ready
Everyone knows that a clean fuel system equals a great running truck. So, why not use a recommended additive to ensure a clean fuel system? According to Liqui Moly, the Truck Series Complete Diesel System Cleaner is perfect for the internal spring cleaning of the diesel engine. It removes deposits in the injection system and combustion chamber and prevents them from forming again. Clean engines consume less fuel and reduce pollutant emissions.

This fuel additive cleans and maintains all injection system components and prevents the nozzle needles from seizing and gumming up. It also increases the cetane number and of the fuel which improves the ignitability of the diesel fuel. Engine System Cleaner Diesel ensures smooth engine running and protects the entire fuel system against corrosion and wear. This leads to the original performance of the engine and low exhaust gas values.
- Prevents the build-up of deposits
 - Prevents seizing and injector gumming
 - Protects injection system components from wear
 - Guarantees optimum combustion
 - Suitable for all diesel engines, including common rail and pumped-jet
 - Removes deposits from the entire fuel system
 

Once you have given the fuel system a good cleaning, it’s time to maintain it. The Truck Series Diesel Performance and Protectant is a combination of additives designed to clean and maintain a diesel fuel system. It prevents corrosion, and increases lubrication, thus reducing fuel pump and injector wear. It also increases cetane value for improved engine performance, easier starting, and lower emissions. Regular use keeps the fuel system in perfect working order.
- 
- removes undesirable residues
 - increases cetane number
 - increases smooth operation
 - reduces pollutant emissions
 - protects expensive components against wear and corrosion
 - prevents the build-up of deposits
 
 
One 500 ml container is sufficient for 7 to 40 gallons of diesel. The effect lasts up to 1,200 miles.
Internal Cleaning
Does your spring-cleaning routine involve an oil change? If so, have you ever considered cleaning the inside of your engine before you drain the old oil? We all know it’s a good idea to run the engine for a few minutes before draining the oil, so when you do, why not add Pro-Line Engine Flush to the old oil to help clean the internal areas of your engine and drain the dirt out with the old oil.
Pro-Line Engine Flush is a highly effective formulation designed for the quick and safe removal of deposits in an engine before an oil change. Simply add the appropriate amount to your engine oil, start the truck and let it run for a few minutes, and then drain.

Cleaning the engine with Pro-Line Engine Flush minimizes oil consumption, guarantees proper oil pressure in hydraulically activated systems, and ensures proper oil flow after a cold start. This helps keep your truck ready for anything. It is designed for all four-stroke engines, with or without turbochargers. It is also safe for use with catalytic converters and particulate filters (GPF/DPF) and is compatible with most commercially available motor oils. A full can is used for 0.8 gal. to 1.3 gallons of motor oil.
Add Pro-Line Engine Flush to the engine oil at operating temperature before changing the oil. After adding the product allow the engine to idle for 10 to 15 minutes depending on the degree of contamination. Then change the oil and the filter.
DPF Protection
Truck Series DPF Protector reduces the formation of soot in the engine during the combustion process. This will help improve engine performance and emissions control as it reduces clogging of the DPF caused by soot as a combustion byproduct. Simply add to diesel fuel as it is specially designed for trucks and commercial motor vehicles, tractors, construction machinery, and stationary engines. For best results and long-term effects, add DPF protector every 1.200 miles. One full can is sufficient for treating 14 to 30 gallons of diesel fuel.

Is Your Truck Ready For Internal Protection
If your truck has a lot of miles on it, maybe it’s time to consider adding Liqui Moly’s Truck Series Oil Treatment. According to Liqui Moly, adding it to your high-mileage engine ensures immediate friction and wear reduction, adds an extremely protective and pressure-resistant boundary layer with low friction, and lubricates moving parts during cold starts to prevent damage from lack of oil. It also contributes to lower fuel consumption, longer engine life, and less noise. It is specially designed for older engine designs with or without a turbocharger. Regular use keeps the engine in perfect working order to keep your truck ready.
Liqui Moly’s Oil Treatment is designed for use in all four-stroke gasoline and diesel engines, with or without turbochargers. Compatible with most commercially available motor oils. Safe for use with catalytic converters and particulate filters (GPF / DPF). One 500 ml can is sufficient for one to 2-1/2 gallons of motor oil.
Spring is here, and I hope you have your truck ready for the hot-weathered work you have planned for it.
