The Golden Rule
- Always choose the fuel additive that matches your engine type (gasoline or diesel).
- Oil additives and engine flush are suitable for gasoline and diesel engines—providing comprehensive care from tank to tailpipe.
Gasoline Vehicles (Spark-Ignition Engines)
Typical Symptoms
- Jerking during acceleration, rough idle, or unstable idling speed
- Noticeable increase in fuel consumption and power loss despite unchanged driving habits
- General starting problems and engine stuttering
Our Recommendation
- EUROSOL Gasoline System: Every 6 months, or when heavy contamination or problems occur, add to the tank every third fill. The additive dissolves resins in carburetors and injectors, binds moisture, and ensures a clean spray pattern—resulting in optimized fuel economy and improved emissions.
- EUROSOL Oil System: Before every oil change, add to the used engine oil and run the engine for 10 minutes; dissolves coking on piston rings, cleans lifters, and clears all oil passages.
- EUROSOL High-Performance Oil Additive: Add one 400 ml bottle directly to fresh engine oil. High-pressure lubricant components form a protective film that reduces friction and wear.

Diesel Vehicles
Typical Symptoms
- Knocking engine operation, black smoke, or EGR valve coking
- Frequent limp-home mode due to a clogged DPF
- Power loss under full load and increased fuel consumption
- Starting problems at low temperatures due to paraffin wax precipitation
Our Recommendation
- EUROSOL Diesel System: Every 3–6 months, or when heavy contamination or problems occur, add to the tank every third fill. It removes tank deposits, cleans the entire fuel system and injectors, dissolves coking in the EGR valve, and regenerates the particulate filter—boosting cetane number and producing a more uniform spray pattern.
- EUROSOL Oil System: Before every oil change, add to the used engine oil and run the engine for 10 minutes; dissolves coking on piston rings, cleans lifters, and clears all oil passages.
- EUROSOL High-Performance Oil Additive: Add one 400 ml bottle directly to fresh engine oil. High-pressure lubricant components form a protective film that reduces friction and wear.

Oil change coming up? What to do?
- Add EUROSOL Oil System to the old engine oil and run the engine for 10 minutes.
- Perform the oil and filter change according to the manufacturer’s instructions.
- Add one 400 ml bottle of EUROSOL High-Performance Oil to the new engine oil.
- Result: Fresh oil in a clean engine with optimal wear protection.
