Additives & repair

Just like the exterior and interior of your car, the car's engine and cooling system needs now and then a good cleaning. Cleaning the inside of the engine can be difficult and is often expensive at your local garage. However, with fuel additives, you can do it yourself. Additives mix with liquids such as fuel or coolant, gradually travel through your car. The car is then cleaned from the inside out, and dirt and deposits are removed. Ultimately, this results in better performance, fewer emissions and more efficient fuel consumption. At Winparts you will find products as diesel additivesfuel injector cleanersoctane boostersfuel stabilizers and more from brands such as Liqui MolyWynnsEurol and Lindemann.
