## Long description

Bardahl Multi Additiv 5-i-1 500 ml is an engine additive formulated to support cleaner operation and improved protection for petrol and diesel engines. The 500 ml concentrate is intended to be added to the fuel or oil system according to manufacturer guidance, with a multifunctional composition that addresses lubrication, cleaning of deposits, corrosion protection, fuel system maintenance and reduction of mechanical noise. The product is suitable for routine maintenance to help preserve engine components and assist in maintaining consistent performance.
Advantages
The formula combines lubrication enhancement with detergent action to reduce carbon and varnish deposits on injectors, valves and combustion chambers. Corrosion inhibitors protect metal parts exposed to fuel and combustion by-products, while additives designed for the fuel system help maintain injector and carburettor function. The noise-reducing components support smoother mechanical operation and can help reduce rattling or knocking related to friction and deposit build-up.
Suitable for
 Petrol engines in passenger cars for cleaner injectors and combustion chambers
 Diesel engines requiring fuel system cleaning and improved lubrication
 Older vehicles with deposit build-up on valves and injectors
 Vehicles undergoing routine maintenance to help prevent corrosion and reduce mechanical noise

How to use
Use the additive according to the vehicle or engine manufacturer’s instructions and the dosage indicated on the product label.

For oil-system applications, add the specified dose to the engine oil while warm and follow any required oil-change intervals. Avoid exceeding the recommended dose and ensure compatibility with existing fuel or oil type.
