Additives to prevent and solve problems

Bardahl has become famous by it’s extended product line of oil – and fuel additives. It al started in 1939. History was made on the racetrack with Bardahl’s famous Oil Boosters B1 and of course by Miss Bardahl in powerboat races. Bardahl proved that adding an additive did matter.

In general we can dived them in 4 categories:

• Oil additives
• Petrol additives
• Diesel additives
• Cooling system additives

Bardahl has a very extensive range of products that can be added to the oil, fuel and radiator. To find the right product we have an extensive question and answer list drawn up.
