Volkswagen Golf Owners Manual: Bioethanol (Ethylalcohol)

First read and observe the introductory information and safety warnings 

Bioethanol E85 consists of 15% petrol (RON 95) and 85% bioethanol (ethylalcohol). Bioethanol E85 normally contains a red dye for identification.

When using the MultiFuel engine with bioethanol, the fuel consumption may rise by approximately one third in comparison to petrol, but the CO₂ emissions remain below those measured when petrol is used exclusively.

Starting the engine at low outside temperatures

Bioethanol has poor cold-starting properties and it is not easy to start the engine at low temperatures. At outside temperatures of below -10°C (+14°F), the engine should be preheated (  ) or the quantity of petrol (RON 95) in the mix should be increased.

NOTICE

• Before parking the vehicle for an extended period, fill the tank with fuel with a high percentage of petrol. Bioethanol E85 can contain a small amount of contaminants that may cause corrosion.

• Volkswagen recommends that you fill the tank with petrol every 15,000 km to reduce the contaminants in the engine deposited by bioethanol E85.
