Gulf Antifreeze XLL is an Extended Life concentrate based on Mono Ethylene Glycol (MEG) and specially designed corrosion inhibitors to provide protection against frost and corrosion. It needs to be mixed with appropriate amount of water for using as cooling and heat transfer fluid in internal combustion engines. It is free from potentially harmful additives such as nitrites, amines, borate and phosphates and hence it contributes to a safer environment. It is neutral towards gaskets, hoses and provides good resistance against foam.
Features & Benefits
It is extended life coolant based on virtually non depleting synergistic combination of corrosion inhibitors.
It is having high boiling point which decreases the risk of overheating of Antifreeze.
It has as improved hard water stability as it does not contain silicates and other mineral salts.
It is compatible with elastomers used by most of the European OEMs.
It prevents formation of deposits and scale on the surfaces and also compatible with other MEG based antifreeze.
It is suitable for mixed fleet
It is recommended to be used at least 33% dosage of Gulf Antifreeze XLL in 67% water. For enhanced protection, 50% of concentrate in 50% of water is recommended.
It is recommended for use in cooling systems of all types of liquid cooled hi-tech automotive engines where such types of coolants are used. (Please refer OEM manual for recommended
It is particularly recommended where high temperature aluminum protection is important.
