Comma EXT Fully Synthetic Central Hydraulic Fluid

Modern vehicles would not be able to operate without the use of some hydraulic systems, for example; their levelling systems, brakes and power steering. Regular replacements at specified intervals which are carried out by the manufacture or a skilled mechanic are essential and can help to increase the life of your hydraulic operated parts. Although to also ensure longevity of these vehicle components you will need to keep the hydraulic fluid topped up to its optimum level at all times.

The EXT Fully Synthetic is a special synthetic-based hydraulic fluid from the Comma range, a world-class manufacturer and supplier of automotive lubricants.
