Inside Line: Comma

A few notes about the VW Golf Mk VI (2008 – 2013)

Engine Oil

For this particular series of Golf, VW lists several specifications for engine oil which should be covered by Comma Prolife 5W30 or Comma Syner-G 5W40.

Most of the engines in this series of Golf have quite small sumps – the 1.4 TSI for example has a 3.6-litre capacity. With the normal service interval of around 9000 miles and the extended service of around 18,500 miles, oil top up between services can be critical. Supplying the customer with a top up pack and reminding them that they should be checking the engine oil regularly (see handbook for guidance) might also be prudent here particularly if you have noticed that the oil needed topping up when it was brought in. A quick check before you change might be a good way of reinforcing the importance of top up to the customer. Combined with longer service intervals and the increased use of sensitive components like turbochargers, a smaller sump size makes checking your oil more critical than ever before.

Brake Fluid

VW use one of two specifications for brake fluid for this series of Golf and again you can rely on Comma’s online application guide to identify which product is suitable for the vehicle you are servicing.

Most people don’t think of brake fluid as a service item however, as with many manufacturers, VW specify a change interval of 24-months for this series of Golf. Brake fluid degrades over time by absorbing water from the atmosphere, which lowers its boiling point. Boiling point is a critical factor in brake fluid performance because of the amount of heat generated during braking. If the boiling point of the fluid is too low then continuous or hard braking may cause the brake fluid to vaporize, which in turn can result in a loss of hydraulic pressure within the system. The message here is that brake fluid is a safety critical item so check and change when specified – don’t assume that it will just be OK.

Power Steering Fluid

VW used an electric system for this series of Golf and again you can rely on Comma’s online application guide available to verify that no product is recommended.


VW use one specification for coolant for this series of Golf which should be covered by Xstream G40.


For this particular series of Golf, VW use a range of transmissions that includes manual and automatic as wheel as an optional four-wheel drive system, which results in various specifications. As well as the different fluid requirements, change intervals and capacities will vary depending on the type of transmission so we would advise you to consult the handbook to ensure that you get the right product for the vehicle you are servicing.
