Inside Line: Comma


A few notes about the Peugeot 207 (to 2012):

Engine Oil

• Peugeot tend to favour a product like Comma Protech 5W30 for most of their vehicles however the very latest engines may carry different recommendations.

• Some of the engines options fitted in the Peugeot 207 have quite small sumps – the 1.6HDI for example has a 3.8L sump with a further 0.5L held in the filter.

• 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

• In the main, Peugeot specify a conventional DOT 4 brake fluid however it’s always worth checking before fitting any product.

• Most people don’t think of brake fluid as a service item however, as with many manufacturers, Peugeot specify a change interval of 24months for the 207. 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 vaporise 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

Peugeot use an electric power steering system for the 207, so it does not use a hydraulic fluid here.


Peugeot use an OAT based coolant for all of the 207 range for which Comma recommend Xstream G30. The OEM factory fill product for this series of vehicles is in fact blue in colour rather than red however the colour in coolant is generally just a dye which is often added to help distinguish an OEM part number from after-market alternatives. As with any other fluid the important thing is the specification.


For this particular model, Peugeot use a range of transmissions that includes manual, conventional automatic and automated manual each with a different fluid recommendation. As well as the differing 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.
