Inside Line: Comma

A few notes about the Nissan Skyline (R32/33/34)

Engine Oil

For this particular series of cars, Nissan lists several specifications of engine oil which should be covered by either Comma Xtech 5W30 or Comma Eurolite 10W40. Always use Comma’s application guide to make sure you get the right product for the vehicle you are servicing.

With the service intervals varying from R32 through to the R34 (in some cases this is just 5000km or 6 months) and the potential for fast road as well as track use, 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.

Brake Fluid

Nissan use one or two specifications for brake fluid for these series of Skyline 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, Nissan specify a change interval of 24 months for these series of Skylines. 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 vapourise 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

Nissan use one or two specifications for power steering fluid for the Skyline and again you can rely on Comma’s online application guide to identify which product is suitable for the vehicle you are servicing.

Coolant

Nissan use one or two specifications for coolant for the Skyline covered by Xstream G30 and again you can rely on Comma’s online application guide to identify the correct product for the vehicle you are servicing.

Transmission

For these series of Skyline, Nissan use a range of transmissions that includes manual and automatic as well as two and four wheel drive, which results in various specifications for the gearbox, differentials and transfer box. 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.
