Fuel Requirements
  • For optimal performance, use unleaded gasoline which has an octane rating of RON 95/AKI 91 or higher.

Break-In Process
  • By following a few simple precautions for the first 1,000 km (600 miles) you may add to the performance, economy and life of your i30N.
  • Do not race the engine.
  • While driving, keep your engine speed (rpm, or revolutions per minute) within 3,000 rpm.
  • Do not maintain a single speed for long periods of time, either fast or slow. Varying engine speed is needed to properly break-in the engine.
  • Avoid hard stops, except in emergencies, to allow the brakes to seat properly.
  • Do not tow a trailer during the first 2,000 km (1,200 miles) of operation.
  • Do not use Launch Control during the break-in process.

At least one a month:​
  • Check coolant level in the engine coolant reservoir.
  • Check the operation of all exterior lights, including the stop lights, turn signals and hazard warning flashers.
  • Check the inflation pressures of all tires including the spare for tires that are worn, show uneven wear, or are damaged.
  • Check for loose wheel lug nuts.
Twice a year:
  • Check radiator, heater and air conditioning hoses for leaks or damage.
  • Check windshield washer spray and wiper operation. Clean wiper blades with a clean cloth dampened with washer fluid.
  • Check headlamp alignment.
  • Check muffler, exhaust pipes, shields and clamps.
  • Check the seat belts for wear and function
Once a year:
  • Clean body and door drain holes.
  • Lubricate door hinges and hood hinges.
  • Lubricate door and hood locks and latches.
  • Lubricate door rubber weather strips.
  • Check the air conditioning system.
  • Clean the battery and terminals.
  • Check the brake fluid level.

Scheduled Maintenance (Europe):

I: Inspect R: Replace

Tire Pressure


Engine Lubricants


Light Bulbs

Map: 2x W16W​
Room (sunroof): 31mm* festoon (LED)​
Vanity mirror: 2x 31mm* festoon​
Glove box: 1x W5W​
Luggage compartment: 31mm* festoon​
*31mm may be a really snug fit and require some fiddling to get them in, but it'll be better than a loose 28mm.


Rear indicators: 2x PY21W​
Reverse: 2x W16W​

I'm not home so I'll look into all that a bit later. My problem is that I can't be 100% sure what the interior bulb types are, as I think they are different for models with or without sunroof. :rolleyes:

Thread is now open for replies, I don't know what else I can add, all suggestions are welcome! :)
Would like to see the following:

Wheel offsets (18” - 49.5mm, 19” - 55mm)
Wheel weights (18” - ?, 19” - ~13.1kg/28.9lbs)
Wheel+tyre weights (18” - ?, 19”+ Pirelli PZ HN - 23.1kg/50.9lbs)
Wheel lug spacing (5x114.3mm)
Hub bore size (67.1mm)

TB size (60mm?)
Front seat weight (30.1kg/66.4lbs)
Rear seat weight (9kg/19.8lbs)

Spark plugs & gap range
MAP sensor pressure specs
HPFP pressure/flow specs
LPFP pressure/flow specs
Fuel injector pressure/flow specs
ECM information (I think the label was posted elsewhere)
Recirculation/Bypass/Blowoff valve type (diaphragm/piston, push/pull) and flange style (28234-2CTA4 - 4-bolt trapezoidal flange)
Turbo model & specs (TD04-19T?)
-Compressor map
-Compressor inlet size
-Compressor outlet size
-Compressor wheel inducer/exducer sizes
-Turbine inlet style (N/A; exhaust manifold is fused with turbine inlet)
-Turbine outlet size
-Turbine wheel material (assuming inconel)
-Turbine wheel inducer/exducer sizes
-Wastegate spring pressure

I'll add more if other things come to mind. Hopefully the service manual becomes available soon. Not sure if sticky threads are viable here but if so, I vote for stickification. Great work thus far!
