No new engines were used at the Monaco, Hungarian and Singapore Grands Prix
* It was reported at the end of FP3 US GP that all drivers had taken up their 8 engine allocation for this season. Kobayashi's new engine at this event did not incur a penalty suggesting that his earlier data is inaccurate

Using additional engines incurs a ten place starting grid penalty at the first race that each additional engine is used, see regulations tab for detailed overview of rules. Key: Race at which each engine was first used, subsequent races may return to earlier engines.

Engine and Gearbox Regulations 

Relevant 2012 Engine Regulations:

28.4
a) Each driver may use no more than eight engines during a Championship season. Should a driver use more than eight engines he will drop ten places on the starting grid at the first Event during which each additional engine is used. If two such additional engines are used during a single Event the driver concerned will drop ten places on the starting grid at that Event and at the following Event. An engine will be deemed to have been used once the car's timing transponder has shown that it has left the pit lane.
b) If a driver is replaced at any time during the Championship season his replacement will be deemed to be the original driver for the purposes of assessing engine usage.
c) After consultation with the relevant engine supplier the FIA will attach seals to each engine prior to it being used for the first time at an Event in order to ensure that no significant moving parts can be rebuilt or replaced. Within two hours of the end of the post race parc fermé exhaust blanking plates (with one 10mm diameter inspection hole per cylinder) and further seals will be applied to all used engines in order to ensure that these engines cannot be run between Events. Upon request to the FIA these additional seals will be removed after the start of initial scrutineering at the next Event at which the engines are required. All such engines must remain within the team's designated garage area when not fitted to a car and may not be started at any time during an Event other than when fitted to a car eligible to participate in the Event.
d) If any of the FIA seals are damaged or removed from an engine after it has been used for the first time that engine may not be used again unless they were removed under FIA supervision.
e) If an engine is changed in accordance with Article 34.1 (in post qualifying parc fermé) the engine which was replaced may not be used during any future qualifying session or race with the exception of the last Event of the Championship.

Relevant 2012 Gearbox Regulations:

28.6 For the purposes of this Article only, an Event will be deemed to comprise P3, the qualifying practice session and the race.
a) Each driver may use no more than one gearbox for five consecutive Events in which his team competes. Should a driver use a replacement gearbox he will drop five places on the starting grid at that Event and an additional five places each time a further gearbox is used. Any replacement gearbox must be fitted with the same gear ratios that were declared under d) below and will only be required to complete the remainder of the Event in question. Any change to the gear ratios declared under d) below will incur a further five grid place penalty. In either case a new five race sequence may start at the following Event. Unless the driver fails to finish the race (or is unable to start the race for reasons other than a penalty imposed by the stewards) the gearbox fitted to the car at the end of the Event must remain in it for the remainder of the five race sequence. Any driver who failed to finish the race at the first, second, third or fourth of the five Events for reasons which the technical delegate accepts as being beyond the control of the team or driver, may start the following Event with a different gearbox without a penalty being incurred. A gearbox will be deemed to have been used once the car's timing transponder has shown that it has left the pit lane.
b) If a driver is replaced after the first, second, third or fourth Event of a five Event period, having finished the first, second, third or fourth Events, the replacement driver must use the gearbox which the original driver had been using.
c) After consultation with the relevant team the FIA will attach seals to each gearbox in order to ensure that no moving parts, other than those specifically permitted under d) below, can be rebuilt or replaced.
d) At each Event seals may be broken once, under supervision and at any time prior to the second day of practice, for the sole purpose of changing gear ratios and dog rings (excluding final drives or reduction gears). Competitors must inform the FIA technical delegate which ratios they intend to fit no later than two hours after the end of P2. However, one additional change of ratios and dog rings will be permitted if a gearbox change is necessary on the first day of practice before the end of P2. Gear ratios and dog rings (excluding final drives or reduction gears) may also be changed under supervision for others of identical specification at any time during an Event provided the FIA technical delegate is satisfied there is evident physical damage to the parts in question and that such changes are not being carried out on a systematic basis.
e) Other than under d) above, a replacement gearbox will also be deemed to have been used if any of the FIA seals are damaged or removed from the original gearbox after it has been used for the first time.
