ARTICLE 16: FUEL AND ENGINE OIL
- Basic principles
- Fuel and engine oil, depending on the type of engine, don’t have any restrictions in terms of technology.
The use of fuels that are composed of compounds is accepted, as long as the fuel is not dangerous for people operating with the car, explosive and the environmental targets in terms of CO2/Km are respected.
Chemicals can be mixed with fuels as oxidants as long as all the above conditions are also respected. - The function of an engine oil is to lubricate moving parts, to improve the overall efficiency of the engine by reducing friction and to reduce wear.
It also cleans, inhibits corrosion, improves sealing, and cools the engine by carrying heat away from moving parts.
Engine oils could also enhance the properties of the fuel or energize the combustion, as long as this property is compliant with all other rules included in the technical rules. - All Competitors must be in possession of a Material Safety Data Sheet for each type of fuel or engine oil used.
This sheet must be made out in accordance with EC Directive 93/112/EEC and all information contained there always available at any point during the season and during a Competition. - At the end of a race, the fuel and engine oil that are nor used during the event and the sampling activity at the end of the race must be recycled.
- All fuel and engine oil specs must be presented 1 month before the first race of the season during the safety assessment of the car for FIA approval.
Any change in the formulation during the season will need testing from FIA before being used on track.
Testing requirements are:- Two separate five litre samples, in suitable containers, must be submitted to the FIA for analysis and approval.
- The fuel must be shown to be compatible with the fuel bladder and seal materials used by all teams that will be using the fuel by passing the tests specified in The Appendix to the Technical and Sporting Regulations.
- No fuel may be used in a Competition without the prior written approval of the FIA.
- Fuel and engine oil, depending on the type of engine, don’t have any restrictions in terms of technology.
- Fuel sampling and testing at a Competition
All samples will be taken in accordance with the FIA Formula One fuel sampling procedure. - Engine oil approval
- Before any engine oil may be used in the Formula One Championship, two separate one-litre samples, in suitable containers, must be submitted to the FIA for analysis and approval.
- No engine oil may be used in a Competition without the prior written approval of the FIA.
- In addition to the engine oils approved for use in a Competition, one type of dyno engine oil may be approved by the FIA.
- Sampling and testing at a Competition
- Each Competitor must declare, prior to every Competition, which oil will be used in each of their engines during the Competition.
- For reference purposes, before any oil may be used at a Competition, a sample must be submitted to the FIA together with the oil reference number.
- Engine oil samples taken during a Competition will be checked for conformity by using a Fourier transform infrared (FTIR) technique, which will compare the sample taken with that submitted at the start of the Competition. Samples which differ from the reference engine oil in a manner consistent with fuel dilution, engine fluids contamination and oil ageing as a result of normal engine operation, will be considered to conform.
Samples which differ from the reference engine oil in a manner consistent with the mixing with other engine oils, which have been approved by the FIA for use by the team at a Competition, will be deemed to comply, provided that the adulterant oils are in total present at no more than 10% in the sample. This tolerance will also be applicable for the mixing with the approved dyno engine oil but only for a new engine during the competition at which it is first used.
However, the FIA retains the right to subject the oil sample to further testing at an FIA approved laboratory.
- Competitors can choose different oil and fuel suppliers as long as the 2 fluids or compounds are proven compatible.
