APPLICATIONS

  • Complies with the FIA and FIM 2002 regulations.
  • Especially blended for 4-stroke racing engines running at high rpm.
  • Thanks to its original blend and its quite high octane ratings, ELF LM®S can be used in a wide range of applications including both natural aspirated (atmospheric) and turbo-charged engines.
  • Typical applications : 24H LE MANS (from which the name of this fuel is coming thanks to the allowance of Le Mans Organisation : used for both 24H endurance races of cars and motorbikes), GT, F3, … Rallies.
  • It is to be mentioned that this fuel is considering the environmental purposes as a major concern and have especially extremely low contents of sulphur and benzene.

RECOMMENDATIONS

  • Air/Fuel ratio needs to be re-tuned according to the relatively high density of ELF LM®S compared to the average value of commercial fuels. As a consequence it is generally necessary to reduce gasoline flows for optimum results (usually best equivalent air/fuel ratios are in the range of 1.10 to 1.15 for atmospheric engines and around 1.20 for supercharged engines). Ignition setting should also be re-tuned in order to reach optimum performances.
  • In order to maintain the original properties, and according to Health and Safety regulations of commercial fuels, this gasoline shall be handled and stored in a cool place and always maintained in tightly shut drums.
