29. FUEL: Only petroleum-based unleaded or leaded gasoline
as defi ned by the American Society of Testing and Materials
(ASTM) is permitted. The Yamaha Motor Corp. recommends
the use of 89 octane unleaded gasoline in all FJ1200/XJR1200/
XJR1250(sealed) engines. Higher octane fuels can cause higher
operating temperatures and reduce the running life of your
engine. The only oxygenates permitted are MTBE and ethanol
alcohol at a maximum amount of 4% by volume. INEX
reserves the right to require all cars use the same brand and
designated grades of gasoline in a given event.
Specifi c Gravity - The specifi c gravity must read from .710
to .760 at 60 degrees Fahrenheit, factored by a specifi c
gravity temperature chart.
Laboratory Testing - INEX has the ability to conduct
laboratory analysis of fuels. Samples for lab analysis may
be taken from a competitor’s fuel tank at any time at the
discretion of the INEX Technical Inspector.
The specifi c elements which will be searched for include:
propylene oxide, alcohols (all types), aldehydes, aminodiphenyl,
benzene (in excess of EPA limit), benzidine, beryllium
compounds, bromine compounds, butadienes, chlorinated
compounds, chromates, dioxanes, ethyl acrylate, ethylene oxide,
hydrazine compounds, methylene dianailine, naphthylamine,
nitrogen compounds (nitromethane, et al.), styrenes, toluidine
and xylidine. Also added to this list will be substances deemed
to exceed the Threshold Limit Values (TLV) or Biological
Exposure Indicies (BEI) as listed by the American Conference
of Governmental Industrial Hygienists (ACGIH).
Penalty for Fuel Rule Violations - Any competitor (driver and/or
owner) caught using any of the illegal fuel additives as previously
mentioned is subject to a minimum 60 day suspension from the
date of the test results. Suspensions will be determined by INEX
based on the chemical composition of the additive in question.
30. “LEGAL†FUEL ADDITIVES: Lubrication or knock
suppression additives are permitted, provided the resulting
mixture meets the specifi c gravity, lab analysis requirements,
etc. described in rule #29 “Fuel.â€
