From the Bentley:
"For maximum engine performance, unleaded fuel with an octaine[sic]
rating of 91 RON, which corresponds to an anti-knock index (AKI) of
87, is recommended."
Also: "Regular fuels have an octane rating ranging from 91 to 95 RON
(Research Octane Number) or 87 to 91 AKI.
(bold)Do not use any fuel with octane ratings lower than 91 RON or 87
AKI.(endbold)"
(Then again, I also noticed that this book would be illegal to sell in
Iowa, for the following paragraph:
"Gasoline containing alcohol is available at gas stations in some
areas. The gas pump may not be labeled to identify that alcohol is
present in the gasoline. If it is labeled, it may not identify what
amount and type(s) of alcohol are used. We recommend you use q uality
gasoline that is NOT blended with alcohol. The use of fuel containing
alcohol can cause loss of fuel economy and driveability and
performance problems. If these problems are experienced, we recommend
you to switch to another brand of gasoline."
In Iowa, it's against the law for any mechanic to tell a customer that
their engine problems are caused by alcohol-containing gasoline.)
Cheers,
