I was wondering whether anybody has seen any relationship between their LC MPG and the different octanes of gas. Thanks for sharing the info.

Russ in California said:87 octane is bad enough $2.47

Fuel type
Your vehicle must use only unleaded gasoline.
To help prevent gas station mix–ups, your Lexus has a
smaller fuel tank opening. The special nozzle on pumps with
unleaded fuel will fit it, but the larger nozzle on pumps with
leaded gas will not.
NOTICE
Do not use leaded gasoline. Use of leaded gasoline
will cause the three–way catalytic converter to lose
its effectiveness and the emission control system to
function improperly. Also, this can increase
maintenance costs.
Octane number
Select Research Octane Number 91 (Octane Rating 87)
or higher.
Use of unleaded fuel with an octane number or rating lower
than stated above will cause persistent heavy knocking. If
severe, this will lead to engine damage.
If your engine knocks...
If you detect heavy knocking even when using the
recommended fuel, or if you hear steady knocking while
holding a steady speed on level roads, consult your Lexus
dealer.However, now and then, you may notice light knocking for a
short time while accelerating or driving up hills. This is no
cause for concern.
Gasolines containing detergent additives
Lexus recommends use of gasolines that contain
detergent additives to avoid build–up of engine
deposits.
For further details, ask your Lexus dealer or a local gasoline
retailer.
Gasolines containing MTBE
Gasolines that contain MTBE (Methyl Tertiary–Butyl
Ether) are available in the market. If you use a gasoline
mixed with MTBE, make certain that it does not contain
more than 15% of MTBE.
If the use of gasolines containing MTBE causes poor
driveability and/or poor fuel economy, you should stop using
them.
Gasolines containing alcohol
Gasohol is a mixture of gasoline and ethanol. If you use
gasohol in your Lexus, be sure that it is unleaded, has
an octane rating no lower than 87 and does not contain
more than 10% ethanol. Lexus does not recommend the
use of gasolines containing methanol.
If you use gasoline containing methanol, use only gasoline
meeting the requirements above and also containing less
than 5% methanol with cosolvents and corrosion inhibitors
for methanol.
NOTICE
Do not use gasohol other than stated above. It will
cause fuel system damage or vehicle performance
problems.
If driveability problems are encountered (poor hot
starting, vaporizing, engine knock, etc.),
discontinue its use.
Take care not to spill gasohol during refueling.
Gasohol may cause paint damage.
Fuel tank capacity
95 L (25.1 gal., 20.9 Imp. gal.)
lurker said:"my 96 says 87 or higher, I took that to mean use what you want as logn as it is 87 or above ?"
Yes it's alright to use octane higher than 87 as long as it's coming out of the gas station pump.
Once you start using aircraft fuel, octane boosters, and my personal favorite TOULENE......forget get about it. As the robot in Lost in Space would say "Danger, Will Robertson!"![]()
Minus the SC guys, just drop 87 in it.
