Toyota Grand Highlander (AS10): Fuel information
You must only use unleaded gasoline.
Select octane rating 87 (Research Octane Number of 91) or higher. Use of unleaded gasoline with an octane rating lower than 87 may result in engine knocking.
Persistent knocking can lead to engine damage.
At minimum, the gasoline you use should meet the specifications of ASTM D4814 in the U.S.A.
■Gasoline quality
In very few cases, driveability problems may be caused by the brand of gasoline you are using. If driveability problems persist, try changing the brand of gasoline. If this does not correct the problem, consult your Toyota dealer.
■Recommendation of the use of gasoline containing detergent additives
- Toyota recommends the use of gasoline that contains detergent additives to avoid the build-up of engine deposits.
- All gasoline sold in the U.S.A. contains minimum detergent additives to clean and/or keep clean intake systems, per EPA's lowest additives concentration program.
- Toyota strongly recommends the
use of Top Tier Detergent Gasoline.
For more information on Top Tier Detergent Gasoline and a list of marketers, please go to the official website www.toptiergas.com.
■Recommendation of the use of low emissions gasoline
Gasolines containing oxygenates such as ethers and ethanol, as well as reformulated gasolines, are available in some cities. These fuels are typically acceptable for use, providing they meet other fuel requirements.
Toyota recommends these fuels, since the formulations allow for reduced vehicle emissions.
■Non-recommendation of the use of blended gasoline
- Use only gasoline containing up to
15% ethanol.
DO NOT use any flex-fuel or gasoline that could contain more than 15% ethanol, including from any pump labeled E30 (30% ethanol [A] ), E50 (50% ethanol [B] ), E85 (85% ethanol [C] ) (which are only some examples of fuel containing more than 15% ethanol).
- If you use gasohol in your vehicle, be sure that it has an octane rating no lower than 87.
- Toyota does not recommend the use of gasoline containing methanol.
■Non-recommendation of the use of gasoline containing MMT
Some gasoline contains an octane enhancing additive called MMT (Methylcyclopentadienyl Manganese Tricarbonyl).
Toyota does not recommend the use of gasoline that contains MMT. If fuel containing MMT is used, your emission control system may be adversely affected.
The malfunction indicator lamp on the instrument cluster may come on.
If this happens, contact your Toyota dealer for service.
■If your engine knocks
- Consult your Toyota dealer.
- You may occasionally notice light knocking for a short time while accelerating or driving uphill. This is normal and there is no need for concern.
NOTICE
■Notice on fuel quality
- Do not use improper fuels. If improper fuels are used, the engine will be damaged.
- Do not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle's three-way catalytic converters causing the emission control system to malfunction.
- Do not use gasohol other than
the type previously stated.
Other gasohol may cause fuel system damage or vehicle performance problems.
- Using unleaded gasoline with
an octane number or rating
lower than the level previously
stated may cause persistent
heavy knocking.
At worst, this may lead to engine damage and will void the vehicle warranty.
■When refueling with gasohol
Take care not to spill gasohol. It can damage your vehicle's paint.
■Fuel-related poor driveability
If poor driveability (poor hot starting, vaporization, engine knocking, etc.) is encountered after using a different type of fuel, discontinue the use of that type of fuel.
