Lexus ES250 2023 Fuel Information User Manual
Introduction
The premium automobile division of the Japanese automaker Toyota, Lexus, produces the Lexus ES250, a sedan. I don’t have the specifics for the 2023 model, but I can give you some general knowledge about how fuel considerations apply to automobiles.
Fuel Type: Petrol is the preferred fuel type for the Lexus ES250. For optimum performance, it’s crucial to utilize the fuel type that the manufacturer has recommended. For further information on the precise fuel needs of the 2023 model, consult the user guide or get in touch with Lexus customer service. Petrol is available in a variety of octane ratings, often 87, 89, or 91. The suggested octane rating for the Lexus ES250 can be found in the owner’s manual or on the gasoline filler door.
Fuel Economy: Details on fuel efficiency, including projected miles per gallon (MPG) or litres per 100 kilometres (L/100km) for both city and highway driving, are included in the Lexus ES250 2023 user handbook. Depending on the road, the gasoline, and the individual driver, this can change.
Fuel Tank Capacity
The vehicle’s fuel tank capacity, or how much fuel it can contain, should be mentioned in the user handbook. Planning refuelling stops for lengthy journeys might be aided by the information provided.
Fuel Information
You must only use unleaded gasoline.
Select octane rating 87 (Research Octane Number 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, drivability problems may be caused by the brand of gasoline you are using. If drivability problems persist, try changing the brand of gasoline. If this does not correct the problem, consult your Lexus dealer.
Recommendation of the use of gasoline containing detergent additives
- Lexus 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.
- Lexus 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. 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.
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.
- Lexus 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). Lexus 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 hap-pens, contact your Lexus dealer for service.
If your engine knocks
- Consult your Lexus 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 dam-aged.
- 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 dam-age and will void the vehicle warranty.
Fuel-related poor drivability
If poor drivability (poor hot starting, vaporization, engine knocking, etc.) is encountered after using a different type of fuel, discontinue the use of that type of fuel.
When refueling with gasohol
Take care not to spill gasohol. It can damage your vehicle’s paint.

Uniform Tire Quality Grading
This information has been prepared in accordance with regulations issued by the National Highway Traffic Safety Administration of the U.S. Department of Transportation. It provides the purchasers and/or prospective purchasers of Lexus vehicles with information on uniform tire quality grading. Your Lexus dealer will help answer any questions you may have as you read this information.
DOT quality grades
All passenger vehicle tires must con-form to Federal Safety Requirements in addition to these grades. Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example: Treadwear 200 Traction AA Temperature A
Treadwear
The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and a half (1 – 1/2) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use. Performance may differ significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate.
Traction AA, A, B, C
The traction grades, from highest to lowest, are AA, A, B and C, and they represent the tire’s ability to stop on wet pavement as measured under con-trolled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire is based on braking (straight ahead) traction tests and does not include cornering (turning) traction.
Temperature A, B, C
The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. Grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law.
Warning: The temperature grades of a tire assume that it is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combi-nation, can cause heat buildup and possible tire failure.
