Fuel Unleaded
Octane 87or higher
Tank 14US gal
Honda's owner's manual says the 2018 Honda CR-V takes unleaded gasoline, 87 octane or higher, and holds 14 US gal (53 L). It is built for fuel with up to 15% ethanol, never fuel with methanol, and Honda recommends TOP TIER detergent gasoline without manganese (MMT) additives. The table below gives the 2018 Honda CR-V fuel economy from the EPA for each engine and drive.
Lower octane fuel can cause a loud, steady metallic knock that damages the engine. If problems start after a fill-up, try another station or brand.
How to refuel
The 2018 Honda CR-V has no fuel cap. The fuel door is on the left rear side, so stop with the pump on that side.
How to refuel the car: 5 steps
- Stop with the pump on the left rear side and turn the engine off.
- Pull the fuel door release under the lower left corner of the dashboard.
- Put the nozzle in slowly and fully, resting on the bottom of the filler, and hold it level.
- Fill until the nozzle clicks off, then wait about 5 seconds before you take it out. Do not top off.
- Close the fuel door by hand.
Use only a gas station nozzle, since a siphon hose can damage the filler. If the nozzle keeps clicking off before the tank is full, try another pump, then see a dealer.
Low fuel light and range
The low fuel light comes on with about 2.1 US gal (8.0 L) left, so refuel soon. If it blinks, the fuel gauge has a problem and needs a check. Running the tank dry can make the engine misfire and damage the catalytic converter. The range display estimates the miles left from the fuel economy of past trips, so treat it as a guide.
If you run out of fuel
How to add fuel from a can: 5 steps
- Turn the engine off and make sure the can holds gasoline.
- Press the edge of the fuel door until it pops open.
- Fit the funnel from the tool kit in the cargo area. Do not use any other funnel or nozzle.
- Pour the fuel in slowly.
- Wipe the funnel clean, put it away and close the fuel door by hand.
How to get better fuel economy
Honda's manual lists the basics: service the car when the Maintenance Minder asks, use the recommended oil viscosity, keep the tires at the doorjamb pressure, carry no extra weight and clear snow or mud from under the car. To measure your own fuel economy, divide the miles driven by the gallons used at a fill-up.
