Fuel Unleaded
Octane 87or higher
Tank 14US gal
Honda's owner's manual specifies unleaded gasoline, 87 octane or higher for the 2019 Honda CR-V, and the tank holds 14 US gal (53 L). The engine tolerates fuel with up to 15% ethanol but never methanol. Honda also suggests TOP TIER detergent gasoline free of manganese (MMT) additives. EPA fuel economy for each engine and drive is in the table.
Fuel under 87 octane may produce a loud, steady metallic knock that harms the engine. After a fill-up that causes trouble, switch to another station or brand.
How to refuel
This car has no fuel cap, and the fuel door is on the rear left, so park with that side next to the pump.
How to refuel the car: 5 steps
- Pull up with the rear left side at the pump and shut the engine off.
- Release the fuel door with the handle low on the left of the dashboard.
- Push the nozzle all the way in so it rests on the bottom of the filler opening, and keep it level.
- Fill until the nozzle shuts off on its own, wait roughly 5 seconds, then withdraw it. Never top off the tank.
- Shut the fuel door with your hand.
Use a service station nozzle only, because a siphon hose can harm the filler. When the nozzle keeps shutting off with the tank not full, switch pumps, and if it persists see a dealer.
Low fuel light and range
With about 2.1 US gal (8.0 L) left, the low fuel light turns on, so plan to refuel. A blinking light means a gauge fault that needs checking. An empty tank can cause misfires and ruin the catalytic converter. The range readout uses past trips' fuel economy to estimate the miles left, so it is only a guide.
If you run out of fuel
How to add fuel from a can: 5 steps
- Shut the engine off and confirm the can contains gasoline.
- Press the fuel door's edge so that it pops open.
- Insert the funnel stored in the cargo area tool kit. Use no other funnel or nozzle.
- Pour in the fuel gently.
- Wipe the funnel, stow it, and close the fuel door by hand.
How to get better fuel economy
The manual's basic advice is to service the car whenever the Maintenance Minder asks, use the recommended oil viscosity, keep tire pressure as on the doorjamb label, avoid carrying extra weight and keep snow and mud off the underside. To measure real fuel economy, divide miles driven by gallons added at a fill-up.
