Q: Car using a lot more gas

asked by on

Car using a lot more gas.

Lack of maintenance may be the cause for the drop in fuel economy. The vehicle does not have variable valve operation, but does have displacement on demand where the engine’s computer actually shuts down cylinders to save some fuel. Have a mechanic, like the ones at YourMechanic, run an inspection on your vehicle’s reduced gas mileage and scan the computer’s data for abnormalities.
